Abstract: Provided are methods, systems, and computer program products for verifying a card image file. A system may include at least one processor programmed or configured to parse a card image file to determine card data represented by the card image file, generate a plurality of simulated payment transactions based on the card data, each simulated payment transaction including simulated transaction data, issue a plurality of commands to the payment device emulator, the plurality of commands based on the simulated transaction data for the plurality of simulated payment transactions, receive a plurality of command responses generated by the payment device emulator based on the plurality of commands, and verify the card image file based on the plurality of command responses and the card data.

Abstract: A method of measuring dimensional changes in a transparent substrate includes forming an array of reference markers on a reference plate, forming an array of substrate markers on the transparent substrate, stacking the reference plate and transparent substrate such that the reference markers and substrate markers overlap, measuring coordinates of the substrate markers relative to coordinates of the reference markers before and after processing the transparent substrate, and determining dimensional changes in the transparent substrate from the difference between the measured relative coordinates of the substrate markers before and after processing the transparent substrate.
