Abstract
Official abstract text for this publication.
A method for determining a transponder type to which an electromagnetic transponder in the field of a terminal belongs, wherein the type is determined based on a difference between a measured value of a piece of information representative of the current in an oscillating circuit of the terminal and a no-load value of this piece of information.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: measuring a single value of an oscillating circuit of a terminal during a first time period, the measured single value providing an indication of current in the oscillating circuit during the first time period; determining a difference between the measured single value and a reference value, the reference value providing an indication of a no-load current in the oscillating circuit of the terminal; and determining a transponder type…
