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.
