Pegging
Pegging is a cheater's technique of marking cards with a fingernail or a device, so that the marks can be found later. It is the same as pricking.
The simple explanation
A cheat marks cards by pressing a nail or tool into them. He can then recognize the cards by touch or sight.
A closer look
Pegging, pricking, punctuating and nailing are different names for similar marking methods. Casinos use new decks and cameras to prevent them. If you find marks, tell the floor at once.
A practical example
A player finds small dents on the backs of cards and tells the floor.
