Ⅰ Product introduction -- 2.4G active wrist strap


Name: 2.4G active wrist strap ZJA26
ZJA26 2.4G active electronic tag can have multiple operating frequencies. 2.4GHz can be identified from a distance, making it more secure. 2.4G remote identification tag is a wristband tag card designed and developed mainly for the regional positioning of prison personnel, the regional positioning of elderly people's homes, the identification of hospital patients and other special places. It adopts the RFID 2.45G frequency to cooperate with our PB series medium, long and long distance readers for recognition and induction function, with stable performance and high accuracy. Low power consumption and long life. ic and 125k functions can be added.


Ⅱ Product Features -- 2.4G active wrist strap


1. Read and write speed: compared with the bar code, there is no need for linear alignment scanning, reading and writing speed is faster, and multi-target recognition and motion recognition can be achieved.
2. Security: Encryption algorithm and authentication to ensure data security, prevent link eavesdropping and data cracking, more durable.
3. Special chip, unique serial number, difficult to copy: durability without mechanical failure
4. Label ID: 10 bytes;
5. Label type: read-only;
6. Use time: large battery capacity, long service life;
7. Waterproof grade: IP65;
8. Anti-collision: advanced RF anti-collision technology, can simultaneously identify more than 200 labels/second;
9. High-speed motion recognition: recognition speed up to 60 km/h;
10. High anti-interference: no special requirements for various interference sources on site;
11. Installation: wrist wear;
12. Anti-electromagnetic interference: 10V/m 0.1~1000MHz AM amplitude modulation electromagnetic wave
13. Reliability: waterproof, scalable low frequency 125K and 13.56M frequency included.
14. Targeted: nursing home area, students running timing, other personnel regional positioning and other areas.
