<p>A contactless data carrier suitable for use as a smart card, comprises a laminated structure consisting of core films 10,11 having a circular opening 12 for receiving a package 1 for containing an integrated circuit. The package is circular in plan and comprises equal halves 32, 33 so it is symmetrical about a plane passing through its centre. The halves are bevelled along their edges and allow the package to be received in the opening as a press-fit and located symmetrically with respect to the films 10,11. The package has conductive leads 4.1 which extend into a region between the core films for contacting an antenna. The antenna may be disposed on a further film located between the core film or take the form of a flat coil of wire located between the films 10,11 or be integrated with one of the films 10, 11. Covering films (not shown) are provided to at least partially enclose and to protect the whole package.</p> |
