The invention relates to a method for producing a support (100) containing at least one electronic device (50), said support comprising at least one fibrous layer (10) of paper or non-woven material including at least 15% mass of synthetic fibres. Said method comprises a step of introducing the electronic device (50), by means of a grip-release tool, at a site on said fibrous layer (10), that does not contain a cavity, by compressing said fibrous layer (10) such that, once the electronic device (50) has been introduced, it is received in the support (100) without generating any increased thickness.
