Abstract:
A method of producing a contactless chip card comprising the steps of:producing an electrically insulating, planar card body provided with at least one recess on one of its main surfaces, bumps being formed on the base surface of the recess; applying at least one conductor track according to a predetermined conductor track pattern to the one of its main surfaces including the at least one recess, at least one conductor track being applied to surface areas outside of the at least one recess as well as to surface areas within the at least one recess, and the at least one conductor track extending across the bumps and the bottom of the at least one recess; and aligning at least one chip in the at least one recess and contacting the at least one chip with the at least one conductor track extending across the bumps and the bottom of the at least one recess.
