A smart card is a pocket-sized card, generally made of plastic, and is embedded with integrated circuits, also known as microchips. Smart cards are used for security purposes for authentication, identification, data storage, and application processing. They are widely used in sectors such as BFSI, Government, Transportation, Healthcare, and Defense. These cards are broadly classified into two types: contact-based and contactless. Contact-based smart cards have a contact area of approximately 1 square cm. These cards are used by inserting into a smart card reader. On the other hand, contactless smart cards are used by employing radio frequency between cards and a reader, which needs no physical insertion of the cards. Therefore, contactless smart cards have faster applications and are more user-friendly than contact-based smart cards.
