Reverse Penny Drop

Banking & Credit

Verify bank account ownership by having the person pay one rupee via UPI.

Instead of pushing money to an account, ask the person to pay a token amount from it. The transfer reveals the account number, IFSC and registered holder name, proving they control the account. Higher assurance than a penny drop, with the rupee refunded automatically.

About this API

A conventional penny drop confirms an account exists and whose name it carries. A reverse penny drop goes further: because the person initiates the payment from their own UPI app, you learn the account details straight from the bank and prove the person controls it.

The flow is a link or QR: the person pays one rupee, the result posts to your webhook, and the rupee is refunded.

Consent. The person initiates the payment themselves, which is explicit consent. The transaction reference is stored with the result.

Typical uses

Loan disbursal account setup. Prove the borrower owns the payout account.
Gig partner onboarding. Capture verified payout details without a form.
Investment and broking. Link a verified bank account to a trading account.
Insurance claims. Verified beneficiary accounts before settlement.

Questions

Does the person need a UPI app?: Yes. Any UPI app linked to the account they want to verify.
What about accounts without UPI?: Use Bank Account Verification with the account number and IFSC instead.
