An "akıllı kart," or smart card, is a plastic card embedded with a microchip that stores and processes data. These cards can be used for various applications, including payment systems, identification, and access control. They often come with enhanced security features, making them a popular choice for banking and personal identification. Smart cards can be contact-based, requiring insertion into a reader, or contactless, allowing for data transfer through radio frequency. They are widely used in industries such as banking, transportation, and healthcare, providing convenience and security for users in everyday transactions.
