Abstract

A method and apparatus for checking and controlling access to mobile telephones, computers or related devices with regard to transactions and to the handling of information, respectively. The user is provided with a user-specific identification tag that communicates with the mobile telephone or computer via a radio wave transmitter/receive unit that has a short range. The identification tag exchanges with the telephone or the computer identity information carried by the identification tag to ratify identification of the user, and to thereby control access to the telephone or computer.

Claims

1. A method for checking and controlling access to electronic devices such as mobile telephones, computers, or corresponding devices with regard to transactions and handling of information, respectively, said method comprising the steps of:

providing a user with a user-specific identification tag having user identity information and including a radio wave transponder which retransmits an incoming radio signal back to a radio wave transmitter/receiver unit associated with the electronic device that transmitted said incoming signal, wherein a radio wave transmitter/receiver unit of the identification tag has a predetermined short transmitting range;

communicating via Bluetooth wireless transmission between the identification tag and the electronic device in a predetermined communications area adjacent to the electronic device; and

exchanging between the identification tag and the electronic device identity information carried by the identification tag to ratify identification of the user, wherein one or more functions of the electronic device can only be performed subsequent to a given identification tag having been identified and accepted by the electronic device giving access to said functions.

2. A method according to claim 1, including the step of ascertaining at least at uniform short time intervals whether or not the identification tag is situated within the predetermined communications area determined by said range.

3. A method according to claim 2, including the step of terminating access to the electronic device when the identification tag leaves said predetermined communications area.

4. A method according to claim 1, wherein the predetermined range is less than about 10 meters.

5. Apparatus for checking and controlling access to electronic devices such as mobile telephones, computers, or corresponding devices with regard to transactions and handling of information, respectively, said apparatus comprising:

a user-specific identification tag having user identity information and including a transponder which retransmits an incoming radio signal back to a radio wave transmitter/receiver unit associated with the electronic device that transmitted said incoming signal, wherein the identification tag has a predetermined short transmitting range in that the identification tag communicates according to Bluetooth wireless transmission with said electronic device via radio waves in an area adjacent to the electronic device, wherein the identification tag exchanges with the electronic device information carried by the identification tag; and

wherein the user is considered to have been identified by such information exchange and wherein one or more functions of the electronic device can only be carried out subsequent to a given identification tag having been identified and accepted by the electronic device giving access to said functions.

6. Apparatus according to claim 5, wherein the electronic device ascertains at least at uniform short time intervals whether or not the identification tag is situated within a the predetermined communications area determined by said range.

7. Apparatus according to claim 5, wherein access to the electronic device is terminated when the identification tag leaves said predetermined communications area.

8. Apparatus according to claim 7, wherein the predetermined range is less than about 10 metres.
