Abstract:
A method includes counting a number of successive information frame (I-frame) retransmissions due to a guard timer expiring. A contactless front-end (CLF) transmits the I-frame to a secure element (SE) over a single wire protocol (SWP) interface. The method also includes discontinuing I-frame retransmission when the count equals a retransmission threshold. The method further includes deactivating the SWP interface.
