Card tricks are among the easiest magic tricks to perform, and you can learn them online. There are numerous sites featuring free, how-to tricks. Knowing card trick terminology always helps.

Biddle Move:
In your right hand grasp the deck face up between your four fingers and your thumb, with your four fingers on the top edge nearest the audience and your thumb at the inner edge. With your left thumb start sliding cards off the top of the deck. Essentially this is a dragging motion - you drag the card to your left and the rest of the deck to your right. Show the audience each card as it is slid off. Place your little finger underneath your selected card as you slide it off the deck. You should have a few cards in your left hand with your little finger under the top card, and the remainder of the pack in your other hand. As you move to slide the next card to the small pile in your left hand, secretly add the selected card to the bottom of the deck. It becomes easy to hide the move with practice.

Mechanic's Grip:
One of the most often used grips for false dealing where the forefinger curls around the outer right corner of the deck while the other three fingers curl around the side of the deck.

Face/Picture/Court Cards:
Jacks, Queens, Kings

Spot Cards:
Any card from Ace through ten

Palming a Card:
Place a face up card on your right palm so that the top corner makes contact with the top joint of your little finger and the lower corner is against the fleshy part at the base of the thumb. Keep the thumb near the side of the hand and bend the fingers naturally, keeping them close together.

Let your audience watch every move your hands make, and once you're practiced, they will not see a thing.
