Paste BER-TLV encoded EMV data and decode every tag — name, length, value, and a bit-by-bit breakdown for tags like TVR (95) and Terminal Capabilities (9F33). Format follows EMV Book 3, Annex B.
Parse some data to see the breakdown here.
Bit-level decoding is currently available for TVR (95), TSI (9B), AIP (82), Terminal Capabilities (9F33) and CVM Results (9F34) — the tags whose bit meanings are stable and consistently documented across EMV specifications. All other recognised tags show their name; unrecognised tags show the raw tag/length/value so nothing is silently hidden.
