Root Explanation

Keycard → It is formed from "key" (from Old English "cæg", meaning a device used to open locks) and "card" (from Latin "charta", meaning a piece of paper or document). The word "keycard" refers to a card that functions as a key to access secured areas.

Memory Tip

Think of a 'key' that opens locks and a 'card' that is a piece of paper — a keycard is a card that acts like a key to unlock doors.
