Coded playing cards

A playing card with an identification code for automatic detection of an index and a value of the card, wherein:

• the identification code is provided mutually symmetrically along each of opposed, long sides of the card,
• the identification code along each of the long sides of the card includes six code fields (“a”-“f”) of substantially the same size that occupy in combination at least one fifth of a length of the card,
• the code fields are filled in a manner that is characteristic to a specific card,
• at least one first code field of the code fields is filled with a substance that fluoresces upon exposure to UV illumination and at least one second code field of the code fields fluoresces less upon exposure to the UV illumination than the at least one first code field, and
• the code fields are arranged such that:
• the code field “a” of the identification code on one of the long sides of the card and the code field “f” of the identification code on the other one of the long sides of the card are arranged opposite to each other on either side of a longitudinal center axis of the card,
• the code field “b” of the identification code on one of the long sides of the card and the code field “e” of the identification code on the other one of the long sides of the card are arranged opposite to each other on either side of the longitudinal center axis of the card, and
• the code field “c” of the identification code on one of the long sides of the card and the code field “d” of the identification code on the other one of the long sides of the card are arranged opposite to each other on either side of the longitudinal center axis of the card.
