By the title itself it can be implied that the system designed here is very useful for the banks. The security system designed with finger print scanner is aimed to provide high level safety authentication to the clients. These days most of the banks are offering hi-tech safety devices to their customers (those who are having lockers) to increase their confidence. A Finger print scanner provides more safety authentication to the client, increasing their confidence when using the bank services. It uses the features of client’s unique biochemical characteristic fingerprints to pass the authentication for above said application. To prove the concept practically, locker environment must be created, & there by the demo module is constructed with one metal box. This box is build with sliding type of door mechanism. Rock & pinion method is used to open or close the door, this door is driven through a DC motor. The finger print scanner used in this project work has in-built ROM, DSP & RAM. This module when it is operated in master mode user finger prints are scanned, & this data will be stored in ROM. For each finger print, a separate identity is allotted in the system, this is the initial process. After completing this process, the finger print module must be operated in user mode, in this mode of operation the system acquires the fresh data & compares with the previous stored data. If this data is matched, the person will be identified & his/her name will be displayed through monitor interfaced with microcontroller unit. To enhance the safety level further, the processor is designed with additional features such that it appeals the customer through same monitor to prove his/her ID by entering user code through a small keyboard interfaced with controller. When code & finger prints both are matched, then the locker door will be opened automatically. If the code is wrong, the system raises alarm momentarily. The motor used here is having built in with reduction gear mechanism internally there by it is driven through ‘H’ bridge device.
