Adding a card to Google Wallet
It’s so frustrating! 
Rob ⚡️ changed the title to Adding a card to Google Wallet .
Google wallet bank cards are not supported in india right now
Bharathwaj which is secure app I can use then for adding cards
Maybe your bank app supports contactless payments? Then you can change options in nothingOS and set bank app as default for payments

SunCap IIRC, there is an app called Google Pay (separate to Google Wallet) that was for payments etc. in India, it may be what you are looking for
“In India, make UPI transfers or do mobile recharges, bills and payments to businesses with your bank account with Google Pay, a simple and secure payments app by Google.”
You can add your bank cards in Google pay and it’s supported only master and visa cards. Once added, then turn on NFC and place your phone on Card or payment reader machine.
SunCap Go for cred!
SunCap GPay let’s you add cards for tap and pay. Go over to the hamburger button and check tap and pay or cards to include. It lets you add debit and credit cards and then choose a default contactless payment card for tap and pay.
