📱 About Google Pay & Tokenization

Google Pay is a digital wallet platform that enables users to:

Store payment methods securely
Make contactless payments
Complete in-app/online purchases

Tokenization is the security process that:

Replaces sensitive card details with a unique token
This token is worthless if intercepted
The actual payment details never touch merchant servers
