NEW GUIDE: Using Web NFC #AdafruitLearningSystem #WebNFC @Adafruit

A new guide in the Adafruit Learning System today: Using Web NFC by Anne Barela

NFC stands for Near Field Communications and is a short range wireless technology operating at 13.56 MHz. Short range really means short range: in order to communicate, the devices have to be just a few centimeters apart or less.

Near Field Communications has been part of mobile phones since 2012, when Google launched the first NFC-enabled phone, the Google Nexus S. Most Android phones have NFC reading technology. Apple added their NFC technology in 2014 with the iPhone 6/6+ but tag reading is limited to the iPhone 7 and newer.

In May 2021, Chrome for Android 91 came out – that and subsequent versions supports Web NFC – any web developer can experiment and use NFC from simple HTML pages (rather than load a special NFC app).

This guide shows how to experiment with reading and writing tags using an Android phone and Chrome and suitable tags (which are also available from Adafruit).

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.
