Abstract
A card entry gate has a slot defining several ridges extending longitudinally from the upper and lower surfaces of the slot. A data-bearing card, with an encoded strip and embossed portions, fits between the ridges of the slot when inserted lengthwise in any orientation. The ridges are positioned to avoid the encoded strip and the embossed portions, thereby preventing damage to the card and reducing jitter. The ridges further resist the malicious or accidental insertion of certain coins, odd-shaped cards, and many foreign objects.
