GSM BASED SMART INFORMATION SYSTEM FOR LOST ATM CARD

Abstract

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 will have 
an RFID tag inside it. The user of lost ATM card 
need 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 reads the messages from the 
GSM modem and continuously monitors the 
input from RFID reader. If both the inputs are 
same, it automatically sends a predefined 
message to predefined number along with siren 
at the buzzer. Also, the location information is 
displayed on the LCD display.
