A compact disc coupled to a wireless communication device comprises the disc with a metalized outer portion, a wireless communication chip and a pair of tabs. The first tab may capacitively couple the wireless communication chip to the metalized portion of the disc. The second tab 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.
