Understanding card labeling basics

Card marking is a technique used by fraudsters to identify cards without seeing their faces. By marking cards in a special way, cheaters can predict upcoming cards, which gives them a clear advantage over unsuspecting opponents.

Common Methods Used

  • Coating: This involves applying a substance, usually a special ink or paste, to the card. The sign is usually invisible to the naked eye, but can be seen with special glasses or under certain lighting conditions.
  • Nail Incision: A small, almost imperceptible incision is made on the card with a fingernail. Different nicknames can stand for different cards.
  • Edge Sorting: This is where the cheat uses a tiny asymmetry on the back of the cards. By turning certain cards over, they can determine their meaning by observing these imperfections.
  • Crimping: This method involves bending the card very lightly, often with gentle thumb pressure, to create a tiny protrusion or bend. Crimping allows you to identify the card by touch or visually.
