Abstract
The invention relates to a card-shaped data carrier comprising a card body (1) having an antenna (3), and a chip module (2) containing an integrated circuit (10) and inserted into a gap (5) in the card body (1). The electric connection between the antenna (3) and the chip module (2) is effected via depressions (11) in the terminals (4) of the antenna (3). For producing the inventive data carrier one provides the card body (1), in which the antenna (3) is at least partly embedded, with a gap (5). The terminals (4) of the antenna (3) are exposed by removing the superjacent card material whereby part of the material forming the terminals (4) is also removed. The chip module (2) is inserted into the gap (5) and for example glued to the card body (1) with a thermally activable adhesive (6), an electric connection being formed between the chip module (2) and the antenna (3) for example by means of a conductive adhesive (7) previously applied to the exposed terminals (4) of the antenna (3). In the preferred embodiment the material removal on the terminals (4) of the antenna (3) is effected such that a bevel arises.
