Track 2 data for a debit transaction.
This is a variable length field with a maximum data length of 37 characters. For Retail Card Present transactions, this property will contain the entire UNALTERED track as read from a credit card's magnetic stripe. This includes all framing characters. However, the track should be converted to 8-bit ASCII before this property is set (most card readers do this automatically).
Industry regulations do not allow merchants or processors to store track data in any form of persistent storage. Failure to abide by this regulation can result in significant fines and other penalties.
