Smart cards are small, portable devices that integrate a microprocessor or memory chip for data storage and processing. These cards, also known as integrated circuit cards or ICCs, are typically made of plastic and have embedded integrated circuits that can perform various functions. Smart cards come in two main types: contact and contactless.
1).Contact Interface: These cards have a metallic contact pad on the surface, which must physically touch a card reader for communication. The contact points establish a connection between the smart card's chip and the card reader, allowing data to be exchanged.
2).Use Cases: Contact smart cards are commonly used for applications such as credit cards, debit cards, identification cards, and access control cards. They provide a secure way to store and process sensitive information.
1).Contactless Interface: These cards use radio-frequency identification (RFID) or near-field communication (NFC) technology to communicate wirelessly with a card reader. Users can simply place or wave the card near the reader for data transmission.
2).Use Cases: Contactless smart cards are often used for public transportation systems (e.g., transit cards), access control systems, electronic passports, and payment cards (e.g., contactless credit or debit cards).
Smart cards offer several advantages, including enhanced security, portability, and the ability to carry and process diverse types of information. The embedded microprocessor enables secure storage and processing of sensitive data, making them suitable for applications where data integrity and confidentiality are crucial.
