This document summarizes a survey on cardless automated teller machines (ATMs). It discusses using fingerprint authentication and one-time passwords (OTPs) sent via global system for mobile communications (GSM) to allow customers to withdraw cash from an ATM without a debit card. The proposed system uses a fingerprint module and microcontroller to authenticate users via their fingerprint. An OTP is then sent to the user's mobile phone for an additional layer of security. If the fingerprint and OTP match, the user's bank account will open on the ATM machine and allow cash withdrawals. The document compares this approach to existing card-based ATM security and pin-based authentication methods.
