Description

When Entry Point is re-started following an Online Request Outcome (e.g. to process the online response), Entry Point needs to activate the previously selected combination to process the online response (i.e. Chapter 3.3.3, Final Combination Selection). This specification bulletin clarifies Entry Point’s processing in Final Combination Selection for the situation where Entry Point sends the SELECT (AID) command with the ADF Name from the previously selected combination, but the card responds with a Status Word different from 9000. Please note that this specification bulletin applies to both versions 2.4 and 2.3 of the EMV Contactless Specifications and supercedes SB-143.
