Google Pay is a peer-to-peer payments app in India that allows bank account-to-bank account transfers using UPI (Unified Payments Interface). It aims to enable simple and fast payments without additional features. Google Pay uses BHIM UPI, which powers multiple bank accounts into a single mobile app. Security measures include a PIN for every transaction and login authentication via phone lock screen, fingerprint, or PIN. The app also offers social payments, business payments, referrals, scratch cards, and "Tez Mode" for sharing payments by audio QR code without exchanging private details. Google Pay targets young Indian users and supports multiple local languages.
