Abstract: A method for manufacturing a smartcard begins with a smartcard body 2 with two cavity regions 10,12, each region containing two electrical contact pads 16,18 and being suitable for milling to receive an electronics module. A wire 30 continuously connects one contact in the first region to a first contact in the second region, a second contact in the second region, and returns to a second contact in the first region, thus forming a loop 32. The smartcard body can be manufactured by lamination of plastic. A first cavity is milled within either cavity region to a depth (d2, Fig.4B) that exposes the first and second contact pads in that region. A second cavity is milled in the second cavity region to a depth (d1, Fig.4B) that severs the wire between the two contact pads in that region. After milling of the cavities a smartcard IC module or biometric sensor may be installed. An electromagnetic (EM) field may be generated adjacent to the smartcard body to induce a voltage in the wire, and a sensor connected to the milling tool may be used to detect the induced voltage to monitor the depth of the milled cavities. An antenna wire 20 may also be embedded in the laminated card.
