A smart card reader is a data input device that works and reads smart cards that allow you to store the data on the card and carry out transactions. There is also a card programmer, because it will provide a device for card acceptance (CAD), card terminals, and an interface (IFD) to write. There is only a slight difference between the terminal and the card reader.
A terminal is a standalone device that can process. A player is usually used for the unit that connects to the computer and allows it to operate or to treat, to describe their requirements.
Smart cards are moveable data cards that entail access to a different apparatus to a show device, network or computer. It is important that you place in your smart card into the card reader. occasionally they can with radio frequency (RF) to work.
The function of the chip in the card can be divided into two categories. The chip card can be used as a memory or it could be a microprocessor
It does not follow that the moment a card reader and a contact, your data is immediately opened. Each device is needed to each other to identify by sending and receiving messages. If the information is not shared matches, he takes his job and no further processing. The advantage of this chip technology on ordinary credit cards is the ability to defend against any unauthorized users because it uses very innovative security measures. Chip technology, as it is sometimes called, is the smart card technology is becoming increasingly important in the techno scene and society as a security measure whole.Apart that there are several approaches to protecting your smart card.
The smart card reader provides a path for the application to send and receive commands from the smart card. There are many types of readers available on the ISO (International Organization for Standardization) group was not able to provide a global standard for communication with multiple devices. Therefore, there is no one-size device that fits all approach to communications technology smart card. Examples of different readers are serial, PC card, and models of the standard keyboard. But even with all these decisions on most computers now come with an integrated player in the smart card.
Although there are many readers out there, we must keep in mind that properties that we should all seek, which is desirable to have a card reader. Types of contact card, as is the contact between a reader and a smart card to be physically related.
There are two types of contact and are in contact with the landing and frictional contact.
For the reader, the frictional contact includes touching her part is already solved. The contact wiping the chip and board area, if the card is inserted.
For readers movable landing type of contact is the contact piece. Only to land on the chip after the card is fully inserted. Typically provide card readers, a type of landing a better protection of the contact card uses the kind of friction.
