ISO7811 track 1 details: 

Card loaded, Clock and Data signals are active-low. 
Timing per character is 1575 µsec, per bit 225 µsec (= ±4450 Hz). 
The characters are transmitted "backwards". Least significant bit first and ending 
with the odd parity bit. 
Number of leading and trailing clock zeros is 62.

MAGSTRIPE ISO7811 TRACK 2 

In this mode the license plate is converted to a magstripe ISO7811 track 2 
compatible output message. 
 
 

Syntax:   

<SS> <plate> <ES> <LRC> 

 

Where:   

<SS>

   

Start sentinel (hex B = bin 1011) 

 

  

 

<plate

>

  

License plate string (variable number of 

 

  

 

 

 

characters) 

 

  

 

<ES>

   

End sentinel (hex F = bin 1111) 

 

  

 

<LRC>

   

Checksum. Xor all message characters 

 

  

 

 

 

including <SS> and <ES>. 

 
ISO7811 track 2 data consists of 4 data bits + 1 odd parity bit for each character. All 
characters must be decimal numbers in the range from 0 to 9. Except for the start-
sentinel (hex B), end-sentinel (hex F) and LRC. 
 
Because the character set only contains decimal numbers, the license plate string 
must be converted from text to numbers. This conversion is done as shown in the 
conversion table below. 

 

 

Note 

The magstripe iso7811 
track 1 mode does not 
require to use the LAN 
connection. 
 
The magstripe iso7811 
track 1 mode is introduced 
in firmware version 1.05.
