DESFire Decoder

By default, Read‑a‑Card will read the CSN/UID of a contactless card. If you want to read secure application data from a specific file on a DESFire card, you will need the DESFire Decoder plug‑in. This allows Read‑a‑Card to return that data, formatted according to your requirements. It will also allow you to optionally store access keys securely in hardware, using a SAM (secure access module).

Read-a-Card supports reading and decoding of IDs stored in a nominated secure file on DESFire EV1 and EV2 cards of any size (2K, 4K or 8K). It can work in conjunction with Dot Origin’s Key‑ID Encoder software, or with other solutions for encoding and managing DESFire cards in a multi‑application environment.
