Abstract

A playing card delivery shoe is used in the play of the casino table card game of baccarat or blackjack or any game where cards are pulled one at a time from the shoe. The apparatus comprises a reader or an imager that scans lines bisecting the image at spaced intervals. The scanning occurs on playing cards in at least the region where suit and rank symbols are provided. The scanner output is a series of voltages that are converted to binary information. This binary information is compared to stored binary information to determine rank and suit. The upper surface of the output end of the shoe contains a partial barrier for cards being scanned. The partial barrier has an elevated surface and limits a size of a pathway so that only one card can be removed at a time.
