Abstract: A handheld light-emitting device having a housing and a radio module is described, the radio module being designed to receive information from at least one external interface and/or transmit it to at least one external interface. Provision is made that the radio module is disposed in the housing of the handheld light-emitting device.

Abstract: A hand-held power tool, in particular an electric hand tool, includes an identification module and a housing. The identification module includes a transponder having at least one data store configured to store identification information and a radio module configured to transmit the identification data. The identification module is integrated into the housing.

Abstract: A method for operating a mobile device with a communication module and an accumulator, in particular a hand-held power tool, includes powering the communication module via electricity from the accumulator. The communication module enables wireless communication, and is powered only temporarily at least for transmitting data.

Abstract: An identification module for mobile objects, in particular hand-held power tools, includes a housing, a transponder, and a stored energy source. The housing has a mechanism configured to arrange and/or fasten the identification module to a mobile device. The transponder has a data memory and a radio module. The memory is configured to store identification data, and the radio module is configured to send the identification data. The stored energy source is configured to power the transponder. The housing has a chamber, an opening into the chamber, and a lid configured to close the opening. The opening is configured so as to enable the stored energy source to be removably arranged in the chamber via the opening.
