In this project we propose a design, to add more security to the current digital transaction systems by using biometric and Random finger generation technology. In conventional method, identification is basing on ID cards and static 4 digit password. Whereas in our purposed system, Bankers will collect the customer fingerprints and mobile number at the time of opening the accounts then only customer will be able to acc.ess digital transaction machine. The primary step of this project is to verify current scanned fingerprint with the fingerprint which is registered in the bank at the time of account opening. If the two fingerprints get matched, then a proposed system generate random finger (out of 10 hand fingers) to access the account. For every transaction new random finger will be generate display on the user’s screen thus there will not be fixed finger for every transaction. Thus, finger number will vary during each transaction.
