4.10.2.3 Sending the Track Data

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.
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. The data to be encoded follows the track number.
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.
