Study and Design of Deposit Box Based on Fingerprint Recognition

In this paper, we design a fingerprint recognition deposit box system based on M04 fingerprint recognition module and 89C52 single-chip microcomputer, making use of the uniqueness and convenience of fingerprint. This system consists of hardware design and software design. We adopt modular idea for the hardware design, and there are five function modules: single-chip microcomputer module, fingerprint module, storage module, I/O control module and voice module. For the software design, we make the system flowchart and application software with the assembler language of MCS-51 single-chip microcomputer. By the direct interruption control, TNT0 and INT1, the two external interrupts of 89C52 single-chip microcomputer, will trigger corresponding operations, and then the bags can be deposited and taken back safely, expediently and quickly.
