What Are Smart Cards And How Do They Work?
Smart cards are portable, wallet-sized cards with embedded microprocessors and memory that store and process data. They are used for a variety of applications, including identification, authentication, and financial transactions. The microprocessor on the card executes instructions and performs calculations, allowing the card to make decisions and interact with external devices. Smart cards can be contact-based, contactless, or a combination of both, and they communicate with a reader device to exchange data.
The working principle of smart cards involves a combination of hardware and software components. The card’s microprocessor is the brain of the operation, executing instructions and managing data storage and retrieval. The card’s memory stores data, such as user information, encryption keys, and application data. When a smart card is inserted into a reader or comes into proximity with a contactless reader, the card and reader establish a connection, and data is exchanged. This exchange enables a range of applications, from secure authentication and payment processing to data storage and retrieval.
What Are The Different Types Of Smart Cards Available?
There are several types of smart cards available, each designed for specific applications and use cases. These include contact-based smart cards, contactless smart cards, and dual-interface smart cards.
