A radio frequency identification reader (RFID reader) is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to transfer data from the tag to a reader.
RFID application is very popular in access and attendance control for convenience and security purposes. With proximity reader (sensor and standalone), access and security management is possible with proximity card and key chain. Information such as attendance, access data tracking and monitoring is stored and can be printed for analysis.
