Use fingerprints, passwords or other ways to replace the key, users no longer need to worry about forgetting to bring the key when they go out or accidentally losing the key, and standing outside the door, or standing outside the door when they go home shopping with a big bag for example, finding a key, this provides a lot of convenience for daily life.This design is composed of the core circuit board of STM32F103C8T6 single chip microcomputer, biological fingerprint identification circuit, film matrix keyboard circuit, RFID-RC522 radio frequency induction circuit, LCD12864 liquid crystal display circuit and buzzer module circuit. Support fingerprint, NFC, password and proximity card to unlock. The system operation interface is disp...
