Does UPI work in the USA?

Yes, the Unified Payments Interface (UPI) works in the USA for Indian users through the "UPI Global" feature. It allows you to make QR code-based payments at select international merchant stores using your Indian bank account. You must enable the "UPI Global" or "UPI International" feature in your UPI-powered app, such as Paytm, before making cross-border payments while traveling abroad.
