NFC Forum Type 2

NFC Forum Type 2 is the most widely deployed NFC tag type, based on ISO 14443-3A with 106 kbps data rate. Type 2 tags use a 4-byte page structure and support NDEF message formatting for interoperable data exchange. Major implementations include NXP NTAG 21x series and MIFARE Ultralight. Type 2 tags offer the best balance of cost, compatibility, and functionality for consumer NFC applications.
