The Reserve Bank of India could act after a Feb. 29 deadline it has set, after which Paytm Payments Bank will bar customers from replenishing their saving accounts or the popular digital payment wallet, the people said.

Violations included misuse of customer documentation rules and non-disclosure of material transactions, they added, asking not to be identified as the details are private.

No final decision has been reached as yet and the RBI’s thinking may change based on Paytm’s representation, the people said.

The RBI didn’t respond to an email seeking comment.

A Paytm Bank spokesperson said the recent direction from the central bank is “part of the ongoing supervisory engagement and compliance process.” The bank has also heeded to compliance and supervisory instructions from the regulator, the spokesperson said.

Hundreds of thousands of Paytm Payments Bank customers hadn’t submitted know-your-customer documentation, a single identity document was used to register thousands of customers in some cases, and transactions running into tens of millions of rupees — far beyond regulatory limits — were being done in minimum-KYC accounts, which raised money-laundering concerns, according to the people.
