The host client that drives the Proxmark3 over USB — the `pm3` shell from the RfidResearchGroup/proxmark3 (Iceman) repo. Runs every Proxmark workflow from the laptop: `lf/hf search` to fingerprint a tag, read/dump LF IDs and HF cards, the full Crypto1 suite (`hf mf darkside`/`nested`/`hardnested`/`mfkey`), clone/simulate, and `hf 14a` sniff plus the `hf_reblay` standalone mode for an ISO 14443-A relay/MITM. The firmware and client ship together; this is the software you actually type into.
