Partial data object acquisition and processing

Abstract:

A payment terminal such as a payment reader may receive and form electrical connections with an electronic transaction card such as an EMV chip card. The payment terminal may provide power to the electronic transaction card and initiate communications with the electronic transaction card. One or more records may be acquired from the electronic transaction card. Data objects may be extracted from those records and stored in a cache. Data objects may be needed to process transactions. If the data object is available from the data cache or is otherwise received prior to all records being received, transactions may be processed prior to the acquisition of all records from the electronic transaction card.
