A portable device (10, 20) comprises at least a control means (14, 24, 34) for receiving command signals and a reader (12, 22, 32). A detection means (18, 28, 38) is connected with the control means (14, 24, 34) and they communicate with each other. Operation of the reader (12, 22, 32) in relation to the object to be identified is controlled through command signals so that at least one of the command signals received by the control means (14, 24, 34) is based on information indicating movement or position received from the detection means (18, 28, 38). The reader (12, 22, 32) is easy to use and quick to operate in its operating environment as no separate actions are required of the user in order to initiate operations. |
