NTAG 213, NTAG 215, and NTAG 216 have been developed by NXP® Semiconductors as standard NFC tag ICs to be used in mass-market applications such as retail, gaming, and consumer electronics, in combination with NFC devices or NFC-compliant Proximity Coupling Devices. NTAG 213, NTAG 215, and NTAG 216 (from now on, generally called NTAG 21x) are designed to fully comply to NFC Forum Type 2 Tag and ISO/IEC14443 Type A specifications.
