Abstract
Abstract A dual card scanning module announces when the symbols of a face-up standard playing card and a face-down standard playing card achieve a desired combination. The module has a scanner system that illuminates and scans at least a portion of a symbol of the face-up standard playing card and at least a portion of a symbol of the face-down standard playing card and stores the results thereof in a first and second array device, respectively. The module also has a guide to assist in receiving and positioning the cards such that the face-up standard playing card is above and aligned with the face-down standard playing card. When in this position, the symbol portions of the face-up and the face-down standard playing cards can be scanned by the array devices to generate respective scanning results. The module compares the scanning results with a memory storing a plurality of references representing respective symbols of the standard playing cards to determine if the cards have achieved the desired combination.
