1. A card-reading module for a card-handling apparatus, comprising:
- an illuminator configured to illuminate faces of playing cards with electromagnetic radiation;
a two-dimensional, image-array sensor configured to receive reflected electromagnetic radiation from the faces to generate card face data;
logic circuitry operatively connectable to the sensor, the logic circuitry configured to convert the card face data into binary values; and
a nontransitory memory device operatively connectable to the logic circuitry, the nontransitory memory device storing templates for at least one of a rank and suit of each expected card for comparison to the binary values of the card face data;
wherein the logic circuitry is configured to compare the binary values from generated card face data to the templates to determine at least one of the rank and suit of a given playing card.

Abstract
A device for forming a random set of playing cards comprises a card in-feed area, a shuffling system, a card removal area, and a card reading system located within the device, the card reading system employing a complementary metal-oxide semiconductor (CMOS) sensor and a hardware component, the hardware component capable of converting signals from the CMOS sensor into vector sets and comparing the vector sets to known vectors to determine rank and suit.
