Abstract
The utility model provides a fingerprint identification entrance guard system, which comprises a singlechip, and a relay, a keyboard module, an LCD display module, a real-time clock module, a FLASH memory, an SDRAM (Synchronous Dynamic Random Access Memory) and a first wireless transmission module which are all connected with the singlechip. An electromagnetic lock is connected with the relay, and a PC machine is connected with a second wireless transmission module. A burglar-proof door cannot be opened unless the entrance guarding system is checked by the correct fingerprint, so that the safety of the burglar-proof door is increased. In addition, a user does not need to carry a magnetic card or remember a password, so that the entrance guard system is convenient in use.
