Method of authenticating a personal code of a user of an integrated circuit card
First Claim
1. A method of authenticating a personal code of a user of an integrated circuit card received in a reader fitted with a keypad, communicating with a computer, and capable of accepting at least one type of card, comprising:
- recognizing what type of card is inserted in the reader;
transmitting formatting instructions from the computer to the reader, said instructions corresponding to the recognized type of the card;
transmitting from the computer to the reader an authentication command for use by the integrated circuit card to authenticate the personal code;
verifying that the authentication command received by the reader qualifies as a command for authenticating the personal code inputted via the keypad of the reader;
for a compliant authentication command, putting the reader into a secure mode;
receiving the personal code inputted via the keypad of the reader, and formatting the inputted personal code in accordance with said formatting instructions; and
transmitting the formatted code and the authentication command from the reader to the integrated circuit card.

Abstract
A method of authenticating a personal code of a user of an integrated circuit card received in a reader fitted with a keypad, connected to a computer, and capable of accepting at least one type of card. Formatting instructions are transmitted from the computer to the reader that correspond to the type of the card. A command is sent for authenticating the personal code and the authentication command is verified in the reader. For a qualified authentication command, the reader is put into a secure mode which blocks anyone with fraudulent intentions from intervening in the procedure to obtain the personal code. The personal code is then inputted via the keypad of the reader, formatted for the particular type of card used, and the formatted code and the command for authenticating it are transmitted from the reader to the integrated circuit of the card. The card compares the formatted code with a pre-stored personal code.
