The invention relates to a method to use a RIFd (Radio Frequency Identification) - identifier for recognition of roll ware (P), such as a roll of paper or like, whereby a RFId-identifier is being exploited that is to be placed essentially in connection with a core (H) and which consist of a transponder, being formed at least of a RFId-microcircuit and an antenna. For recognition of roll ware, a RFId- identified (1) is being used that is to be placed in connection with the core (H) and that exploits a magnetic field (K1), existing essentially uniformly all over the same in a radial direction (r). The invention relates also to an arrangement applying the method.
L'invention concerne un procédé pour utiliser un identificateur RFId (identification par radiofréquence) pour identifier une marchandise en rouleau (P), telle qu'un rouleau de papier ou similaire. Selon l'invention, l'identificateur RFId utilisé est mis en relation avec un noyau (H) formé d'un transpondeur comportant au moins un microcircuit RFId et une antenne. Pour identifier une marchandise en rouleau, on utilise un identificateur RFId (1), qui est mis en relation avec le noyau (H) et fait appel à un champ magnétique (K1), lequel est sensiblement uniformément réparti sur l'ensemble dans une direction radiale (r). La présente invention porte également sur un dispositif pour réaliser ce procédé.
