my-d move (SLE 66R01P) vs NTAG213 / 215 / 216

Choose the Infineon my-d move (SLE 66R01P) if you need a 16-bit value counter with anti-tearing protection, which is critical for loyalty cards, ticketing, or any application requiring reliable increment/decrement operations without data corruption during power loss. The chip provides 128 bytes of user memory (152 bytes total) and includes a password retry counter to prevent brute-force attacks, alongside 32-bit password protection that can be configured for read/write or write-only access. The 32-bit OTP (one-time programmable) area and block locking enable secure provisioning and immutable data storage. This chip operates at 13.56 MHz using ISO/IEC 14443-3 Type A and NFC Forum Type 2 Tag protocols, making it compatible with standard NFC readers while offering additional security features for controlled-access applications. Choose the NXP NTAG213/215/216 if you require larger user memory capacity or need ECC-based cryptographic originality verification. The NTAG213 offers 144 bytes user memory, NTAG215 provides 504 bytes, and NTAG216 delivers 888 bytes—significantly more than the my-d move's 128 bytes. The ECC-based originality signature allows readers to verify chip authenticity, making these variants ideal for anti-counterfeiting applications, product authentication, and brand protection scenarios. All three operate at 13.56 MHz with ISO/IEC 14443 Type A and NFC Forum Type 2 Tag compliance. They include 32-bit password protection and field-programmable read-only locking, plus a guaranteed unique 7-byte UID. However, unlike the my-d move, these chips lack a dedicated counter function and password retry limiting, making them better suited for read-mostly applications like smart posters, product labels, and consumer engagement tags where memory size and authentication matter more than transactional features.
