Mark the fronts of cards with a pin, thumbtack, ring, etc., in such a way that the thief making such marks can later tell by feel the ranks of the cards. Such marks are applied to the surface of cards and do not tear the cards, merely add indentations that can be felt from the back, as opposed to nailing (see nail), which puts marks in the edges of cards. Also called punch or blister. This is the opposite of prick, in which the thief marks the backs of cards.
