smart card i2c based bank security for lockers

Introduction:
In this ever growing field of electronics everything which is manufactured is too compact and easy to handle and to understand. The world is moving towards the automation, day by day as technology is improving new systems are introduced. Bank locker system is one of the way of giving something new to world of traveling.
Bank lockers are used to keep the money, jwellery, important documents etc.
Bank locker security is most important for the safety of the valuables. There are many cases of bank robbery from the bank lockers. . In today life bank ATM centers are also not safe enough as there has been some cases of money robbery from these ATMS. Taking this in account we have provided a bank locker system which provides safe and user friendly operation.
Existing system:
Most of the bank today uses two keys to open the lockers. If the bank manager wants to open the locker, two keys must be inserted in the locker. One of which belongs to manager and second belongs to another employee of the bank( cashier). The above system has many drawbacks such as
1) Both the bank employees must have to present with the keys to open the locker
2) There is possibility of loosing the key which makes the system insecure
3) The system is unabled to match with today fast moving digital world
4) The keys can be manufactured exactly similar to original ones
Considering all these drawbacks we have designed a bank locker system which is small attempt to compete with the todays digital world
Proposed system:
Bank locker system is specifically designed for the convenience of the bank employee and to provide two level security. A mobile and a smart card can work as a key to open the locker which provides a safe operation. The two techniques used are
1) RFID based technique
2) Smart card technique
The mobile belongs to manager and the smart card belongs to cashier. To open the locker first manager sends a password trough the mobile, if the password is correct then the cashier is asked to type the same password as stored in smart card. If both password gets match the locker will open.
Advantages of proposed work:
1) Two level security system
2) Less time consumption
3) The proposed system is secure and does not allow unauthorized user to access the system
4) No need of bank manager to present physically in bank when locker is to be opened
5) Highly secure system even if smart card and mobile is stolen
