Definitions

  • the invention relates to a method for producing an object with a transponder for contactless data transmission using a carrier film which is provided with at least one semiconductor chip and an antenna coil.
  • Such a method is used, for example, for the production of chip cards.
  • the energy supply and the contactless exchange of data between the semiconductor chip and a transmitter / receiver takes place via the antenna coil.
  • a spiral antenna coil is formed from an electrically conductive layer material on a plastic carrier film (compare, for example, DE 196 09 134 AI and DE 196 04 774 AI).

  • Well-engineered mass production processes are available for a large number of items, which require considerable conversion effort to intervene. This applies, for example, to data carriers such as compact discs or DVDs (digital versatile discs) that have to be manufactured with extreme precision. It therefore requires considerable effort to provide such a data carrier with a transponder.

  • the carrier film can also consist of a plastic that dissolves in alcohol, acetone or a hydrocarbon, such as gasoline. It is only essential that the solvent does not attack the object and also not the antenna coil or the chip. A plastic that only dissolves in an acidic environment is therefore generally less suitable because this can lead to an attack by the thin antenna coil made of metal.
