DPDP Act for Fintech & BFSI: Complete Data Protection Compliance Guide 2026

Why Fintech and BFSI Face the Highest DPDP Compliance Stakes The fintech and BFSI (Banking, Financial Services, and Insurance) sector processes some of the most sensitive personal data in the Indian economy. From KYC documents and bank account details to credit scores and insurance claims, financial institutions handle data that can cause severe harm if mishandled. Under the Digital Personal Data Protection (DPDP) Act, this sector faces heightened scrutiny and potentially the strictest enforcement. What makes DPDP compliance particularly complex for fintech and BFSI is the overlap with existing regulatory frameworks. The Reserve Bank of India (RBI) already mandates data localization for payment data. The Insurance Regulatory and Development Authority of India (IRDAI) has its own data handling guidelines. SEBI regulates data in the securities market. DPDP adds another layer on top of these existing requirements, creating a multi-framework compliance challenge that demands careful coordination. This guide provides a practical, sector-specific roadmap for fintech and BFSI companies to achieve DPDP compliance while maintaining compliance with existing financial sector regulations. RBI Data Localisation and DPDP: Understanding the Overlap In April 2018, the RBI mandated that all payment system data must be stored exclusively in India. This directive, often called the "data localisation circular," predates the DPDP Act but intersects with it in important ways. What RBI Requires All data related to payment systems operated in India must be stored in systems located only in India This includes full end-to-end transaction details, information collected, carried, and processed as part of the message or payment instruction Foreign leg data of cross-border transactions may be stored abroad in addition to being stored in India How DPDP Adds to RBI Requirements While RBI's circular addresses where payment data is stored, the DPDP Act addresses how all personal data (including payment data) is collected, processed, and protected. The key additional requirements include: Consent requirements: DPDP mandates informed consent for data processing that goes beyond what RBI requires Purpose limitation: Data collected for payment processing cannot be used for unrelated purposes without separate consent Data principal rights: Customers have rights to access, correct, and erase their personal data under DPDP, even if RBI regulations require data retention Breach notification: DPDP requires notification to the Data Protection Board and affected individuals, in addition to any RBI-mandated reporting Resolving Conflicts When DPDP requirements appear to conflict with RBI mandates, the general principle is that sector-specific regulations may prevail for their specific domain, but DPDP provides the baseline for all personal data handling. In practice, this means complying with the stricter requirement in each case. Organisations should document their rationale for how they resolve any apparent conflicts. KYC Data Handling Under DPDP Know Your Customer (KYC) processes are fundamental to financial services, and they involve collecting extensive personal data. Under DPDP, KYC data handling requires specific compliance measures. Data Collected During KYC Aadhaar numbers and copies of Aadhaar cards PAN numbers and copies of PAN cards Passport details and copies Voter ID, driving licence, and other government-issued identifiers Photographs and biometric data (in some cases) Address proof documents Income proof and financial statements DPDP Requirements for KYC Data Purpose limitation: KYC data collected for account opening should not be used for marketing or cross-selling without separate consent Data minimisation: Collect only the KYC data required by regulatory mandate, not additional data "just in case" Retention limitation: KYC data should be retained only for the period required by applicable regulations (typically 5-8 years after account closure under PMLA) Security: KYC documents containing sensitive identifiers like Aadhaar must be encrypted and access-controlled eKYC and CKYC: Digital KYC processes must include proper consent flows and data security measures Payment Data Processing Under DPDP Payment data touches virtually every product and service in fintech and BFSI. Under DPDP, the processing of payment-related personal data requires specific compliance measures beyond what RBI regulations mandate. UPI Transaction Records UPI has become India's dominant payment method, generating billions of transactions. Each UPI transaction creates personal data including: Sender and receiver identifiers (VPA/UPI ID) Transaction amounts and timestamps Bank account references Merchant identifiers and transaction descriptions Device and location data used for fraud detection Under DPDP, consent for processing UPI data for the primary purpose of payment processing may be covered under legitimate uses. However, using UPI transaction data for analyti
