smartkártyákat

Smartkártyák, also known as integrated circuit cards or ICCs, are physical cards with embedded microchips that can store and process information. These chips can be programmed to perform various functions, making smart cards versatile and secure. Commonly made from plastic, they resemble credit cards in size and shape.

The primary advantage of smart cards lies in their security. The embedded microchip uses cryptographic techniques to protect stored data and authenticate users. This makes them more secure than traditional magnetic stripe cards, which are prone to skimming. Smart cards are used in a wide range of applications. They are prevalent in payment systems, such as credit and debit cards, enabling secure transactions. In telecommunications, they are used for SIM cards in mobile phones to identify and authenticate users on a network. Access control is another significant area, with smart cards used for building entry, secure computer login, and employee identification. They are also employed in transportation for ticketing systems and in healthcare for storing patient records. The data stored on a smart card can range from simple identification numbers to complex encrypted information, depending on the specific application.
