Sending ISO Magnetic Encoding Information
The CUPS Driver uses URL Encoding when defining data to be encoding to the Magnetic Stripe. Any special characters (such as start and end sentinels) must be described with URL encoding to be recognized. See the URL Encoding Reference for additional information.
∙The first character of this data string must be the track's specific Start Sentinel (SS) and the last character must be the specific End Sentinel (ES).
∙The characters or data in between the SS and ES can include all of the valid characters specific to each track.
∙The number of these characters, however, is limited by each track's maximum character capacity.
When segmenting track data, the appropriate Field Separator (FS) must be used. The table below shows the SS, ES, FS and the valid characters defined for each track.
