Successful Case for Student Safety Management

In order to strengthen student safety management, the South Korean Ministry of Education has been promoting the installation of sensing sensors for children's commuting in primary schools and kindergartens across the country in the past two years. By installing a radio frequency identification (RFID) reader at the entrance of the kindergarten and placing a sensor terminal in the child's backpack, automatic recognition can be achieved during the child's commute.

The core value of UHF RFID technology in school student management lies in achieving seamless passage and efficient attendance. Its general application logic is as follows:

1. Core application mechanism

Sensorless automatic recognition: Using ultra-high frequency readers (with a recognition distance of up to 3-8 meters), students can pass through the school gate wearing electronic school badges or tags without stopping or actively swiping their cards. The system can complete identity verification in just a few seconds and support multiple people passing through at the same time, effectively avoiding congestion during peak commuting hours.

Real time home school linkage: The system automatically records students' arrival and departure times and pushes them to parents in real time through SMS or APP, achieving real-time synchronization of home school information and improving safety management efficiency.

Global data tracking: In addition to school gates, this technology can also be deployed in classrooms, libraries, and other areas to achieve accurate recording and automated attendance of students' on campus trajectories, breaking the information silos of traditional management. ‌‌

2. Technical advantages and scenarios

Conflict prevention capability: The ability to simultaneously identify dozens or even hundreds of tags during peak periods, ensuring accurate data without omission.

Multi functional integration: Modern RFID school logos are evolving from a single identity identifier to intelligent terminals that integrate high-precision positioning, SOS emergency calling, and other functions.

Automated process: Compared to traditional manual check-in or close range card swiping, UHF RFID significantly reduces the burden on teachers, improves traffic efficiency and management service quality.

Successful Case by SeeMore IoT Technology Co., Ltd:

The multi-channel fixed reader/writer FR34A produced by SeeMore IoT uses Impinj E710, the world's leading RF chip, to provide strong guarantees for device reading performance. The core advantages are as follows:

Top notch reading sensitivity: Its receiving sensitivity is as high as -85dBm

Ultra high read rate: able to quickly process a large number of tags. The maximum read rate can reach 1000 tags/second

Powerful scalability: 4 expandable antenna ports are the foundation, while providing rich GPIO interfaces (4 inputs/4 outputs) for easy linkage with external devices such as indicator lights, alarms, etc.

Convenient development and management: Supports standard protocols such as HTTP Post/MQTT, and provides a complete SDK development package for system integration and secondary development. Simultaneously supporting web-based configuration, demo software configuration, remote online upgrade, and other functions.

At present, the FR34A reader has been successfully deployed in multiple primary schools and kindergartens in South Korea, with a running time of over 20000 hours, providing long-term and stable security for tens of thousands of students.
