This tiny micro NFC/RFID tag is super small and contains an NTAG215 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 wearable or whatever another tiny device with near field communication incorporated. Contains 144 bytes of read-write accessible memory
You can use this with our PN532-based RFID reader breakouts & shields and will work with all the latest cellphones or tablets that have NFC built-in. Note that since 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 cellphone with commands, URLs, unlocking, etc.
