The invention discloses a password type card swiping lock system which is formed by a power source module, a central processing unit (CPU) control module, an identity (ID) card receiving module, a lock sensor module, a drive unlocking module, an acousto-optic prompt module and an alarming module. The power source module converts 220v alternating current into 12v direct current and 5v direct current which are required by the system through a built-in transformer. The CPU control module controls and receives the ID card receiving module, and performs corresponding processing and releases a microoperation signal according to an instruction of the received information. The lock sensor module transmits door state information to the CPU control module to perform information processing and control. The drive unlocking module opens the door after receiving a control order signal sent by the CPU control module. The acousto-optic prompt module and the alarming module are information prompt devices and perform corresponding processing and control orderly aiming at different applications according to the microoperation signal sent by the CPU control module. By means of the password type card swiping lock system, users can utilize the exiting ID cards to cancel lost or obsolete ID cards, encryption can be performed by means of the ID cards, and security is enhanced.
