Portable data carrier for mobile phone systems, with detachable mini chip card having perforated break line for further miniaturization of mini chip card

摘要

Card body (1) contains mini chip card/plug-in (2) connected to card by bridges (6) formed so plug-in can easily be broken off from card. Plug-in has further perforated break line (5), for further miniaturization of plug-in. Perforated line is more stable than bridges, so that it does not break when plug-in of format ID-000 is removed from card body.
