GET TRACK DECODE DATA COMMAND
Command ID: 82 (Hex)
Description:
This command is used to get decoded information related to a magnetic stripe read for a
single track. This command always returns data from the most current magnetic stripe
data acquisition. This command is used to get decode status, card encode type and
decoded card data for a given track. The track of decoded data starts with a start sentinel
and ends with an end sentinel and is converted to ASCII format. The ASCII
representation of the start and end sentinels vary depending on the encode format.
