What is an NFC Tag?
An NFC tag is a small electronic chip and antenna, usually on a sticker or label, that communicates wirelessly with an NFC-enabled smartphone at close range (about 10cm). Tapping a phone against an NFC tag instantly triggers actions like opening a URL, sharing a contact or making a payment. Built on NXP NTAG chips, NFC tags are widely used for smart marketing, product authentication and mobile interaction.
