Google Pay's Tap to Pay feature, launched in 2020, allows contactless payments using NFC technology. Initially compatible with only two banks, it now works with most major debit and credit cards in India. Users can add their cards to Google Pay, and payments can be made by selecting the card and tapping the phone near a point-of-sale machine. The feature supports most Visa and MasterCard cards issued in India, while American Express cards are excluded. There are no transaction limits, and a PIN is required for high-value transactions. The setup process involves adding card details and authenticating via SMS. Tap to Pay can also be used internationally, except in China.
