METHOD, APPARATUS AND ARTICLE EMPLOYING MULTIPLE MACHINE-READABLE INDICIA ON PLAYING CARDS |
摘要 |
A stacked set of playing cards (40) are supported to expose an information bearing portion bearing a first machine-readable indicia (46) and an information bearing portion bearing a second machine-readable indicia (48), such that each of the first and second machine-readable indicia from a number of cards are read by at least one reader. The second machine-readable indicia (48) may provide redundancy, or may be related to the first machine-readable indicia (46) to allow the authentication of the playing card. |
