Sending the Track Information
Magnetic track data is sent in the form of text strings from the application software to the Printer
Driver.
In order for the Printer Driver to differentiate between Magnetic Track data and the rest of
the printable objects, specific characters must be added to the magnetic data to be
encoded.
These specify the data that is to be encoded, the tracks to encode and mark the start and
stop of the data string.
In some cases, these specific characters are automatically added to the string of track data
by ID software applications.
In most cases, the User must carefully add these characters to the string of Magnetic Track
data. If these characters are not added to the track data, the text intended for the Magnetic
Track will appear as printed text on the card.
To avoid this, track information must be entered as described below.
Step Procedure
1 When entering track data, the ~ (tilde) character is entered first, followed by
the track number (1, 2 or 3) on which the data should encode. This is
followed by the data to be encoded
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.
