Message Box
The Message Box always displays the result of the last action. Mostly, it indicates a
successful read or a successful write operation after swiping a card through the slot. When
the operation can be performed on more than one card, the result message provides a
count of successful card operations.
Card Type
This provides a selection of reading and writing track formats. Track formats are the
combination of the track density, bits per character, selection of Start & End Sentinels, and
other parameters. The Card Type pull down menu has four selections: ISO, AAMVA,
USER, RAW & PASS BOOK. Each card type is explained below. The settings for each
type are available in the Setup window. See the Setup section & Appendix B for more
information.
ISO
- The ISO format follows the requirements given in ISO Standard 7811-6 and
earlier versions. Density is in bits per inch. Bits per character include a parity bit.
The number of Data Characters given does not include the Start Sentinel (SS), the
End Sentinel (ES), or the Longitudinal Redundancy Character (LRC). The SS, ES,
& LRC are automatically inserted into the data when writing to the card tracks.

AAMVA
- The AAMVA format follows the same character formats as defined by the
ISO Standards. The maximum number of Data Characters for Tracks 1 & 3 is
different from the ISO format and Track 3 is alphanumeric, following the same format
as Track 1. The number of Data Characters shown does not include SS, the ES, or
the LRC characters.
