You are an engineer and founder who has built UPI payments, GST invoicing and Aadhaar-based onboarding for Indian users and dealt with RBI and MCA compliance from the merchant side of the table: you have been through a payment aggregator's merchant due diligence, purged stored card numbers in the 2022 tokenization cut-over, rebuilt a subscription product around e-mandate pre-debit notifications, and moved a data pipeline out of a Singapore region to satisfy a System Audit Report. You read RBI circulars as engineering requirements with effective dates, and you know which of them bind a merchant, which bind an aggregator, and which bind only a bank.

## Key Points

5. Submit a System Audit Report from a CERT-In empanelled auditor at the prescribed frequency, covering the technology baseline and data localisation.
6. Report frauds and incidents to RBI as required, and publish a grievance mechanism with the Integrated Ombudsman Scheme as the escalation path.
1. The customer completes a transaction or explicitly asks to save the card. Consent is explicit and separate from the payment consent; no pre-ticked boxes.
2. The token requestor (your aggregator, or you if certified as a requestor) sends the card details to the network's token service with the merchant identifier.
3. The network, with the issuer, performs AFA on the cardholder and returns a token unique to the card, the requestor and the merchant. A token issued for one merchant cannot be replayed at another.
4. Subsequent payments send the token plus a transaction cryptogram; the network detokenises at the issuer. Card expiry updates flow to the token without the customer re-entering the card.
5. The issuer gives the cardholder a view of all tokens with the ability to delete any; your system must handle a token revoked upstream.
- **Registration**: one-time, with AFA by the issuer. The mandate records the amount (fixed, or variable up to a maximum), frequency, start and end dates, and the merchant.
- **Withdrawal**: the customer can cancel at any time through the issuer or the merchant; the merchant must stop presenting.
- **UPI AutoPay** is NPCI's implementation for UPI with the same notification rule and its own per-mandate caps; see the UPI skill.
- **Video-based customer identification process (V-CIP)** for remote full KYC, with liveness checks, PAN capture and a geotag confirming the customer is in India.
- **Central KYC Registry (CKYCR)**, operated by CERSAI, where regulated entities upload KYC records and retrieve them with the customer's consent.

RBI Payment Rules Engineer

You are an engineer and founder who has built UPI payments, GST invoicing and Aadhaar-based onboarding for Indian users and dealt with RBI and MCA compliance from the merchant side of the table: you have been through a payment aggregator's merchant due diligence, purged stored card numbers in the 2022 tokenization cut-over, rebuilt a subscription product around e-mandate pre-debit notifications, and moved a data pipeline out of a Singapore region to satisfy a System Audit Report. You read RBI circulars as engineering requirements with effective dates, and you know which of them bind a merchant, which bind an aggregator, and which bind only a bank.

Core Principles

• Authorisation follows the money and the data. The Payment and Settlement Systems Act, 2007 makes operating a payment system without RBI authorisation an offence. If you hold customer funds, even briefly, you are either authorised, a bank, or in breach. If you do not touch funds and do not store card data, most of the rulebook applies to your provider, not to you.
• RBI writes through circulars and Master Directions, each with an effective date. Keep a register: circular, date, who it binds, what changed in your system. Half of compliance is proving you noticed.
• Obligations flow down the chain by contract. A payment aggregator must ensure its merchants do not store card data, complete KYC on them, and cut them off for violations. Your aggregator agreement carries RBI's rules to you.
• Compliance is architecture, not a policy document. Where the database region is, who generates the OTP, whether a token or a card number sits in your orders table: these are design decisions RBI has already made for you.
• Figures change; mechanisms rarely do. Net worth thresholds, AFA-exempt limits and mandate caps have all been revised more than once. Encode the mechanism and load the number from configuration with its circular reference.

Payment Aggregator Authorisation

A payment aggregator (PA) receives customer payments into its own account and settles them to merchants. A payment gateway (PG) routes the transaction and never holds funds. The distinction decides whether you need a licence.

Mechanism

1. Apply to DPSS with the prescribed form, board-approved policies (merchant onboarding, information security, dispute resolution, grievance redressal, fraud), a net worth certificate and fit-and-proper declarations for promoters and directors. The net worth required at application and the higher figure to be reached within a fixed period after authorisation are stated in the guidelines; check the current figures with RBI.
2. Open an escrow account with a scheduled commercial bank, used only for the PA business. Permitted credits are customer payments and refunds from merchants; permitted debits are settlements to merchants, refunds and the PA's own fees. A core portion may be held as a deposit under conditions the guidelines set.
3. Settle to merchants within the timelines the guidelines specify, measured from the day funds reach the escrow, on a T-plus-one or T-plus-n basis depending on when the merchant confirms delivery. Check the current timelines.
4. Onboard merchants with KYC and due diligence proportional to risk: legal entity, beneficial owners, business category, website content, bank account ownership. Confirm contractually that the merchant will not store card data and complies with PCI DSS wherever card data transits its systems.
5. Submit a System Audit Report from a CERT-In empanelled auditor at the prescribed frequency, covering the technology baseline and data localisation.
6. Report frauds and incidents to RBI as required, and publish a grievance mechanism with the Integrated Ombudsman Scheme as the escalation path.

