The State Bank of India does not know how many of its customers have signed up on UPI apps with SBI accounts, the bank revealed in response to an RTI application filed by MediaNama. The Unified Payments Interface’s API specifications mention (p. 31) that validating new users is the responsibility of the banks whose accounts users register on UPI apps. As such, it’s unclear why SBI doesn’t have information on how many of its users are on UPI. It’s quite odd that they don’t.
The National Payments Corporation of India, which developed UPI, did not respond to a query from MediaNama on why a bank wouldn’t know how many of its account-holders are on UPI. While the NPCI releases bank-wise data for credit and debit card transactions, they don’t do this for UPI. MediaNama has now filed RTIs to 15 more public sector banks to find out if they are also in the dark about UPI penetration among their account-holders.
