Secure Electronic Transaction Using AADHAAR Based QR Code and Biometric Authentication

Bank services have become more convenient in recent years thanks to electronic banking, but their security is also improving. Hence security in banking services is enhanced using QR code embedded in the aadhaar card and biometric authentication. Using aadhaar number enables the users to access their accounts in multiple banks. Of all the biometrics, fingerprint trait is chosen because of its characteristics like availability, reliability and high accuracy. Finger print recognition system is used for both verification and identification to make the system more secure. In this system, ATM machine can be operated using the aadhaar card instead of ATM card. The in-built camera in the ATM machine will scan the QR code embedded in the aadhaar card and then match it with fingerprint of the user obtained using the biometric sensor. Only after successful authentication, the user will be allowed to perform cash transactions. Hence the need of ATM card for each bank account is completely eliminated by this system. The work of the people as well as the banking sector is simplified. Not only cash withdrawal but also an android application is developed which uses aadhaar number to perform online cash transactions. Hence the system is designed with large number of security features so that a costumer can perform financial transactions without any security issues.
