Etymology of CARD KEY
The term "card key" is derived from the combination of two separate words: "card" and "key".
The word "card" originated from the Greek word "kardia", meaning "heart". In ancient times, people believed that the heart was the center of intelligence, emotions, and important information. The shape of a playing card is similar to the shape of a human heart, which eventually led to the term "card" for a rectangular piece of stiff paper or plastic used for various purposes.
The term "key" has its roots in Old English, derived from the word "cǣg", designating a "device for opening locks". Keys have been utilized since ancient times to unlock doors, chests, and various mechanisms.
