The introduction of UPI for NRIs is seen as a significant move due to the following reasons: 1. This move will bring advantages to families living abroad, international students, and local businesses. 2. In terms of transaction volume, this feature will transform the instant real-time payment system into a more merchant-oriented transaction rather than solely peer-to-peer. 3. NRIs can easily access UPI payments by linking their international SIM cards to their NRE and NRO accounts. Accountholders will not incur any additional charges.
