Abstract

A chip card reader has a fixed frame in which a movable carriage is mounted. The carriage supports contact means for reading the semiconductor chip in a chip card. The electrical connection between the contact means and the rest of the electrical circuitry is established by a ribbon conductor which is formed in a fanfold configuration. This reduces the likelihood of breakage and increases the service life of the chip card reader.
