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 proximity coupling device (100) comprising a contactless interface (107) being configured to inductively transmit a first number of commands towards the integrated circuit, and, after transmitting a respective command, to wait for a reception of a dedicated answer to the respective command from the integrated circuit within a predetermined time interval; and a processor (109) being configured to determine a quality indicator upon the basis of a second number of received dedicated answers to the first number of commands, the quality indicator indicating a quality of an inductive coupling between the contactless interface and the coupling interface of the integrated circuit.
