Ability to decode proprietary data structures and export card data for further analysis. Typical Use Cases and Applications smartcard decoding program 2021

: Communication relies on Application Protocol Data Units. APDUs consist of Command APDUs (sent by the host) and Response APDUs (returned by the card). A decoding program captures, logs, and parses these hex pairs into human-readable text. Prominent Decoding Software and Frameworks in 2021 Mapping out the Master File (MF) and Dedicated Files (DF)
