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.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
