Technical Examples

A stacked set of playing cards are supported to expose an information bearing portion bearing a first machine-readable indicia and an information bearing portion bearing a second machine-readable indicia, 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 may provide redundancy, or may be related to the first machine-readable indicia to allow the authentication of the playing card.
