1. Suitable for long-term wear: The electronic wristband is made of medical soft material, which will not cause allergies if it is in contact with the skin for a long time. At the same time, the softer texture can avoid the discomfort caused by long-term wearing by detainees.
2. Strict waterproof treatment: Due to the daily work of prisoners and the inevitable contact with water in life, in order to prevent damage to the internal circuit caused by moisture, a wristband.
3. Anti-private disassembly design: The electronic wristband adopts a unique anti-detachment design. Without special tools, detainees cannot take off the wristband without permission. At the same time, if the detainee forcibly cuts or destroys the electronic wristband, the electronic wristband will automatically issue an alarm signal.
4. Low power consumption: The electronic wristband uses a special data interaction mechanism to greatly extend battery life. In charging mode, the battery life on a full charge is not less than 150 days. In non-charge mode, the battery life is not less than 300 days.
5. Low battery reminder: When the power of the electronic wristband is lower than the alert value, the system actively prompts the insufficient battery information.
卡通融合： 一 电子腕带中可以附属一张IC卡，在卡上可以存储部分在押人员相关信息，为实现在押人员一卡通管理提供硬件基础。 6. One card integration: An IC card can be attached to an electronic wristband, and some information about detainees can be stored on the card, providing a hardware foundation for the detainees' one card management.
