More Information
Summary:The invention relates to a transponder (4.1) which has at least one wake-up unit and at least one data exchange unit for a bidirectional data communication with at least one reading device (4.5), in particular for detecting and/or controlling access authorization to rooms or objects, wherein the reading device automatically transmits signals at least during particular time periods. Because the wake-up unit is permanently ready to receive signals (4.11) for starting data communication between the transponder and the reading device, a device is provided in which a transponder can react to requests of a reading unit without a substantial loss of time in a permanent manner, i.e. not just in short time interval specified by the transponder, and thereby achieves a long service life.
