Reset card ATC (Application Transaction Count) in case of sync failure between what is saved in card's memory and the incremented data. The ATC is a counter, maintained by the chip card application (incremented by the chip), that provides a sequential reference to each transaction. A duplicate ATC, a decrease in ATC, or a large jump in ATC values may indicate data copying or other fraud.
Note: ATC reset only occurs on the Pismo platform. When a new transaction occurs, the ATC is synchronized with the chip's ATC.
