Definition

Noun: A smart card is a small, portable device, typically the size and shape of a credit card, that contains an embedded integrated circuit chip. This microprocessor chip can process, store, and protect data, enabling the card to perform secure operations, such as authentication, data storage, and financial transactions.

Usage

A smart card is used as a secure token for identification and transactions. It requires a card reader to access the data and functions stored on its chip. - The new employee was issued a smart card to access the secure building and log into her computer. - Many modern credit cards in Europe are smart cards, which are more secure than cards with only a magnetic stripe.

Advanced Usage
