The invention describes a method for producing chip cards with contactless
and/or contact-type operation having a multilayer card body, an
integrated circuit and at least one coil (2, 21) for data exchange and
for power supply. The coil (2, 21) is applied to one or more layers (11)
of the card body by printing technology, whereby after production of the
printed coil a metal foil (4, 41) is placed over the coil terminals (32,
33) and laminated into the card body, thereby producing the connection
between the contact areas (32, 33) of the printed coil and the metal foil
(4, 41).
