A universal low cost radio frequency identification (RFID) tag for use with data storage discs includes an RFID chip, e.g., 2.45 GHz mu-RFID chip, coupled to a linear dipole antenna. The antenna length is reduced in length from the expected length for an optimally tuned antenna corresponding to the operating radio frequency of the RFID chip in a free space environment. The antenna is placed in the tag such as to substantially overlap disc hub area and not extend into data area. The combination of the shortened linear dipole antenna and metallization on the disc to which the tag is applied effectively form a complex antenna operational in the RFID chip's frequency range. The RFID tag works on CDs and DVDs with and without substantially metallized hub areas. The RFID tag is less 0.3 mm thick and may include: ring shape, adhesive material, spacing material achieving uniform thickness, a counterbalance provision.
