US Patent 11880819 Contactless fuel payment systems and methods

A system may receive, via an NFC tag disposed proximate a vehicle fuel tank, a fuel transaction request from a third-party POS NFC reader positioned proximate a fuel pump. The system may detect a user device being paired with a vehicle communication device of the vehicle to enable a short-range wireless communication. The system may determine that the user device is associated with an authorized user of the vehicle. The system may unlock the NFC tag to enable the NFC tag to communicate with the third-party POS NFC reader for a predefined time limit responsive to determining that the user device is associated with the authorized user. Responsive to unlocking the NFC tag, the system may retrieve account payment information associated with the authorized user, and may transmit, via the NFC tag, the account payment information to the third-party POS NFC reader to complete the fuel transaction.
