Are you playing with a full deck?

How the Casino Examiner (JSTAT) was required to put a single deck in sequential order after dealing to blackjack players at Cal Neva in Reno years ago. Pit bosses needed to know if any cards were missing and if cheating was involved by 21 players. Not playing with a full deck cannot be detected by most shuffling machines today who only count the number of cards in a 52 card deck, not the values of the cards. All 4 aces can be replaced with other cards and the shuffling machine will still register 52 cards!!!
