CA 2518612

A compact disc (1000) coupled to a wireless communication device (1010) comprises the disc with a metalized outer portion (1002), a wireless communication chip (1016) and a pair of tabs (1012,1014). The first tab (1012) may capacitively couple the wireless communication chip, to the metalized portion of the disc. The second tab (1014) may be positioned in an inner portion of the disc with a gap delimited by the metalized portion and the second tab. A slot antenna is thus formed through which the wireless communication device may communicate. Wireless communication chip allows disc to be interrogated and identified for a variety of purposes, including, but not limited to security, advertising and promotion, and issuing of related coupons to customers for subsequent purchases.

Cette invention concerne un disque compact (1000) couplé à un dispositif (1010) de communication sans fil qui comprend le disque comportant une partie externe (1002) métallisée, une puce (1016) de communication sans fil ainsi qu'une paire d'onglets (1012, 1014). Le premier onglet (1012) peut coupler de manière capacitive la puce de communication sans fil à la partie métallisée du disque. Ce second onglet (1014) peut être disposé dans une partie interne du disque, un espace étant délimité par la partie métallisée et le second onglet. Une antenne à fente est ainsi formée, laquelle permet au dispositif de communication sans fil de communiquer. Cette puce de communication sans fil permet au disque d'être interrogé et identifié à diverses fins, telles que la sécurité, la publicité et la promotion et l'émission de coupons associés distribués aux clients pour de prochains achats.
