A Legal and Technical Guide for Global Payment Platforms
Payment data localization is reshaping how global payment platforms architect infrastructure, manage compliance, and serve regulated markets. India, Japan, and Brazil each impose distinct legal frameworks that now carry real enforcement consequences for non-compliance.
The regulatory bar is rising. Compliance timelines are shortening. And for payment platforms operating across borders, the architectural decisions made today will determine whether market access remains viable tomorrow.
Three of the world’s largest payment markets now impose enforceable data localization or transfer restriction regimes that directly affect how payment infrastructure is built, where payment data can reside, and what happens when those rules are violated. This article examines the precise legal architecture in India, Japan, and Brazil, and explains why data residency must be designed into payment systems from inception, not retrofitted after a regulatory audit.
What Payment Platforms Need to Know About Data Localization in 2026
India
India's RBI mandate requires all payment data stored domestically, with the DPDP Act adding penalties up to INR 250 crore (approximately USD 29–30 million depending on exchange rates) per instance.
Japan
Japan's APPI and FSA framework creates functional localization through layered cross-border transfer restrictions and supervisory access requirements.
Brazil
Brazil's LGPD transfer regime became fully enforceable in August 2025, with mandatory ANPD standard contractual clauses as the primary practical transfer mechanism for most organizations.
PCI DSS Scope
PCI DSS scope multiplies with every jurisdiction where cardholder data is stored, replicated, or retained.
Architecture-Level Data Minimization
Architecture-level data minimization can help organizations address localization, sovereignty, and PCI DSS obligations more effectively.
Build for Residency From the Start
Retroactive compliance is substantially more expensive than building data residency into the architecture from the outset.

India: Mandatory Localization Under a Dual Regulatory Regime
India operates the most explicitly prescriptive payment data localization regime of the three markets considered here, governed by two overlapping but distinct legal instruments: a sector-specific mandate from the Reserve Bank of India (RBI) and the recently operationalized Digital Personal Data Protection (DPDP) Act of 2023.
The RBI Storage Directive (2018)
The foundational instrument is the RBI’s circular dated April 6, 2018, issued under the Payment and Settlement Systems Act, 2007, directing all payment system operators (PSOs) to ensure that “the entire data relating to payment systems operated by them are stored in a system only in India.” The directive defines covered data broadly, encompassing end-to-end transaction data from payer to beneficiary, payment instructions, and the data generated by the payment system provider itself.
The circular does permit data to be processed outside India for the purpose of cross-border transaction flows, subject to a critical condition: any such data must be deleted from foreign systems and repatriated to India within 24 hours of processing. This is not a mirroring or backup permission. It is a time-bounded processing exception. The primary and sole data of record must reside domestically.
The consequences of non-compliance have been demonstrated in practice.
In July 2021, the RBI exercised its supervisory authority under the Payment and Settlement Systems Act to prohibit Mastercard Asia Pacific from onboarding new domestic customers, citing its failure to comply with the 2018 storage directive. The restriction was lifted only after Mastercard provided the RBI with satisfactory evidence of full compliance. American Express and Diners Club International faced similar restrictions during the same period. The episode established, unambiguously, that the RBI’s localization mandate carries enforcement teeth.
The DPDP Act, 2023, and the Draft DPDP Rules, 2025
The Digital Personal Data Protection Act, 2023, enacted by Parliament under Article 246 of the Indian Constitution and signed into law on August 11, 2023, establishes India’s first comprehensive statutory framework for personal data protection. Unlike the RBI’s sector-specific mandate, the DPDP Act applies across all industries and to any entity processing the personal data of individuals in India.
The Act departs from earlier legislative proposals that contemplated hard localization of sensitive and critical personal data. Instead, Section 16 adopts a “negative list” model: personal data may be transferred outside India to any country or territory unless the Central Government, by notification, restricts transfers to that jurisdiction. The Central Government retains discretionary authority to designate restricted destinations, taking into account factors such as adequacy of data protection in the recipient jurisdiction and the strategic interests of India.
This general openness, however, is materially constrained in the payments sector by the continuing force of the RBI directive, which is sector-specific and imposes a stricter standard. Under the interpretive principle of lex specialis (that a specific law governs over a general one) and as confirmed in the DPDP Rules, 2025 (notified by MeitY in November 2025, following a January 2025 draft consultation), Rule 15 provides that sector-specific localization mandates from regulators such as the RBI are unaffected and continue to prevail. Where the two regimes conflict, the stricter norm applies.
