ABSTRACT:
A chip card including a card base with a recess. A circuit support and a microcircuit is arranged on a circuit support surface which faces an interior of the recess and is spaced from the recess bottom. A raised portion is formed on the recess bottom and spaced from a cover section so as to divide the recess into two regions bounded by the recess bottom, the cover section and the raised portion. The first region is completely filled with an encapsulant and the second region is partly filled with the encapsulant.
