A system for transmitting data between at least two laser or machine tool apparatuses (2a, 2b), which are not connected to one another via a common network, comprising at least two laser or machine tool apparatuses (2a, 2b) each comprising a communication device with a data interface for setting up a local wireless point-to-point connection, and at least one mobile terminal that is connectable to at least one of the data interfaces and that has a data memory and a communication device for setting up a local wireless point-to-point connection, wherein the one, first apparatus is configured to transmit data from the data interface of the first apparatus via a first local wireless point-to-point connection to the mobile terminal, and the mobile terminal is configured to buffer-store the data transmitted by the first apparatus in the data memory and transmit them via a second local wireless point-to-point connection to the data interface of the second apparatus, characterized in that the apparatuses (2a, 2b) are each configured to set up automatically the point-to-point connection (4a, 4b) between the first apparatus (2a, 2b) and the mobile terminal after entry of the mobile terminal into the reception area of the first apparatus (2a, 2b), and after setting up the point-to-point connection (4a, 4b) between the first apparatus (2a, 2b) and the mobile terminal to automatically transmit the data, and that the mobile terminal is configured to transmit the buffer-stored data via the second local wireless point-to-point connection to the data interface of the second apparatus after termination of the first point-to-point connection later as soon as the mobile terminal has set up a new, second local wireless point-to-point connection with the second apparatus. at least two laser or machine tool apparatuses (2a, 2b) each comprising a communication device with a data interface for setting up a local wireless point-to-point connection, and at least one mobile terminal that is connectable to at least one of the data interfaces and that has a data memory and a communication device for setting up a local wireless point-to-point connection, wherein the one, first apparatus is configured to transmit data from the data interface of the first apparatus via a first local wireless point-to-point connection to the mobile terminal, and the mobile terminal is configured to buffer-store the data transmitted by the first apparatus in the data memory and transmit them via a second local wireless point-to-point connection to the data interface of the second apparatus, characterized in that the apparatuses (2a, 2b) are each configured to set up automatically the point-to-point connection (4a, 4b) between the first apparatus (2a, 2b) and the mobile terminal after entry of the mobile terminal into the reception area of the first apparatus (2a, 2b), and after setting up the point-to-point connection (4a, 4b) between the first apparatus (2a, 2b) and the mobile terminal to automatically transmit the data, and that the mobile terminal is configured to transmit the buffer-stored data via the second local wireless point-to-point connection to the data interface of the second apparatus after termination of the first point-to-point connection later as soon as the mobile terminal has set up a new, second local wireless point-to-point connection with the second apparatus.
