A method of producing a data carrier having a carrier card, and a minichip card which can be removed from the carrier card and has an integrated circuit therein, comprising the steps of: forming one of the minichip card and the carrier card with a first material having a first softening temperature; forming the other of the minichip card and the carrier card with a second material having a second softening temperature different from the first softening temperature, in the presence of the card formed in the first step in such a way that the minichip card is held in a receiving window of the carrier card by the latter with a form fit, while avoiding material bonding with the carrier card.
