Abstract
The invention discloses a method and a system of upgrading firmware of a card reader. In the method, a card reader is connected to an IC card; the card reader determines whether the IC card is an IC card for upgrading, if it is, the card reader makes one-way or mutual authentication with the IC card; after a successful authentication, the card reader acquires files for upgrading the firmware of the card reader. The system includes a card reader and an IC card. The firmware of card reader is upgraded in the invention by acquiring the files for upgrading from an IC card in which the files for upgrading are pre-stored. The invention improves the efficiency of upgrading the card reader and also improves the security of the upgrading by the authentication between the card reader and the IC card.
