While it just looks like 13.56MHz RFID — using Mifare or similar low cost tags … it’s nice to see technology making inroads in my own backyard. I’ve always appreciated some legislation in Europe that forces food retailers to publish comparable prices on the tags of every product. (All products need to have the price per KG or per liter listed on the in-store tickets so you can easily compare. The difference with some products can be shocking.) Something like NFC/RFID allows you to also see the nutritional information more easily, etc., which can only be a good thing.

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.
