RBI guidelines on Tokenisation – Card Transactions

The Reserve Bank has released guidelines on tokenisation for debit/credit/ prepaid card transactions as a part of its continuous endeavour to enhance the safety and security of the payment systems in the country. Tokenisation involves a process in which a unique token masks sensitive card details. Thereafter, in lieu of actual card details, this token is used to perform card transactions in contactless mode at Point Of Sale(POS) terminals, Quick Response(QR) code payments, etc.

These guidelines permit authorised card payment networks to offer card tokenisation services to any token requestor (third party app provider), subject to conditions enumerated in these guidelines. A cardholder may avail of these services by registering the card on the token requestor’s app after giving explicit consent. No charges shall be recovered from the customer for availing this service.

All authorised card payment networks

Madam / Dear Sir,

Tokenisation – Card transactions

Continuing the efforts to improve safety and security of card transactions, Reserve Bank of India had permitted card networks for tokenisation in card transactions for a specific use case.

1. It has now been decided to permit authorised card payment networks to offer card tokenisation services to any token requestor (i.e., third party app provider), subject to the conditions listed in Annex 1. This permission extends to all use cases / channels [e.g., Near Field Communication (NFC) / Magnetic Secure Transmission (MST) based contactless transactions, in-app payments, QR code-based payments, etc.] or token storage mechanisms (cloud, secure element, trusted execution environment, etc.). For the present, this facility shall be offered through mobile phones / tablets only. Its extension to other devices will be examined later based on experience gained.

2. All extant instructions of Reserve Bank on safety and security of card transactions, including the mandate for Additional Factor of Authentication (AFA) / PIN entry shall be applicable for tokenised card transactions also.

3. All other instructions related to card transactions shall be applicable for tokenised card transactions as well. The ultimate responsibility for the card tokenisation services rendered rests with the authorised card networks.

4. No charges should be recovered from the customer for availing this service.

5. Before providing card tokenisation services, authorised card payment networks shall put in place a mechanism for periodic system (including security) audit at frequent intervals, at least annually, of all entities involved in providing card tokenisation services to customers. This system audit shall be undertaken by empanelled auditors of Indian Computer Emergency Response Team (CERT-In) and all related instructions of Reserve Bank in respect of system audits shall also be adhered to. A copy of this audit report shall be furnished to the Reserve Bank, with comments of auditors on deviations, if any, from the conditions listed in Annex 1, along with the compliance thereto. Further, a report on the details provided in Annex 2 shall be submitted at monthly intervals to the Chief General Manager, Reserve Bank of India, Department of Payment and Settlement Systems, Central Office, Mumbai and by email.

6. This directive is issued under Section 10 (2) read with Section 18 of Payment and Settlement Systems Act, 2007 (Act 51 of 2007).

Yours faithfully,

(P Vasudevan)
Chief General Manager

Integrity of token generation process shall be ensured at all times.
