NFC Tag: What It Is & How It Works
An NFC tag is a tiny 13.56MHz chip that lets any smartphone tap-to-connect, storing a URL, contact or action that triggers on contact. NFC tags use NXP NTAG213, NTAG215 or NTAG216 chips with 144 to 888 bytes of memory, and need no battery or app. IDrfid manufactures custom NFC tags, NFC stickers and NFC labels since 2005, with pre-encoding and full-color printing.
