P2M = person-to-merchant; P2P = person-to-person.
A UPI QR being accepted by selected merchants abroad is not the same thing as linking two countries’ instant-payment systems.
Singapore’s UPI-PayNow connection, Nepal’s P2P linkage and the new Maldives Favara-UPI corridor go further because they facilitate real-time cross-border account transfers.
For example, under the Maldives link launched on 30 July 2026, a person can initiate a transfer in Maldivian rufiyaa through Favara and the recipient’s UPI-enabled Indian account receives Indian rupees.
