This tiny micro NFC/RFID tag is super small, and contains an NTAG203 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 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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
