Micro NFC/RFID Transponder - NTAG203 13.56MHz

This Micro NFC/RFID Tag combines an NTAG213 chip, integrated antenna and 144 bytes of read-write memory in a tiny flexible format for adding NFC functionality to compact wearables and custom projects.

This tiny micro NFC/RFID tag is super small, and contains an NTAG213 chip plus antenna.

It's super tiny, flexible and a great way to DIY an RFID or NFC device if you're interested in designing your own ring, wearable or whatever other tiny device with near field communication incorporated. Contains 144 bytes of read-write accessible memory.

You can use this with the PN532-based RFID reader breakouts & shields, and will work with all the latest cell phones or tablets that have NFC built in.

Please note: As the antenna is so small you'll need to put the tag right up against the device that's reading it. Can be used to control a cell phone with commands, URLs, unlocking, etc.