The DPDP Rules, 2025 introduce enhanced obligations for entities classified as “Significant Data Fiduciaries” (SDFs), a category MeitY will designate by notification, likely to include major payment processors, digital wallets, and financial intermediaries processing data at scale. SDFs face additional duties under Rule 12(4), including data localization requirements that go beyond the general framework applicable to ordinary data fiduciaries. SDF obligations, including cross-border transfer restrictions and mandatory Data Protection Officer appointments, take effect in November 2026.
India’s DPDP Rules, 2025 were notified by MeitY on November 13, 2025 (Gazette notification G.S.R. 846(E)), and are now in force under a phased implementation timeline. The Data Protection Board is operational, the Consent Manager and Significant Data Fiduciary obligations (including cross-border transfer restrictions, breach notification requirements, and Data Protection Officer mandates) take effect in November 2026, and full substantive compliance obligations for Data Fiduciaries are scheduled for May 2027. Organizations should use the phased implementation period to prepare for Significant Data Fiduciary obligations and full compliance requirements.
Practical Legal Exposure in India
The convergence of the RBI’s PSO directive and the DPDP Act creates a compliance regime with two distinct enforcement mechanisms and two distinct sets of penalties. RBI violations may result in monetary penalties under the Payment and Settlement Systems Act and, as demonstrated, operational restrictions. DPDP Act violations carry financial penalties of up to INR 250 crore (approximately USD 29–30 million depending on exchange rates) per instance, with the Data Protection Board of India serving as the adjudicatory authority.

Dual Compliance Required
Payment platforms must account for both the RBI's sector-specific payment data requirements and India's broader data protection framework.
Japan: Functional Data Localization Without Explicit Localization Law
Japan presents a conceptually distinct model: a jurisdiction that imposes no statutory payment data localization requirement as such, but whose layered legal framework (spanning personal data protection law, sector-specific financial regulation, and national security legislation) produces functional localization requirements in practice.
The Act on Protection of Personal Information (APPI)
Japan’s primary data protection statute is the Act on Protection of Personal Information (Act No. 57 of 2003), substantially revised effective April 2022 in amendments that significantly tightened cross-border transfer obligations. The APPI is administered by the Personal Information Protection Commission (PPC), which has published general guidelines and, jointly with the Financial Services Agency (FSA), sector-specific guidelines for the financial sector.
Under Article 24 of the revised APPI, a personal information handling operator may not provide personal information to a third party located in a foreign country without either: (a) the data subject’s explicit, separately obtained consent to the transfer and to the legal environment of the destination jurisdiction; or (b) a determination that the recipient is located in a country designated by the PPC as having a legal system equivalent to Japan’s protections, or that the recipient has implemented equivalent organizational measures.
The PPC’s list of designated adequate jurisdictions is narrow. The European Union and the United Kingdom have been mutually recognized as adequate, with the adequacy decision between Japan and the EU renewed in March 2023 under Article 45 of the GDPR. No such mutual recognition exists with the United States, leaving U.S.-bound transfers reliant on consent mechanisms or individually negotiated contractual frameworks. This is a material constraint for global payment institutions whose infrastructure may route through American cloud providers.
Three principal exceptions to the consent requirement exist:
Adequacy Recognition:
Transfers to jurisdictions designated by the PPC as providing an equivalent level of personal information protection. The European Economic Area and the United Kingdom currently hold adequacy recognition.
Equivalent Measures:
Transfers to recipients that have established a system conforming to APPI-equivalent standards, typically through contractual arrangements or binding corporate rules.
Statutory Exceptions:
Limited circumstances including legal obligations, protection of life or property, and cooperation with government authorities where permitted under applicable law.
The 2022 amendments added a significant ongoing obligation: where a transfer relies on the equivalent-measures exception, the Japanese data controller must periodically verify that the recipient continues to maintain those measures and must provide information about those measures to data subjects upon request. This creates a continuing compliance burden, not a one-time contractual exercise.
FSA Oversight and Functional Localization
The Financial Services Agency exercises supervisory jurisdiction over banks, credit card companies, and licensed payment service providers under the Banking Act (Act No. 59 of 1981), the Payment Services Act (Act No. 59 of 2009), and the Act on Prevention of Transfer of Criminal Proceeds. The FSA’s supervisory guidelines require licensed financial institutions to maintain data governance arrangements that permit the FSA to access records and conduct examinations without undue impediment.
In practice, this creates what may be characterized as a functional localization requirement. Where payment data is stored in a foreign jurisdiction under a foreign legal system, the FSA’s ability to compel production in a supervisory examination or to respond rapidly to requests from investigative authorities may be compromised. Institutions that cannot credibly demonstrate regulatory access to their data, regardless of where it physically resides, face supervisory risk.
