US Patent 11893581 Tokenization for payment devices

A payment device such as electronic transaction card or an near field communication device can use a temporary token for payment transactions. When processing a payment transaction, the temporary token is provided to a server of the issuer of the payment device, which can authorize the payment transaction and determine if the temporary token can be used for a subsequent transaction. If the server determines that the temporary token cannot be used for another transaction, the server provides the payment device with a new temporary token and an issuer script. When the payment device receives the issuer script, the payment device can execute the issuer script to store the new temporary token on the payment device.
