Systems and methods for increased efficiency and reliability of contactless card transactions

Abstract

Example embodiments of systems and methods for performing a transaction involving a transmitting device and a receiving device. A state machine may be configured to monitor the data communications, data reads, and data writes performed between the transmitting device and the receiving device. In the event of a disruption during the transaction, the state machine may allow the transaction to resume following the most recent data communication, data read, or data write once the disruption is resolved.

         21 . An authorization system comprising:
 a processor; and   a memory,   wherein the processor is configured to:
 record one or more data operations from performed by a first device, 
 preserve, upon a communication interruption with the first device, the most recent data operation from the one or more data operations, 
 resume, upon resolution of the communication interruption with the first device, a transaction at a step following the most recent data operation from the one or more operations, and 
 display a communication status of the first device prior to authorizing the transaction.
