Abstract:
A card reader comprises two rows of electric contacts in the form of elastically deformable contact springs for contacting the electric contact fields of a card inserted into the card reader, wherein the contact springs extend parallel to the card insertion direction and wherein each contact spring comprises a contact section projecting into the card path for contacting one of the contact fields of the card, a connecting section for connecting to a write/read device, an intermediate U-shaped joining section, and a mounting section for mounting the contact spring to the card reader housing, all being formed in one piece with the contact spring. In accordance with the invention, the contact section, the U-shaped joining section and the mounting section are symmetrical relative to the center plane of the contact spring.
