Smart Card simultaneously having two read/write mode matrixes and method for producing same

A manufacturing method of a smart card with two read-write modes, comprising steps of:

• (1) embedding:
• embedding an antenna on a back side or a front side of an antenna layer, and setting a wire end of the antenna in an area corresponding to circuit contact points of a chip module circuit;
• (2) laminating:
• after completing embedding on the antenna layer, add bedding sheets, printed sheets and protection films respectively above and underneath the antenna layer, then laminating to obtain a card base carrier;
• (3) cutting card and slotting:
• cutting the card from the treated whole-sheet card base carrier to obtain a card base;
• milling slot in the obtained card base:
• firstly milling a slot B5 on a location for insetting of a chip module, with a depth thereof equaling to a thickness of a chip module lead frame, then milling a slot B6 in a center of the slot B5;
• adopting a milling cutter with a special sensor for milling the location;
• while milling the slot using the milling cutter, real-time detecting whether to mill to an embedded cooper wire layer;
• when the wire end of the embedded wire is touched, immediately stopping by a preset program and memorizing a value;
• then milling slots B3 on locations for elastic devices, depths of the B3 slots are decided by the memorized value;
• and
• (4) encapsulating:
• at first insetting the elastic devices into the slots B3 and connecting with the wire ends of the antenna, then insetting the chip module circuit into the slot B5 and the slot B6 at the location of the elastic conductive device corresponding to the circuit contact points, then finalizing a shape.