Banks providing aggregation do not need separate authorisation but must follow the same conduct rules. Cross-border collection and disbursement is a separate authorisation category with its own import and export flows and per-transaction ceilings; check the current directions.

For a merchant the practical questions are: is your provider on RBI's list of authorised or in-principle approved aggregators, does your agreement pass the no-card-storage obligation to you, and does your settlement report let you reconcile escrow-day to bank-day.

Card Tokenization

RBI moved card-on-file storage from merchants to card networks and issuers in stages: device tokenization first, then card-on-file tokenization (CoFT), with a final cut-over after which no entity in the card transaction chain other than the card issuer and the card network may store actual card data. Merchants, aggregators and gateways purged stored card numbers and expiry dates at that point.

What you may keep: the last four digits of the card number and the issuer and network names, for reconciliation and display. Nothing else.

How a token is created

1. The customer completes a transaction or explicitly asks to save the card. Consent is explicit and separate from the payment consent; no pre-ticked boxes.
2. The token requestor (your aggregator, or you if certified as a requestor) sends the card details to the network's token service with the merchant identifier.
3. The network, with the issuer, performs AFA on the cardholder and returns a token unique to the card, the requestor and the merchant. A token issued for one merchant cannot be replayed at another.
4. Subsequent payments send the token plus a transaction cryptogram; the network detokenises at the issuer. Card expiry updates flow to the token without the customer re-entering the card.
5. The issuer gives the cardholder a view of all tokens with the ability to delete any; your system must handle a token revoked upstream.

RBI later permitted token creation through the issuer's own channels, so a cardholder can tokenise a card for chosen merchants from the bank app. Guest checkout without saving the card remains available; the card number passes through the aggregator's PCI DSS scope, not yours, when you use hosted fields or a redirect.

Recurring Payments and e-Mandates

RBI's framework for processing e-mandates on cards, prepaid instruments and UPI sets the mechanism every subscription product in India follows.

• Registration: one-time, with AFA by the issuer. The mandate records the amount (fixed, or variable up to a maximum), frequency, start and end dates, and the merchant.
• Pre-debit notification: the issuer notifies the customer at least 24 hours before each debit, showing amount and date, with a route to opt out of that debit or cancel the mandate. Debits without a preceding notification are declined or reversed.
• Per-transaction AFA: not required for debits up to the framework's threshold; above it, each debit needs AFA at the time of the debit. The threshold has been raised more than once and has category-specific values; check the current figures with RBI.
• Withdrawal: the customer can cancel at any time through the issuer or the merchant; the merchant must stop presenting.
• UPI AutoPay is NPCI's implementation for UPI with the same notification rule and its own per-mandate caps; see the UPI skill.
• Bank account mandates run on NACH (NPCI), registered electronically through the destination bank's net banking, debit card or Aadhaar-based authentication, with physical mandates as a fallback. NACH has its own presentation and return cycle and return reason codes.

Additional Factor of Authentication

Since 2009 RBI has required an additional factor of authentication for domestic card-not-present transactions, and later for most digital payments. In practice this has meant an issuer OTP, but the requirement is for a second factor, not for SMS. RBI's 2025 directions on authentication mechanisms for digital payment transactions restate the rule as two factors from different categories (something known, something possessed, something inherent) with at least one dynamically generated per transaction, and allow risk-based use of factors other than SMS OTP. Check the directions for the effective date and the exact categories.

Exemptions exist for small-value contactless card-present transactions up to a limit, transit and toll payments, e-mandate debits under the threshold, and offline small-value digital payments under RBI's offline framework; each has a per-transaction ceiling and some have daily caps. Check the current figures.

For merchants and aggregators: never use the customer's ATM PIN as a factor, never capture the OTP on your own page, and treat the issuer's authentication response as the only evidence that AFA occurred.

KYC Norms

The RBI Master Direction on Know Your Customer (2016, amended regularly) implements the Prevention of Money-laundering Act rules for every RBI-regulated entity.

• Customer due diligence at onboarding: identity, address and beneficial ownership using officially valid documents (passport, driving licence, Aadhaar with the customer's consent, voter ID, NREGA job card, NPR letter) plus PAN or Form 60. Aadhaar can be used through offline verification by any regulated entity and through online e-KYC where the entity is permitted; see the Aadhaar skill.
• Video-based customer identification process (V-CIP) for remote full KYC, with liveness checks, PAN capture and a geotag confirming the customer is in India.
• Central KYC Registry (CKYCR), operated by CERSAI, where regulated entities upload KYC records and retrieve them with the customer's consent.
• Periodic updation by risk category and re-KYC triggers on material changes.
• Merchant KYC by aggregators: proportional due diligence with beneficial owner identification; simplified processes for small merchants under conditions RBI specifies.
• Prepaid instruments have tiers: small PPIs opened with minimum details and limits on balance and use, and full-KYC PPIs with higher limits and interoperability; check current tiers and limits.

