Near-Field Communication (NFC), The Alien Technology
summary
Shows practical Web NFC work: demos include iPhone Shortcuts triggering FaceTime and Tweets, Android Chrome using the Web NFC API to read/write/scan tags, and a live payment flow that reads a price and posts to PayPal/Google Pay. Tags cost ~\$0.30 each, offer ~514 KB memory, and support JSON, URL, text and media records. Code uses an abort controller to stop scanning, the API exposes scan/read/write promises, and tags can be locked read‑only; Web NFC works in Chrome on Android only.
