NFC for Fun and Profit
summary
CoreNFC on iOS now reads and writes NDEF and can access native tag commands so apps can read raw bytes, parse vendor formats and write multiple payloads; iOS 13 adds writing and the convenience URI/text helpers. Demonstrations include using Shortcuts for background tag triggers, an Opal transit card read that returns serial, a −$6 balance, six recent journeys and a last-trip timestamp, and the 60‑second scan limit and Express Transit tap‑while‑dead behavior.
