IN A METHOD FOR EXCHANGE OF DATA BETWEEN A MOBILE COMMUNICATIONS UNIT (10) CARRIED BY A USER (40) AND AT LEAST ONE FIRST COMMUNICATIONS UNIT (20, 21), SECOND COMMUNICATIONS UNIT (30) AND COMPUTER UNIT IT IS PROVIDED THAT THE FIRST COMMUNICATIONS UNIT (20, 21), THE SECOND COMMUNICATIONS UNIT (30) AND THE COMPUTER UNIT ARE POSITIONED AT DIFFERENT LOCATIONS IN AN ENVIRONMENT, PARTICULARLY IN A BUILDING. IN THE METHOD, ESTABLISHING OF CONTACT BETWEEN THE MOBILE COMMUNICATIONS UNIT (10) AND THE FIRST COMMUNICATIONS UNIT (20, 21) TAKES PLACE WHEN THE FIRST COMMUNICATIONS UNIT (20, 21) AND THE MOBILE COMMUNICATIONS UNIT (10) ARE SPACED FROM ANOTHER AT A PREDETERMINED DISTANCE (R), AND A NEAR-FIELD RADIO CONNECTION IS GENERATED WITHIN THIS DISTANCE (R). AFTER EXCHANGE OF DATA BETWEEN THE MOBILE COMMUNICATIONS UNIT (10) AND THE FIRST COMMUNICATIONS UNIT (20. 21) BY MEANS OF THE NEAR-FIELD RADIO CONNECTION THE DATA ARE COMMUNICATED BY THE FIRST COMMUNICATIONS UNIT (20, 21) TO THE COMPUTER UNIT STANDING IN CONNECTION WITH THE FIRST COMMUNICATIONS UNIT (20, 21). IN ADDITION, CONTACT IS ESTABLISHED BETWEEN THE MOBILE COMMUNICATIONS UNIT (10) AND THE SECOND COMMUNICATIONS UNIT (30), WHICH DIFFERS FROM THE FIRST COMMUNICATIONS UNIT (20, 21), WHEN THE SECOND COMMUNICATIONS UNIT (30) AND THE MOBILE COMMUNICATIONS UNIT (10) ARE SPACED FROM ONE ANOTHER AT THE PREDETERMINED DISTANCE (R), WHEREIN A NEAR-FIELD RADIO CONNECTION IS GENERATED WITHIN THIS DISTANCE (R). A DATA EXCHANGE TAKES PLACE BETWEEN THE MOBILE COMMUNICATIONS UNIT (10) AND THE SECOND COMMUNICATIONS UNIT (30) BY MEANS OF THE NEAR-FIELD RADIO CONNECTION.
