If you are adding a custom Wiegand card format, you must define the Wiegand data fields that constitute the card format.

What you should know

A Wiegand field is composed of a series of bits. The maximum field length is 256 bits.

The order of the Wiegand fields for the card format is important. It corresponds to the order that field values are read from the Credential card data when using the Import tool.


  1. In the Custom card format editor, click Add an item () under the Wiegand fields section.
  2. In the Name field, type a name for the Wiegand field.
  3. In the Mask field, type the number of bits that are part of the Wiegand field.
    The bits are named according to their position in the card format, starting from 0. You can enter the masks as a list of comma-separated bit positions, or as a range of bit position. For example, the mask “1,2,3,4,5,6,7,8” can also be written as “1-8” or “1-4,5-8”. The order of the bits within the field is important (“1,2,3,4” is not the same as “4,3,2,1”).
  4. Click OK.
    The field is added in the Wiegand fields section.
