Abstract
The invention relates to a mobile proximity coupling device (100) for inductive coupling with an integrated circuit of a proximity object, the integrated circuit comprising a coupling interface for inductive coupling, the mobile proximity coupling device (100) comprising a contactless interface (107) for inductive coupling with the coupling interface of the integrated circuit; a processor (109) for determining a quality indicator indicating a quality of the inductive coupling; and a display (111) for displaying a desired change of position of the mobile proximity coupling device relatively to the proximity object if the quality indicator indicates an insufficient quality of the inductive coupling.
