Google Pay can remove a card automatically if the bank flags it for security, the card details change, or verification fails after an update or failed transaction.
This usually happens after a declined payment, app update, or when the bank temporarily blocks tokenized cards.
To add it back, first confirm with your bank that the card is active and allowed for online and tokenized payments, then update Google Pay to the latest version.
Open Google Pay, add the card again manually, and complete any SMS or banking app verification without switching apps mid-process.
If re-adding fails, clear Google Pay’s cache, restart your phone, and try again on a stable internet connection.
When the issue persists, consider filing a complaint on Xolvie to seek a resolution.
