ICC Track 2 Equivalent Data

ICC cards can optionally contain a data element (Track 2 Equivalent Data) within the chip. This data element is identified as Tag 57 defined both by the EMV and American Express ICC Payment Specifications. It contains an image of the Track 2 Data present on the magnetic stripe of the card. See the tables above for a definition.

Note: That the start and end sentinels, and LRC that are present on the magnetic stripe are not present in the Track 2 Equivalent Data.
