Design of Embedded Based Dual Identification ATM Card Security System

Over 900 cases have been registered related Automated Teller Machine (ATM) card frauds till Sept-2018 where Indian banks lost around Rs. 109.75 Cr. This paper aims to prevent the crime related to ATM card frauds and secure transaction. In this paper, two options are included like One Time Password (OTP) and Fingerprint detection for a successful transaction. The user can use any of the two options mentioned above for ATM transactions. We know that the OTP is valid for only one transaction and a specific duration. Thus, the Global System for Mobile (GSM) is used for the generation of OTP and that OTP is sent to the mobile number to which the bank account is linked. In case, if the user does not have the mobile to which the bank account is linked or else the mobile is switched off or network problem the second option of fingerprint authentication can be used. The fingerprint of the user must be linked with the bank account so that the unique pattern of the fingerprint can be used to make a successful transaction. Hence this project will increase security and add privacy by making use of biomedical authentication that is fingerprint pattern detection. Therefore this added feature helps to reduce the crimes related to ATM cards.
