Picked up a Flipper, read your RFID Card but afraid of messing with the “Write card” feature in fear of wiping your card? Or maybe you’re working on an RFID Project with a Raspberry pi or Arduino. If so, you have come to the right place!
This is a Rabbit-Labs branded WRITABLE (arrives blank) RFID Keychain tag that can be used alongside the flipper (or other RFID Reader/Writer). Unlike many similar tags found on Amazon or Ebay, this chip uses a genuine ATMEL T5557 RFID Chip (specifications are listed below). This chip is fully writable and can be used to copy any other T5557 compatible fob or card.
- 100kHz to 150kHz Compatibility
- e5550 Binary compatible or T5557 Extended mode
- ISO/IEC 11784/785 Compatibility
- 7x 32-bit EEPROM Data memory including a 32-bit password
- Separate 64-bit memory for Traceability data
- 32-bit configuration register in EEPROM











Easy to use and easy to carry works great
I purchased this tag specifically because my neighborhood club house wanted to charge me $45 for a second key. Problem solved with this key tag. I love the idea of the “follow the white rabbit” theme. Rabbit labs never disappoints. Great place to get started with GPIO and the prices are pretty good! Thanks!
All 5 worked and were printed well. Super cool little rfid Keychain with cool logo the real ones will recognize haha.
I got it because it looks sick AF. Lol
Idk how else I would review a RFID tag?
Well, it works!
Does the job and well
