What is a Smart Card?

 , updated on
A smart card is a wallet-sized card that has a computer embedded in it for purposes such as identification, authentication, data storage and application processing. These are often used to enhance security by making cards difficult to copy or manipulate.


Smart cards are commonly used for payments, public transport, security ids, government identification such as health cards and to enhance computer and ecommerce security. In many cases, a single card can be used for multiple purposes such as a transit card that can store electronic cash for payments. Smart cards may be contactless whereby they can communicate with devices in close proximity. Alternatively, they may require contact such as being inserted into a slot.
