Custom Format Decoder

By default, Read‑a‑Card will read the CSN/UID of a contactless card and format it in one of six ways. If you want to format the CSN/UID differently, for example by reading only part of the UID, you will need the Custom Format Decoder plug‑in to ensure Read‑a‑Card can return that data, formatted according to your requirements.

The Custom Format Decoder supports reading and decoding UIDs from all card types supported by Read‑a‑Card. It can also be used to decode the credentials read from HID Prox or iClass cards, if a suitable HID/OMNIKEY reader is used.
