The project aims in designing a security system which is capable of avoiding transactions from lost ATM card. This system makes use of GSM and RFID technology. The ATM card is going to have a RFID tag inside it. The user of lost ATM card needs to send a predefined format SMS to a phone number given by the bank. The bank authorities continuously monitor the ATM transactions and the lost requests from users. Whenever anyone tries to do transaction from a lost ATM card, the location information of the ATM is sent to the user’s mobile automatically along with horning an alarm system at ATM center. This helps in catching the culprit.   The controlling device of the whole system is a Microcontroller. GSM modem, Buzzer and RFID reader are interfaced to Microcontroller. The Microcontroller Send the messages to the GSM modem and continuously monitors the input from RFID reader. If theft card detected, it automatically sends a predefined message to predefined number along with horning the buzzer. Also, the location information is displayed on the LCD display.  

Features:

1. Advanced lost ATM card locator
2. Location information of ATM card transaction through SMS.
3. Location information of ATM card transaction on LCD display.
