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 most likely appear as
printed text on the card. To avoid this, track information must
be entered as follows.
When entering track data, the Ò~Ó character is entered first,
followed by the track number (1, 2, or 3) on which you intend
to encode the data. The data to be encoded should then follow.
The first character of this data string must be the trackÕs
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 trackÕs maximum character capacity. When segmenting
track data, the appropriate Field Separator (FS) must be used.
The following table shows the SS, ES, FS, and the valid
characters defined for each track.
The following example illustrates how track data should be
entered for tracks 1, 2, and 3:
