In the Magnetic tab you can set the start and stop commands for the printers to encode the magnetic stripe. Most common start and stop commands can be found on our End-Users Forum. Of course, these settings can apply to all cards or the selected card only.
IMPORTANT! These Start and Stop commands only apply when using the old version 6 Designer! Magnetic encoding via CardExchange® Producer 7 and higher as well as TrustID is explained in the "Using Magnetic Encoding" section of this Help File! This Magnetic tab is hidden by default, to show it you need to enable the show advanced mappings option under Advanced Options.
