Google Pay is a digital payment system from Google that started under the nameAndroid Pay and was later renamed. Google Pay supports mobile payment(M-Payment) with Android smartphones. The payment system is secured by credit card and debit card accounts.
Google Pay works with mobile payment (M-Payment) and uses smartphones with the Android operating system for transactions. They form the payment terminals and communicate contactlessly using near field communication( NFC). The transaction data is transmitted in peer-to-peer( P2P). As far as credit cards are concerned, all well-known providers of digital payment systems rely on as many banks and credit card companies as possible. For the payment process itself, the user has to install an app and link the Google Pay account with a credit card.
For security reasons, the transactions, the credit card number and the account numbers are encrypted.