The Payment Services Act was amended in June 2025 to impose additional requirements on crypto-asset exchange operators, including requirements that a portion of customer assets be maintained domestically. The FSA’s working group is finalizing implementing regulations, but the directional signal (domestic retention of operationally critical assets and the data associated with them) is consistent with the broader trajectory of Japanese financial regulation.
The Economic Security Promotion Act and Payment Infrastructure
Japan’s Economic Security Promotion Act (Act No. 43 of 2022) designated specific critical infrastructure sectors, including financial services, as subject to enhanced supply chain security requirements. Entities designated as Specified Essential Infrastructure Service Providers are required to submit advance notification of, and receive government approval for, the introduction of equipment or software into their critical infrastructure if such changes pose supply chain risks.
On May 16, 2025, the Act on the Protection of Economic Security Information came into force, establishing a security clearance system for individuals with access to information designated as important to national security, including information relating to critical infrastructure and financial systems. The intersection of this statute with payment infrastructure, particularly for institutions serving Japanese government entities or systemically important financial institutions, remains an evolving area of legal interpretation.
Practical Legal Exposure in Japan
Japan does not publish a single penalty schedule for data localization non-compliance analogous to India’s or Brazil’s frameworks. FSA supervisory sanctions under the Banking Act and Payment Services Act may include business improvement orders, suspension of operations, and license revocation. APPI violations may result in criminal penalties of up to one year imprisonment or fines of up to JPY 1 million for individuals, and fines of up to JPY 100 million for legal entities. The PPC’s enforcement posture has grown materially more active since the 2022 amendments.
Brazil: LGPD Transfer Controls and ANPD Standard Contractual Clauses
Brazil’s Lei Geral de Proteção de Dados Pessoais (LGPD), Law No. 13,709/2018, establishes a comprehensive framework for personal data protection modeled in significant part on the EU’s General Data Protection Regulation. The LGPD has been in force since September 2020, but its cross-border transfer regime became materially more prescriptive with the publication of ANPD Resolution No. 19 on August 23, 2024, which approved mandatory Standard Contractual Clauses (SCCs) for international data transfers.
LGPD Cross-Border Transfer Framework
Articles 33 through 36 of the LGPD govern international transfers of personal data. Article 33 permits transfers only where one of several specified legal mechanisms applies. These include transfers to countries or international organizations recognized by the ANPD as providing an adequate level of data protection, transfers subject to appropriate contractual safeguards, binding corporate rules, specific consent from the data subject, and limited statutory exceptions.
As of 2026, the ANPD has not issued a broad adequacy list comparable to the European Commission’s adequacy decisions. For most organizations, therefore, contractual safeguards represent the primary practical mechanism for lawful international transfers.
ANPD Standard Contractual Clauses
Resolution No. 19/2024 introduced a set of Standard Contractual Clauses that organizations may incorporate into agreements governing international data transfers. The clauses are designed to ensure that personal data transferred outside Brazil receives protections consistent with the LGPD regardless of the destination jurisdiction.
Organizations relying on contractual safeguards were required to incorporate the ANPD’s approved clauses into relevant transfer agreements by August 23, 2025. The clauses must be adopted substantially as issued and establish obligations concerning data subject rights, security measures, onward transfers, transparency, regulatory cooperation, and responsibility between the exporter and importer.
That implementation deadline has now passed. As of 2026, organizations transferring personal data internationally under the contractual safeguard mechanism should already have the ANPD clauses incorporated into their relevant agreements.
Implications for Payment Platforms
For payment platforms, the LGPD transfer regime creates obligations that extend beyond the execution of contractual documentation. Organizations must be able to identify where personal data is transferred, determine the legal mechanism supporting each transfer, maintain records demonstrating compliance, and ensure that downstream processors and service providers observe the applicable safeguards.
Payment data environments are particularly complex because a single transaction may involve processors, acquirers, issuers, fraud systems, cloud infrastructure, analytics platforms, and other service providers operating across multiple jurisdictions. Each transfer relationship may create a separate compliance dependency.
The Banco Central do Brasil and Open Finance Brazil
Distinct from the LGPD, Brazil’s Banco Central do Brasil (BCB) oversees the Open Finance Brazil ecosystem, one of the most advanced consumer-directed open finance implementations in the world, launched under BCB Resolution No. 1 of May 4, 2020, and subsequently governed by a series of BCB and Conselho Monetario Nacional (CMN) normative instructions.
Within Open Finance Brazil, payment initiation service providers (PISPs) and account information service providers (AISPs) are subject to strict requirements governing the scope of data sharing, consent validity and revocation, data retention periods, and the technical standards under which data may be exchanged. The BCB’s normative framework creates a parallel data governance layer that applies specifically to financial data within the open finance ecosystem, irrespective of the LGPD’s broader requirements.
