Deck checker

Project

To design and build a high-speed playing card verification machine for use in casinos.

The specification required an input stack of up to 8 decks of randomised cards to be checked for missing or duplicated cards within 2 minutes, with 100% accuracy.

The machine needed to print a verification report after each run.

Innovation

The machine was required to learn the features of any casino’s playing cards, with user-definable deck structure for each of several games.

Our contribution

We designed the mechanical parts required to singulate and transfer cards under the machine’s camera to the output delivery tray.

We designed the internal electrics for the motors and other subsystem components.

We developed the vision software, the user interface and the PLC machine control program.

Several prototypes were constructed and trialled, followed by assembly of 100 units. Then we helped transfer manufacture to the client’s manufacturing facilities.
