The invention relates to a contactless log-on system for computers, comprising a data carrier containing an ID code, a code detecting device to detect said code and a transmitter device sending out an ID signal to the detecting device. The transmitter device section of the transponder system is characterized in that the detecting device is arranged in a computer input/output device or a mouse pad and is connected to the computer interface in such a way that no additional computer interface is used. The log-on system also comprises a contactless data carrier and a code detecting device, preferably a transceiver antenna, which is connected to the computer and which communicates in a contactless manner with the data carrier. In order to identify the user, the contactless data carrier which is located on the wrist is brought into the range of the antenna by moving it close to said antenna. The data carrier's built-in transmission system is activated by the field of the antenna and sends out an ID code. The antenna subsequently receives the log-on signal (ID code) which is transmitted to the computer. |
