Smart card and application

A smart card is the integrated circuit card, also known as microcircuit card. It’s made by inserting a microcircuit into the ISO standard card base and printed by a PVC card printing machine. The smart card is often applied to a reader. They mainly transmit information by electromagnetic waves with specific frequencies.

The smart card is playing a more and more critical role in daily life. But how could we make sure the security to use it with the network?

The COS system of smart card

The operating system for smart card circuit development is called Chip Operating System (COS). The primary function of this COS is to control the information exchange of the smart card and the other machines, to manage the storage in the smart card and to finish different orders within the card.

There are strictly three parts of the COS security system: security status, security attribution and security mechanism. Security status is the current state of the smart card. And security attribution could be said as the conditions to run the smart card. The security mechanism is the two different ways to make identification and confirmation.

The cardholder should insert several secret keys to awake the card’s functioning. Thus, your money would be safer.

Information encryption

Since the smart card has a function of storing contents, it could be used for secret information storage. And you don’t need to worry about the information being stolen because the smart card itself has a process to identify and confirm.

The smart card could be said as a must in modern life, and PVC card printing machine offers convenience in the trend as well. An PVC card printing machine is used to print different kinds of smart cards when your smart card has been inserted with the circuit. With a unique design, they would be more easily distinguished.
