Abstract

See full text

A method for managing the operation of an object capable of contactless communication with a reader, magnetically coupled to the object, includes at least one phase for transmission of information from the object to the reader, including a modulation of the impedance of a load connected across the terminals of the antenna of the object. The method furthermore comprises a control phase that includes an estimation of the distance between the object and the reader and an adjustment of the impedance of the load as a function of the estimated distance.
