Abstract
A system may include a point-of-sale system that gathers payment card track data from a payment card and a payment card gateway that processes the track data to authorize purchase transactions. The point-of-sale system may remove sensitive data such as a portion of a primary account number from the track data and may compress the removed data. The compressed version of the data may be appended to a discretionary field in the track data. The discretionary field may be encrypted following insertion of the compressed data. Track data that has been modified in this way may be conveyed to the payment gateway for processing.