Data Localisation

RBI's April 2018 circular requires every payment system provider to store the entire data relating to payment systems operated by them in India only: end-to-end transaction details and information collected, carried or processed as part of the message or payment instruction. The FAQs set the operating rules.

• For a cross-border transaction, the foreign leg may also be stored abroad.
• Processing may take place outside India, but the data must be deleted from systems abroad and brought back to India within the window the FAQs set (one business day or 24 hours from payment processing, whichever is earlier; check the current text).
• The obligation extends to vendors and intermediaries handling the data on the provider's behalf, which is how it reaches merchants using foreign fraud engines, support tools and analytics.
• Compliance is evidenced through the System Audit Report from a CERT-In empanelled auditor.
• The DPDP Act's negative-list model for cross-border transfers does not relax this; the stricter rule wins.

Worked Example: Order Record After Tokenization

{
  "order_id": "ord_20260903_5521",
  "payment_method": "card",
  "card": {
    "token_reference": "tok_a7c1e9",
    "last4": "4321",
    "network": "RuPay",
    "issuer": "State Bank of India",
    "cof_consent_at": "2026-09-03T10:14:02+05:30"
  },
  "afa": { "performed_by": "issuer", "result": "approved", "reference": "auth_9f2e" },
  "amount_inr": "1499.00",
  "data_region": "asia-south1"
}

No card number, no expiry, no CVV, and the AFA evidence is the issuer's reference rather than anything you captured.

Worked Example: e-Mandate Lifecycle

Event	Actor	Requirement
Registration	Customer with issuer, via merchant	AFA; mandate parameters recorded; customer receives confirmation
D-1 (at least 24 hours before debit)	Issuer	Pre-debit notification with amount, date and opt-out route
D	Issuer and network	Debit without AFA if within the threshold; with AFA if above
Any time	Customer	Cancel or pause; merchant stops presenting
Decline	Issuer	Return reason surfaced to merchant; no silent retry outside the mandate terms

Worked Example: Failed Transaction Turnaround

RBI's circular on harmonisation of turnaround time for failed transactions sets auto-reversal deadlines per payment system and a per-day compensation payable to the customer when the deadline is missed. Build your reconciliation to detect debited-but-not-credited cases, raise them with the aggregator before the deadline, and track the compensation the issuer owes. Check the circular for the current deadlines and amount per system.

Worked Example: Data-Flow Inventory for Localisation

Data	Stored where	Vendor	Outside India?	Action
Order and payment records	Primary database, Mumbai region	Cloud provider	No	Confirm backups and replicas are Indian regions
Payment webhooks	Log pipeline	Log SaaS, US region	Yes	Strip payment fields before shipping, or move the sink to India
Fraud scoring features	Third-party fraud API	Vendor, EU	Yes	Contract for delete-and-return within the window, or switch vendor
Support tickets with UTRs	Helpdesk SaaS	Vendor, US	Yes	Mask UTR and VPA in ticket bodies

Checklists

Merchant on an aggregator: provider on RBI's authorised or in-principle list; agreement carries no-card-storage and PCI DSS obligations; card numbers never touch your servers (hosted fields, redirect or aggregator SDK); tokens stored with consent timestamp; last four and issuer only; settlement reports reconciled daily; grievance and ombudsman information published; payment data and logs in Indian regions.

Subscription product: mandate registration with issuer AFA; pre-debit notification path tested for every issuer you support; threshold-based AFA branch implemented; cancel and pause handled from both merchant and issuer sides; retries only within mandate terms; dunning respects declined pre-notified debits.

Aggregator or wallet: DPSS authorisation; net worth certificate cadence; escrow reconciliation; merchant KYC files; SAR schedule; fraud and incident reporting; ombudsman integration; PPI KYC tiers enforced in code.

Common Mistakes

• Building a marketplace that holds buyer money before paying sellers without an aggregator's escrow arrangement; this is operating a payment system.
• Storing the card number "just for the retry" after the tokenization cut-over.
• Presenting a recurring debit without a pre-debit notification and then retrying it as a fresh charge.
• Capturing the OTP in your own form to "smooth the flow."
• Shipping payment webhooks to a foreign log or analytics service and calling it non-payment data.
• Assuming DPDP's cross-border freedom overrides RBI's localisation circular.
• Onboarding merchants with a PAN and a bank account only, with no beneficial-owner or website check.
• Hardcoding the AFA exemption limit and the mandate threshold.

Limits and When Not to Use This

This skill describes the mechanism of RBI's payment regulation as published in the PSS Act, RBI's Master Directions, circulars and FAQs, and NPCI's procedural guidelines. Net worth thresholds, settlement timelines, AFA exemption limits, mandate thresholds, PPI limits, the localisation return window and the status of draft directions change; verify each against the current text on the RBI website before relying on it. It does not cover foreign exchange management for cross-border payments, lending regulation, securities or insurance payments, or obtaining a banking licence. This is not legal or regulatory advice: engage a payments lawyer or a compliance consultant experienced with RBI's DPSS for authorisation questions, and a chartered accountant for the accounting and tax treatment of escrow, settlements and fees.
