This document discusses replacing traditional ATMs that use magnetic cards and PINs with an ATM that uses iris recognition for identity verification. It notes that current ATMs create environmental waste from paper cards and envelopes and have security issues from stolen cards and PIN cracking. An iris recognition-based ATM would scan the user's iris and match it to a stored iris code, verifying the user only if a match is found. The iris pattern is highly unique and iris recognition has a very low misidentification rate compared to other biometric methods. An iris-scanning ATM would provide more secure identity verification and transactions without generating paper waste.
