Indicating a process position for a radio-frequency tag

Abstract

According to an example aspect of the present invention, there is provided a coupling element for indicating a process position of at least one radio frequency identification, RFID, tag, the coupling element comprising: a housing comprising an inside; a shield plate forming a top surface of housing and comprising at least one sensing aperture; for the coupling element configured to generate an electromagnetic field arranged to couple with the at least one RFID tag, and at least one light arranged inside of the housing and configured to illuminate the inside of the housing; wherein the coupling element is configured to process the at least one RFID tag within the sensing aperture such that the at least one RFID tag is coupled to the coupling element via the electromagnetic field, and the at least one light is controlled based on timing of a process of the at least one RFID tag.

Dependencies are inferred from the claim text.
