US Patent 11301853 Speculative transaction operations for recognized devices

Techniques are disclosed relating to speculatively processing transactions. A transaction processing system may receive an indication of a trigger event associated with an electronic transaction not yet initiated by a client computing device. In some embodiments, in response to the indication of the trigger event and prior to receiving an indication of the electronic transaction being initiated, the computer system begins speculative processing of the electronic transaction. In some embodiments, the speculative processing includes identifying the client computing device based on device authentication information received from the client device, determining a user account based on the identifier client computing device, retrieving account information for the determined account, and storing the retrieved account information. In response to receiving an indication of the electronic transaction being initiated, in some embodiments, the computer system performs one or more operations using the stored account information to complete the transaction.
