Method and system of capturing an image of a card

An imaging device for capturing an image of a card having a magnetic stripe, comprising:

• an image sensor for generating image data of the card;
• a memory for storing instructions;
• and
• a processor configured to execute instructions comprising:
• generate data of a first representation of the card from the image data by detecting the magnetic stripe, comprising:
• defining a first rectangle in the image data;
• searching above and below the first rectangle for a consistent color of the magnetic stripe along a width of the first rectangle to detect the magnetic stripe;
• defining a second rectangle in accordance with a specified card ratio value, the second rectangle containing the magnetic stripe;
• and
• cropping along the second rectangle to obtain the first representation;
• generate data of a plurality of second representations of the card via color delta analysis;
• and
• generate data of a third representation of the card by comparing the first and second representations.
