Portable device comprising two cavities for two data carriers which can be used in two different readers, and method of manufacturing the device

摘要

The card has a layer (1) comprising a cavity (11) for receiving a module (3) and circular hole (12), and a breaking line (40) is formed on the card. Another layer (2) comprises a circular hole (22) with a diameter less than the diameter of the hole (12), where a side of the layer (2) is adhered on the side of the layer (1). The hole (12) forms another cavity for receiving an optical disk (4) after the layers are adhered. The thickness of the optical disk is same as the thickness of the layer (1). An independent claim is also included for a method of manufacturing a smart card with two cavities.
