nfc-mfsetuid(1)

nfc-mfsetuid 💖

okay so bestie, welcome to the nfc-mfsetuid page — it lives in the NFC Utilities corner of the manual, section 1, and it's genuinely one of the most iconic little tools in the libnfc lineup 🎀

✨ NAME ✨

nfc-mfsetuid — the MIFARE 1K special card UID setting and recovery tool 🫶

🌸 SYNOPSIS 🌸

nfc-mfsetuid [ UID ]

💅 DESCRIPTION 💅

so like, nfc-mfsetuid is a MIFARE tool, and what it does is it lets you set the UID on those special versions of Mifare 1K cards — you know the ones, the Chinese clones 👀

but wait, there's more, because it will also recover damaged cards 😭 like, cards that have had invalid data written to block 0 (for example a wrong BCC) — yeah, this tool pulls them back from the brink, no cap.

heads up tho: currently only a 4 Byte UID is supported. that's the vibe, that's the limit, periodt.

you either specify an eight hex character UID, or you leave it blank and get the default '01234567' 🌈

👑 OPTIONS 👑

• -f — Format. wipes all the data (sets it to 0xFF) and resets the ACLs back to defaults. it's giving factory reset energy 🔥
• -q — Quiet. suppresses the output of commands and responses. very demure, very silent 🤫