The intersection of LGPD and BCB regulation creates a dual-compliance obligation: institutions operating within Open Finance Brazil must simultaneously satisfy the BCB’s operational and technical requirements for data sharing and the ANPD’s requirements for data protection. Where these overlap (as they do on questions of consent, purpose limitation, and data subject rights) the more protective standard applies.
Practical Legal Exposure in Brazil
LGPD violations are subject to administrative sanctions of up to 2% of the offending entity’s gross revenue in Brazil in the prior fiscal year, capped at BRL 50 million per violation. The ANPD has signaled increasing willingness to exercise its enforcement authority. BCB violations carry separate administrative penalties under the Payment System Law (Law No. 12,865/2013) and the BCB’s supervisory regulations.
Payment system data must be stored in India.
Foreign processing is subject to the RBI's 24-hour requirement.
RBI operational restrictions and monetary penalties, with separate DPDP penalties.
No blanket localization mandate, but cross-border transfers are subject to layered controls.
APPI consent, adequacy, equivalent measures, or statutory exceptions may support transfers.
PPC enforcement plus FSA supervisory action for regulated financial institutions.
International transfers require a valid mechanism under the LGPD.
ANPD Standard Contractual Clauses are a primary practical transfer mechanism.
ANPD administrative sanctions and separate BCB supervisory penalties.
India, Japan, and Brazil use different legal mechanisms to govern payment data residency and international transfers, creating distinct compliance requirements for global payment platforms.
Structural Implications for Payment Architecture and PCI DSS Compliance
The foregoing legal analysis has direct structural consequences for any institution building or operating cross-border payment infrastructure at scale.
The central architectural problem is this: contemporary payment infrastructure is typically designed around centralized data systems, a single fraud engine, a unified transaction ledger, a global analytics platform. Data localization and transfer restriction regimes are structurally incompatible with this model. They require institutions to resolve, at the level of data architecture, where each category of payment data will permanently reside, what legal basis governs any movement of that data, and how that legal basis can be demonstrated to regulators on demand.
This produces several non-negotiable design requirements:
Data residency must be built into the data model from inception, not retrofitted after a regulatory audit.
Fraud and risk scoring systems that ingest transaction data must operate within compliant jurisdictions, with only aggregated or fully anonymized intelligence shared across borders.
Consent and transfer management infrastructure must be capable of tracking the legal basis for every cross-border data flow in real time, and of suspending or rerouting flows if a legal basis becomes unavailable.
Regulatory access infrastructure (the ability to produce complete, accurate records to domestic regulators within the response windows those regulators impose) must be designed as a first-class system requirement, not an operational afterthought.
For institutions that have already built centralized infrastructure and are entering these markets, the cost of retroactive compliance is substantially higher than the cost of building correctly at the outset. The architectural investment required to serve India, Japan, and Brazil in full legal compliance is significant. It is not, however, optional.
Every jurisdiction where cardholder data is stored, replicated, or retained adds systems to the cardholder data environment, expands PCI DSS audit scope, and increases assessment cost.
When localization rules require data copies in multiple regions, the PCI surface area multiplies accordingly. Architecture-level approaches to data minimization, specifically those that reduce the amount of sensitive data stored across jurisdictions, can fundamentally change this equation. Organizations remain responsible for complying with applicable data localization, privacy, financial services, record-retention, and regulatory access requirements regardless of the technology architecture employed.
How Vaultless Tokenization Addresses the Data Localization Challenge
This is the class of problem that vaultless, keyless tokenization architectures are designed to help address. Sensitive payment data is translated ephemerally and replaced with format-compatible tokens that reveal no meaningful information about the underlying sensitive value and are usable only through authorized retrieval workflows. The token can be used for business processing, analytics, routing, and operational workflows without exposing the original sensitive value. This helps organizations simplify data residency and localization requirements by reducing the amount of sensitive data that must be stored, replicated, and managed across jurisdictions.
Organizations can configure deployments so that sensitive payment data remains within designated jurisdictions while format-compatible tokens can be used across systems and regions according to policy. Region-pinned tokenization deployments can help organizations support data residency requirements by keeping sensitive data processing within designated jurisdictions, with policy-based access controls that restrict where and by whom data can be retrieved.
For payment platforms operating across India, Japan, Brazil, or any combination of regulated markets, this architectural approach can help convert a compounding compliance problem into a design property: with substantially less sensitive data within scope for localization, compliance management, and PCI DSS assessment activities, organizations can focus resources on the controls and obligations that remain rather than managing an expanding footprint of stored sensitive data.
