The method is suitable for use in a system comprising a client terminal (10) coupled to a server (20) by a first communication medium (50). A user (1) supplies first identification information to the client terminal (10). The supplied first identification information is transmitted over the first communication medium (50) from the client terminal (10) to the server (20). The server verifies that the first identification information corresponds to a stored user profile and then sends a second identification information to the user over a second communication medium (60, 40) such as a GSM network (60) to the user (e.g. to a mobile phone). The user supplies the second identification information to the server (20) via the client terminal (10) and the user's identity is verified at the server according to presentation of the second identification information. The communication media need not be different. The first information may be contained on a token (e.g. card or CD/DVD) or may be memorised or both. The second information may be used as first information in future identification procedures. |
