Abstract: An apparatus for monitoring compliance in fraud-prevention associated with a card reader device has a body to be selectively coupled to the card reader device at a coupling region of the card reader device. The body substantially mimics and at least partially overlays the coupling region of the card reader device when coupled to the coupling region. The card reader device has an opening for accepting a card containing electronic data. The body has a card-accepting region associated with the opening that is configured to substantially surround a periphery of the opening when the body is coupled to the card reader device. The card-accepting region permits the card to be at least partially inserted into the opening for reading of the electronic data by the card reader device when the body is coupled to the card reader device. The body further has no capacity to read the electronic data encoded in the machine-readable medium.
