understanding the types of smart cards – a look at contact cards, combination cards, and contactless cards
Smart card is an integrated circuit chip (ICC) Used to read and process data. They can be used for specific types of identification, bank transactions, telephone prepaid cards, security certifications, credit cards, access to public transport systems, electronic charges, and GSM mobile phone devices. When using a smart card, the identity can be confirmed either by entering a password or by scanning with a reader device. For higher security, biometric technology ( Could be a retina scan for fingers, hands or eyes) Can be used with the card. The most popular types of smart cards include touch cards, contactless cards, and combination cards. They vary in design and have multiple uses. Many smart cards are considered direct memory cards because they can only store data that can be read. There is no data processing capability for this type. Most Integrated circuits are simple, while other integrated circuits can have two chips. The other is called the CPU/MPU Microprocessor card, which has the function of dynamic data processing. They are designed to allocate card memory to separate parts or files assigned to a particular feature or application. Memory allocation and file access are managed by a microprocessor or microprocessor chip (Similar to PC) Own card operating system (COS). Some types of smart cards can use encryption technology for security and data protection purposes. Eight bytes of data can be encrypted into the card. Many of these types of cards have an \"encryption processor\" that can create their own security keys that can be unlocked when used with readers that need their own keys. The contact card is recognized by the gold contact plate located at the top of the card. They are used by inserting them into devices with specially designed slots to read them. The plate produces the energy the reader needs to recognize it. Contact cards are usually used in indoor offices. They are the size of a credit card for cybersecurity, government/student identification, and e-cash. . Another type of smart card is a non-contact card. Many of them are considered CPU/MPU microprocessor cards. The card reader for communication is radio frequency (RFID) An embedded antenna for providing energy to the card as an inductor. Contactless cards can also be direct memory cards that can only be used to read information. Contactless smart card with credit card or token size. Used for electronic passports, student identification, electronic charges, and parking and identification of vehicles. A combined card can use contact/contactless technology in one card and can contain two different types of computer chips. This versatile combination allows the card to be used with different types of readers. They are also known as insurance cards. Combination cards are used for public transportation, network security, and vending machines.
