PHYSIOLOGICAL RESPONSE PIN ENTRY

摘要

Methods and systems are provided for facilitating the secure entry of a user's PIN for electronic transactions such as merchant checkout, payment authorization, or access authorization. A physiological response of the user can indicate which one of a random sequence of numbers is a number of the user's PIN. For example, the user can blink, wink, or make a subtle facial movement to provide the indication.
