Abstract:
A data carrier for contactless communication with a write/read station, the data carrier comprising:a carrier body;a trough-shaped recess in the carrier body;a module which has been implanted in the recess after it has been formed and which is electrically insulated with respect to an environment of the data carrier,which module comprises a carrier/contact configuration and a chip carried by the carrier/contact configuration and a chip cover of an electrically insulating material which covers the carrier/contact configuration, the chip and two module contacts comprised in the carrier/contact configuration,each module contact being electrically connected to both a chip contact of the chip and to a coil contact of a transmission coil embedded in the data carrier for the purpose of contactless communication,the carrier/contact configuration of the implanted module being a metal lead frame and comprising two side parts and a central part which is substantially coplanar with the two side parts and is situated between the two side parts,the two side parts and the central part being electrically insulated with respect to one another through the chip cover, andthe two side parts forming the two module contacts and the central part carrying the chip, andthe chip cover having a double sided construction in relation to the carrier/contact configuration and comprising a first part situated nearer the environment of the data carrier, a second part which is more remote from the environment of the data carrier and two passages,the module contacts and the coil contacts being electrically connected via the passages by means of an electrically conductive medium.
