Calypso cards with serial number - System description WO
The Calypso serial number is an application ID for a 1TIC.ICA application.
The system is preset to read and process the entire serial number of an 8-byte Calypso card.
Some integrator systems cannot handle the entire length of 8 bytes. In this case, the SmartIntego tool in the SI-Tool: Kartenkonfiguration - Custom portion [offen] area offers to specify an offset and the length of the relevant area. The full length of 8 bytes can then be shortened to, for example, one byte.
The exact parameters can be found in the documentation of your integrator system.
