2. Contactless data transmission and RF field power supply (no battery required): Data transmission is carried out through contactless means, and energy supply can be achieved without batteries.
3. Operating distance: up to 100 mm (depending on antenna geometry and reader configuration): Provides flexible operating distance to adapt to different application scenarios.
4. Operating frequency: 13.56 MHz: Works at an operating frequency of 13.56 MHz to ensure stable communication performance.
5. Data transmission: 106 kbit/s: Provides high-speed data transmission to ensure a fast interactive experience.
6. Data integrity: 16-bit CRC, parity check, bit encoding, bit count: ensure data integrity through multiple verification mechanisms.
7. Collision protection: It has powerful collision protection function and supports identifying multiple cards at the same time.
8. 7-byte serial number (cascade 2 of ISO/IEC 14443-3 standard): Each card has a unique serial number to ensure unique identity.
9. Typical ticket transaction time: < 35 milliseconds: Provide an efficient ticket transaction experience.
10. Fast counting transactions: < 10 milliseconds: suitable for application scenarios that require fast counting.
11. EEPROM: 512 bits, 16 pages, 4 bytes per page: Provides 512 bits of programmable storage space with flexible data management.
12. Programmable read-only locking per page: Provides flexible access control on each page.
13. 32-bit user-defined one-time programmable (OTP) region: Provides additional security options.
14. 384-bit user read-write area (12 pages): Provides large-capacity user data storage.
15. Data retention up to 5 years: Maintain data reliability over a long period of time.
16. Write durability: 10,000 times: It has good write durability and meets the needs of daily use.

Application scenarios:

1. Public transportation system: used in the gate entry and exit of public transportation such as subways and buses to achieve fast passage without paper tickets.
2. Ticketing system: Used in ticketing systems for events, museums, theme parks and other places to achieve a fast and convenient admission experience.
3. Event access control: Suitable for access control management of large-scale events such as concerts and sports competitions, providing efficient admission control.
4. Smart stored-value cards: Stored-value cards used in coffee shops, canteens and other places to achieve convenient payment and accounting.
