how to design a atm machine by using in lpc2148
ABSTRACT
[
Identification and verification of a person today is a common thing; which may include door-lock system, safe box and vehicle control or even at accessing bank accounts via ATM, etc which is necessary for securing personal information. There is need for improve security in ATM transactions. Due to tremendous increase in the number of criminals and their activities, the ATM has become insecure. ATM systems today use an access
card and PIN for identity verification. The Personal Verification Number (PIN) only not gives good security. The fingerprint is unique and cannot duplicate by others. This system combines the pin verification and fingerprint recognition technology for identification. With fingerprint recognition technology and pin verification we embedded the GSM modem connected to the microcontroller generates the 4 digit one time password and it send to the main user mobile number when the user (main user or nominee user) enrol the fingerprint. The fingerprint of the nominee and the card holder are collected and stored in the database. Every fingerprint which enrols is check by the db. The 4digit one time password should be entered by pressing the keys on the touch screen. After enter all the correct information customer can begin the further transaction. We also
proposed nominees fingerprint identification process while actual card holder unable to do the transactions. The biometric features cannot be replicated; this proposal will go a long way to solve the problem of account safety. Authors design a simple fingerprint recognition system using LPC2148 as a core controller. The system uses SM630 fingerprint scanner to capture fingerprints with its DSP processor and optical sensor. This system can be employed at any application with enhanced security because of the uniqueness of fingerprints. It is convenient due to its low power requirement and portability.
