An elderly person withdraws money from an ATM at a bus terminal. They are speaking on their cell phone and overlook retrieving the bank card from the card reader. A malicious actor is watching and steals the card. Unfortunately, the card has a small piece of tape with the PIN. The attacker waits a couple of hours after the elderly person has boarded a bus and goes to the ATM to withdraw money. Even though the elderly person has not yet realized their card is missing, the attacker is unsuccessful. Which of the following most likely thwarted the attacker's intent?
Geolocation
Face recognition
Answer explanation
Face recognition likely thwarted the attacker's intent by verifying the identity of the person attempting to withdraw money, preventing unauthorized access despite having the card and PIN.

Geolocation can identify the location of an individual. It can also be used to reduce bank card fraud. When a user makes a transaction at a specific location, the bank can immediately check the location of the user's authorized cell phone. If the cell phone and the bank card are in the same place, then that can be one item of several to validate the legitimacy of the purchase; however, if the cell phone is in a distant location, the transaction may be rejected. Which of the following is NOT a reason a bank transaction may be rejected?
The cell phone is in a distant location
The cell phone is not authorized
The PIN was incorrect
An incorrect quick-response OTP
Answer explanation
The cell phone being in a distant location is a reason for potential rejection, but it is not a definitive reason like an incorrect PIN or OTP. Thus, it is the correct choice as it does not guarantee rejection.
