3.2.4 Magstripe ISO7811/2
The Magstripe ISO7811/2 (clock & data) and Wiegand interface share the same connections. This means that only
Wiegand or Magstripe can be used and not both simultaneously.
Magstripe connections
Shield connected to DC-ground
Message format
The Magstripe output format is determined by the programming format of the credential. Magstripe formatted
credentials will automatically generate a Magstripe message. If the credential is not programmed in Magstripe format,
you may configure the message output format as described in chapter 4.5.2.
Magstripe timing
The figure below shows the timing for one magstripe numeric character.
Each character contains 5 bits: 4 data bits (lsb first) and 1 parity bit (odd).
See for more details about encoding and character set the ISO7811/2 documentation.
