Explanation
RFID (Radio Frequency Identification) uses radio waves to wirelessly read data from a chip embedded in a card or badge. Badge readers in physical access control systems are the most direct and common application of RFID - employees tap or wave their RFID-enabled ID badge near the reader to authenticate and unlock a door or system. Biometric locks use physiological traits like fingerprints or retinal scans. Hardware tokens generate time-based one-time codes. Control rosters are paper-based access lists. Only badge readers rely on RFID as their core operating technology.
