What are different types of smart card technology?

Intelligent card, also called a chip card or integrated circuit card (ICC), may look like a magnetic lane credit card, but it is not. Most smart cards contain a computer chip that contains a microprocessor that, unlike a magnetic lane card, is able to receive and process data. Smart cards are used to identify, hold important records and financial transactions. There are a number of different types of smart card technologies and new types continue to develop because safer systems are sought and new uses are invented for them. The contactless card, also referred to as the close -up card, has a built -in antenna and creates a wireless connection to the card reader.

Contact cards are the most common form of smart card technology. These cards are those with a chip that appears to be a small gold plate. When the contact card is inserted into CAD, CAD makes contact with the chip, allowing information transfer. There are two types of contact cards: memory cards- which may have a straight memory, protected/segmented memory or stored value memory - and CPU/MPU cards. Direct memory cards have the most data storage, but only store data and are basically miniature floppy disks. Protected/segmented memory cards can write down some data that holds, can limit access via password and have the ability to read/write.

Memory cards stored values ​​have permanent safety functions, but all or almost all memory is accepted with the storage of the value or tokens it holds. Using a sample is a phone card. The card can be rechargeable or one -time, depending on the design. CPU/MPU or microprokon cards are capable of processing data. Have the ability to safely identify users and update information.

Java cards are another type of smart card technology. Differs from other intelligent cards in a language they use - more Java rather than a assembly language - and also in usedAPPLETS, small applications. Sun Microsystems®, now part of Oracle®, continues to develop the Java card.
