TOPAZ 512

Features:

1. Complies with the Type 1 tag format mandated by the NFC Forum: TOPAZ 512 complies with the Type 1 tag format mandated by the NFC Forum, ensuring compatibility with various NFC devices.
2. For operation with NFC devices compliant with ISO/IEC 18092 (NFCIP-1) and ISO/IEC 21481 (NFCIP-2): Designed for compatibility with ISO/IEC 18092 (NFCIP-1) and ISO/IEC 21481 (NFCIP-2) Designed to operate with NFC devices.
3. Compatible with ISO/IEC 14443:2001 Parts 2 and 3: Adopts ISO/IEC 14443:2001 Type A modulation scheme to ensure communication stability.
4. Passive RFID tags operating in the unlicensed 13.56 MHz frequency band: By operating in the unlicensed 13.56 MHz frequency band, passive RFID tags can be read and written.
5. Read and write (R/W) operations: Provide read and write operations, supporting 8-byte read and 8-byte write commands.
6. Configurable for Once Programmable (OTP) and Read Once Many (WORM) operations: Flexible configuration to support Once Programmable and Read Once Many operations.
7. Fast data communication rate, up to 106 kbps: Enable fast data transmission with data communication rate up to 106 kbps.
8. UID is provided, and collision detection is realized by reading UID (RID) command: unique identification number (UID) is supported, and collision detection is realized by reading UID (RID) command.
9. Data protection during write operations in BCM20203T512: During write operations, only commands with matching UIDs are responded to, thus protecting the data. At the same time, protection is also provided when multiple tags are present.
10. Data communication is protected by 16-bit CRC integrity check: The reliability of data communication is ensured by a 16-bit CRC integrity check.
11. EEPROM-based user read/write storage area, organized into 8-byte groups: Provides EEPROM-based user read/write storage area, organized into 8-byte groups to facilitate data management.
12. 7-byte Unique Identification Number (UID) for data authentication/anti-replication: Features a 7-byte Unique Identification Number (UID) for data authentication and anti-replication.
13. 480 bytes of user read/write memory: Provides 480 bytes of user read/write memory to meet a variety of data storage needs.
14. 64-bit (8 bytes) OTP memory: It has 64-bit (8 bytes) OTP memory to realize one-time programming of data.
15. All storage areas can be individually and one-time locked through RF commands: Supports individual one-time locking of all storage areas to prevent further modification of data and achieve read-only functionality.

Application scenarios:

1. Identity authentication and storage: It can be used for identity authentication and data storage to ensure data security and reliability.
2. Logistics and inventory management: Suitable for logistics and inventory management to track and monitor goods.
3. Smart payment system: applied to smart payment systems to achieve a convenient and fast payment experience.
4. Event and conference management: Can be used for event and conference management to achieve participant identification and data recording.
5. Product authentication and authenticity identification: Used for product authentication and authenticity identification to prevent counterfeiting and counterfeiting.

Overall, the TOPAZ 512 NFC card provides a flexible and reliable solution for multiple industries through its rich features and wide range of application scenarios.
