This method involves analyzing the oscillatory behavior in the NFC reader device, after the RF field transmitted by the reader has been switched off, using a decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components. The method involves predetermining the decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components, e.g. weighted oscillation components, wherein each one of said M superimposed components is defined by a predetermined superimposition function, which in turn is determined by an associated set of characteristic parameters, and storing, e.g. in a database that is accessible for the P&E unit, an indication of the decomposition scheme and the M predetermined superimposition functions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Classification of objects in the proximity of an NFC reader device","description":"Disclosed is a method for determining a type of an object arranged in a radio frequency, RF, field transmitted by an NFC reader device.
