Claim 12:
13. A method, comprising:
obtaining images captured adjacent to or overhead of a card reader slot for a card reader module associated with a transaction terminal;
determining whether a card slot tampering event is to be raised for a user present at the transaction terminal based on analysis of hands of the user in the images relative to the card reader slot; and
providing an alert when the card slot tampering event is raised causing the transaction terminal to be non-operational for transactions processed on the transaction terminal;
wherein determining further includes passing the images to a first Machine-Learning Model (MLM) that outputs bounding boxes for the hands in the images and passing the images and the bounding boxes to a second MLM that outputs object identifiers for any known object in the user's hands and any unknown object in the user's hands.
