An electromagnetic drawer lock system includes a fingerprint sensor module assembly; an outer shell assembly having a front opening, four sides, and a backboard; a drawer having a front, a back, two sides, and a bottom; an electromagnetic lock assembly; a lock catch; a sliding plate; a mechanical lock assembly; a grooved pulley; and a spring paddle assembly. A method of operation includes a user placing a fingerprint on a fingerprint sensor, the sensor capturing a fingerprint image; storing the captured fingerprint image in memory; capturing subsequent fingerprint images; comparing subsequent fingerprint image to images stored in memory; disengaging the electromagnetic lock upon successful recognition of captured fingerprint image; and engaging electromagnetic lock upon successful recognition of captured fingerprint image. A mechanical lock assembly can be used to open and close the drawer if using the fingerprint sensor module assembly is unsuccessful.
