Bank Locker Security System Using RFID and GSM Technology

Abstract : The main goal of this paper is to design a locker security system using RFID and GSM technology which can be organized in bank, secured offices and homes .In this system only authenticated person can recover money from locker. We can implement a locker security system based on RFID(Radio –frequency identification) and GSM technology containing door locking system using RFID and GSM technology which can activate ,authenticate and validate the user and unlock the door .The main advantage of using passive RFID and GSM is more secured than other systems .This system consists of microcontroller ,RFID reader , GSM modem ,keyboard and LCD .The RFID reader reads the id number from passive tag and sends to the microcontroller where it checks whether it is of valid person or not (from stored data in memory of microcontroller) .If the id number is valid then microcontroller sends the SMS request to the authenticated person’s mobile through GSM, for getting original password to open the bank locker. when the person sends the password to the microcontroller, it will verify the passwords entered by the keyboard (by person present in front of locker) and received from authenticated person’s mobile phone .If these two passwords are matched then locker will be opened otherwise it will remain in locked position .This system is more secured than other systems because two passwords are required for verification and the valid person can type password from his mobile and keypad of locker which should be same as that of stored (initially during account opening) .This system can also create a log containing check-in and check-out of each user along with basic information of user.

 EXISTING SYSTEM :

 ? Current locker system in all banks uses traditional locks, which are heavy, not protective and manually operated. ? Lockers are operated with the help of keys which can be duplicated by professionals. ? Each locker works on two keys, one master-key is with the bank and the other one is with the customer. ? Every time a customer wants to use his/her locker, a record (ledger book) is maintained manually, where the customer has to sign. ? If these safe boxes have the traditional lock system it can be easily picked by burglars.

 DISADVANTAGE :

 ? In this present age, safety has become an essential issue for most of the people especially in the rural and urban areas. ? To resolve this issue, we have proposed a locker system, based on RFID and Password technology. ? The transmitter sends pulses of infrared radiation, while at the same time, the receiver detects any reflections. ? If the receiver does detect a reflection, it means that there is an object at some distance in front of the sensor. ? We have different types of key pads available in market like push button keypad, membrane switch keypad, resistive touch keypad, capacitive touch keypad, etc.

 PROPOSED SYSTEM :

 • In this paper, the RFID reader reads a data from tag and it also send to the microcontroller. • If the card is authentic then display shows the eight digit number of the card read by the microcontroller. Then the authenticated person needs to enter the password by the keypad, if the password is valid then microcontroller sends the SMS to account holder’s mobile number. • Then the person enters the second password to the microcontroller through keypad and compares the passwords entered also the received SMS (OTP). • If these passwords match, the microcontroller provides necessary control signal to open the bank locker. This method is simple and more reliable than other system.

 ADVANTAGE :

 ? Fingerprint scanner is low cost, low power consumption, small size, and excellent performance professional optical technology. ? The passive tag performance depends on the size of the antenna. ? In terms of performance of tags, the shape of the antenna also plays a very important role. The final and last part of the tag is substrate. ? One of the main advantages is that it can be written-erased as many times as possible because it uses FLASH memory technology. ? The conversion of parallel data takes place at transmitting UART side, from a commanding device like a CPU into serial form, transmits it in serial to the receiving UART, which then converts the serial data back into parallel data for the receiving device which may be a CPU or other peripheral device.
