How Student IDs With RFID Work
Student ID cards with RFID rely on electromagnetic fields to automatically identify a student and track their movements. The chip in the student ID cards has some memory and processing capacity. It draws powers from a nearby RFID reader, which transmits radio signals within a specific range.
RFID systems comprise three components: a transponder, a transceiver and a scanning antenna. Educational institutions that use student IDs with RFID have RFID antennas around the school campus to track the ID cards and determine when students access certain locations, such as the library, cafeteria or school campus in general.
A well-planned grid of cables for power and communication connects all the antennas and RFID readers to a power source. A central computer receives, stores and processes all the data from the RFID readers to which it is connected. This computer is linked to the student information system, which the educational institution can use to manage the data for security and administrative purposes.
MIFARE DESFire EV2 is one of the most commonly used chips in student ID cards. It is Common Criteria EAL5+ security certification, meanings it meets the same security standards for the smart card industry. This smart card chip easily integrates with existing school security technology. It supports several security features, such as the latest encryption and authentication protocols.
