Comarch SmartCard is a java based cryptographic microprocessor card for the secure storage of sensitive information such as cryptographic keys and passwords. They are chiefly used in PKI (Public Key Architecture) systems and more and more often in banking, where very high security standards, for example for customer transactions, are required.

The card’s security rests on asymmetrical cryptography. The private key used to sign for the transaction never leaves the microprocessor card: it is generated there and there is no way that it can be copied. Only the card’s owner knows the PIN number.
