India, May 18 -- The National Payments Corporation of India (NPCI) is working on building a common interoperable infrastructure for UPI soundboxes to enable a single device to process UPI payments across different payment apps.

Citing sources, ET reported that the back-end infrastructure would allow merchants to accept payment from any QR code and use the same device for the settlement services. The NPCI's common platform would be compatible with QR codes of all fintech players.

The infrastructure would allow merchants to receive payment confirmations through a single soundbox, regardless of the QR code used by customers for the transaction, the sources added.
