This document proposes adding fingerprint authentication to ATM security to address weaknesses in traditional PIN-based security. The objective is to provide biometric security through fingerprint scanning. Fingerprints provide highly accurate identification compared to traditional security methods. Advantages include ease of use, inability to forget or lose fingerprints, and standardization. Disadvantages include potential for misidentification, high cost, and difficulties for some users like those with injuries affecting fingerprints. The conclusion is that fingerprint security provides stability, reliability, and ease of use for ATM access.
