An RFID wristband incorporates identification circuitry (50) which may be of a read only, a read/write, a passive, or an active configuration. The wristband consists of a plurality of laminae (30, 32) which bear components of the RFID circuitry (50) and which encapsulate said cirtuitry upon the securement or adherence of said laminae (30, 32) to each or one another. The wristband is incorporated in an identification system particularly adapted for hospital patient identification and is associated with an RFID reader which generates a magnetic signal requesting identification from the wristband. The wristband is automatically assembled by the utilization of at least two laminae (30, 32) of a polymorphic flexible nature to encapsulate the RFID circuit (50) and includes the utilization of polymeric in conductive components in said circuit. The method of assembling the RFID components (50) with the respective laminae (30, 32) results in the complete isolation of the RFID circuit (50) from contact with deleterious and corrosive substances characteristic of hospital environments.

L'invention concerne un bracelet d'identification par fréquence radioélectrique comprenant un circuit d'identification (50) qui peut être du type lecture seulement, lecture/écriture, à configuration passive ou active. Ce bracelet comprend plusieurs couches stratifiées (30, 32) qui sont dotées de composants de circuit d'identification radiofréquence (RF) (50) et qui encapsulent ledit circuit au moment de la stratification des couches (30, 32). Le bracelet fait partie intégrante d'un système d'identification particulièrement adapté à l'identification des patients d'hôpital, en association avec un lecteur d'identification RF qui produit un signal magnétique demandant au bracelet de fournir l'identification. On assemble automatiquement le bracelet en utilisant au moins deux couches de stratification (30, 32) ayant une nature polymorphe flexible, de manière à encapsuler le circuit d'identification RF (50). Des matériaux polymères sont utilisés dans l'élaboration des composants conducteurs dudit circuit. Le procédé relatif à l'assemblage des composants de ce circuit (50), en combinaison avec les couches respectives susmentionnées (30, 32), permet d'isoler entièrement le circuit (50) de tout contact avec les substances délétères et corrosives qui caractérisent le milieu hospitalier.
