Card codings

This page contains changes which are not marked for translation.

On the card coding settings page you can select which card coding Fore! should use as default card coding when adding new cards.


You can you use 6 types of access card codings with Fore!:

  • Fore! default card
  • UID
  • Wiegand 26
  • Wiegand other
  • PX007A
  • Custom

Card codings for Sirius readers

The Fore! default card and UID are used in combination with Sirius F30, Sirius F80 and Sirius F80P card readers. When a card is presented to a Sirius reader it will first try to read it as a Fore! default card. If this fails it will try to read the UID of the card.

All card codings

Check the All card codings checkbox when you want to use all card coding. The readers will automatic choose the rights card coding when the card is present to a reader.

Fore! default card

The Fore! default card coding is used when you are using Fore! Mifare encoded cards. Fore! Mifare cards can only be created by Keyprocessor / Fore! and use an 8 digit decimal card number e.g. "21208521".

All manufactured Fore! Mifare access cards (and tags) have a unique card number encoded in their sector. The card numbers are generated in random order. The Fore! Mifare card uses a Mifare Classic chip. This card is the default option in Fore! and currently offers the highest level of security.


When you prefer to use your own access cards you can use any ISO/IEC 14443 Type A 13.56 MHz contactless smart card. Fore! will then use the unique identifier (UID) also known as card serial number (CSR) as a card number. Fore! uses a 14 digit hexadecimal byte swapped representation of the UID, for example "1a2b3c4d5e6f78" for a 7 byte UID or "0000001a2b3c4d" for a 4 byte UID.

You an use this option with most types of Mifare and Desfire access cards.

Card codings for Wiegand readers

If the Wiegand converter retrieves an input it will use the lenght of the input to determine which card coding should be used: if the input is 26 bit long a Wiegand 26 card number will be returned. If the input lenght is not equal to 26 bit it will return a Wiegand other card number.

Wiegand 26

A 26 bit input to the Wiegand converter is interpreted as a Wiegand 26 standard encoded access card. The format has one parity bit, 8 bits of facility code, 16 bits of ID code, and a trailing parity bit for a total of 26 bits. In Fore! this card is is represented using a 8 digit decimal number, e.g. "01200345" for a card with facility code "012" and card number "00345".

Wiegand other

All other input lenghts to the Wiegand converter are interpreted in the following way. The first and last bits are considered parity bits and not used. From the remaining bits the last 56 are converted to a 14 digit hexadecimal number e.g. "1a2b3c4d5e6f78".

Note In most cases this representation will not match the number that is printed on the card.



The Custom card coding can be use with card with a Secret and Offset. Set the right Secret parameter en Offset parameter and the card will start to count form 0001 till ....
