NTAG213 / 215 / 216 vs ST25TV

Choose NTAG213, NTAG215, or NTAG216 if you need ISO/IEC 14443 Type A compliance and NFC Forum Type 2 Tag compatibility for consumer smartphone applications. These chips operate at 13.56 MHz and offer scalable user memory options: 144 bytes (NTAG213), 504 bytes (NTAG215), or 888 bytes (NTAG216). All variants include a 7-byte unique UID, ECC-based originality signature for authentication, 32-bit password protection, and field-programmable read-only locking. The Type A protocol ensures broad compatibility with Android and iOS NFC readers in close-proximity scenarios (typically under 5 cm). These are mass-market solutions suitable for product authentication, smart posters, loyalty cards, and consumer IoT where the reading device is a smartphone or Type A-compatible reader. Choose ST25TV if you require ISO/IEC 15693 compliance and NFC Forum Type 5 capabilities, particularly for applications demanding extended read range, tamper detection, or trusted sensing features. Operating at 13.56 MHz with 256 bytes of user memory, the ST25TV supports the Type 5 protocol that enables longer read distances (up to 1.5 meters with appropriate reader infrastructure) compared to Type A. Its tamper detection feature provides physical security monitoring, while the originality signature and 32-bit password protection secure data integrity. The Type 5 protocol is preferred in industrial logistics, supply chain tracking, and secure IoT deployments where inventory scanning from greater distances is required or where environmental sensing and tamper evidence add value beyond simple data storage. The ST25TV trades higher memory capacity for specialized security and sensing capabilities absent in the NTAG series.
