Virtual address management

The solution securely maps VPAs created by users and assigns them to their bank account details. During a push or pull transfer by the user, the VPA is translated by FSS UPI and the payment message exchanged with the central infrastructure to complete the payment. Flexibility with the issuance of VPAs - time/amount bound, one-time offers users the ability to better control their payment options.

Notifies Merchants for Payment Guarantee

When a customer selects Pay by UPI from the Merchant App, the solution invokes all UPI Apps in the customer’s mobile device so users can choose a UPI app of their choice. For all merchant transactions that are completed, FSS UPI PSP sends customers on the confirmation of the payment along with the merchant name.
