13.56MHz RFID Keychain Fob (MIFARE Classic)
A 13.56MHz MIFARE Classic key fob in a durable keychain form factor. It is the companion tag for the MFRC522 and other 13.56MHz readers, ideal for door locks and access control where a card is less convenient to carry.
Compatible with
- MFRC522 13.56MHz reader/writer
- PN532 and other 13.56MHz readers
- Works alongside 13.56MHz MIFARE cards
Build it with Compoden's AI
Pairing a tag with the right reader and code trips up a lot of first builds. Describe your access-control or attendance project to Compoden's AI build assistant. It matches the tag to a compatible reader at the same frequency, checks every part against real stock, and hands you the wiring and the code.
Built and Backed by Compoden
We have spent 10 years supplying RFID, electronics, and robotics parts to makers, schools, and access-control projects across India. Every Compoden order includes our AI build companion to help you wire the reader, write the code, and get the tag reading on the first try.
Does it work with the MFRC522?
Yes. It is a 13.56MHz MIFARE Classic tag, exactly what the MFRC522 reads.
Is it the same as the RFID card, just a fob?
Functionally yes - same 13.56MHz MIFARE technology in a keychain shape.
Will a 125KHz reader read it?
No - this is 13.56MHz; use it with a 13.56MHz reader, not a 125KHz one.