Conclusion
Payment data localization is not a temporary regulatory fashion. It reflects durable sovereign interests in national security, in regulatory access, and in the protection of citizens’ financial data, interests that are unlikely to recede. India’s enforcement actions against global card networks, Japan’s expansion of its economic security legal framework into financial services, and Brazil’s operationalization of a full cross-border transfer regime with mandatory SCCs all point in the same direction: the regulatory bar is rising, compliance timelines are shortening, and enforcement is becoming more systematic.
Institutions that treat data localization as a legal overhead to be minimized rather than as an infrastructural constraint to be designed around are accumulating compliance risk that will eventually manifest as regulatory sanction, forced remediation, or market exit. The markets are too large and the regulatory expectations too clear for this posture to be commercially defensible.
The legal frameworks in India, Japan, and Brazil are different in their specific requirements, but uniform in one respect: they require that payment institutions know, precisely and demonstrably, where their data is, who can access it, and under what legal authority it moves.
That standard of data governance is not merely a compliance obligation. It is, increasingly, a condition of market participation.

Frequently Asked Questions
Payment data localization refers to legal requirements that payment data generated within a jurisdiction must be stored, processed, or retained within that jurisdiction’s borders. It matters because non-compliance can result in operational restrictions (as seen with Mastercard in India), financial penalties up to INR 250 crore (approximately USD 29–30 million depending on exchange rates) per instance under the DPDP Act, and loss of market access. For fintech companies operating across borders, localization requirements directly affect infrastructure architecture, cloud deployment strategy, and PCI DSS audit scope.
Yes. The RBI’s 2018 storage directive requires all payment system operators to store the entire data relating to payment systems in a system only in India. Cross-border processing is permitted for international transaction flows, but all data must be deleted from foreign systems and repatriated to India within 24 hours. The DPDP Rules, 2025, notified in November 2025, add a separate layer of data protection obligations with penalties of up to INR 250 crore (approximately USD 29–30 million depending on exchange rates) per instance. Significant Data Fiduciary obligations, including cross-border transfer restrictions, take effect in November 2026, with full substantive compliance obligations scheduled for May 2027. Both the RBI directive and the DPDP regime are actively enforced.
Japan does not have an explicit statutory payment data localization requirement. However, the combination of the APPI’s cross-border transfer restrictions (Article 24), the FSA’s supervisory access requirements, and the Economic Security Promotion Act creates functional localization requirements in practice. Institutions that cannot demonstrate regulatory access to their payment data, regardless of where it physically resides, face supervisory risk including business improvement orders and potential license revocation.
Brazil’s LGPD regulates cross-border transfers through Article 33, with the ANPD’s Resolution CD/ANPD No. 19/2024 formalizing mandatory standard contractual clauses (SCCs) as the primary transfer mechanism. The enforcement deadline passed on August 23, 2025. The ANPD has not issued adequacy decisions for any country, including the United States, making the ANPD SCCs currently the primary practical mechanism for supporting cross-border transfers for most organizations. Non-compliance carries penalties of up to 2% of gross Brazilian revenue, capped at BRL 50 million per violation.
Every jurisdiction where cardholder data is stored, replicated, or retained adds systems to the cardholder data environment (CDE), expanding PCI DSS audit scope and increasing assessment costs. When localization rules require data copies in multiple regions, the PCI surface area multiplies. Architecture-level approaches that reduce the amount of sensitive data stored across jurisdictions, such as vaultless, keyless tokenization, can result in substantially less sensitive data within scope for localization, compliance management, and PCI DSS assessment activities.
Vaultless, keyless tokenization translates sensitive payment data ephemerally and replaces it with format-compatible tokens that reveal no meaningful information about the underlying sensitive value and are usable only through authorized retrieval workflows. Because sensitive data is translated ephemerally and organizations can deploy tokenization services within specific jurisdictions, data residency and localization requirements can often be addressed through architecture and policy design rather than broad replication of sensitive data. Region-pinned tokenization deployments can help organizations support data residency requirements by keeping sensitive data processing within designated jurisdictions. Organizations remain responsible for complying with all applicable regulatory requirements regardless of the technology architecture employed.
Yes. PCI DSS governs payment card data security but does not address regional data sovereignty or privacy regulations. An organization can satisfy PCI DSS requirements while simultaneously violating India’s RBI storage directive, the DPDP Act’s data protection obligations, Japan’s APPI cross-border transfer restrictions, or Brazil’s LGPD transfer requirements. Organizations operating internationally must architect systems that satisfy both PCI DSS and regional privacy and localization obligations simultaneously.
