=== Shuffling machines ===
{{Main|Shuffling machine}}
Automatic shuffling machines (ASMs or batch shufflers), that [[randomly]] shuffle decks, interfere with the shuffle tracking variation of card counting by hiding the shuffle. Continuous shuffling machines (CSMs), that partially shuffle used cards back into the "shoe" during play, interfere with card counting. CSMs result in very shallow penetration (number of seen cards), greatly reducing the effectiveness of card counting.
