3-Track Magnetic Stripe Reader and OCR-Reader

This device contains two independent readers: The OCR modul for machine readable documents (e.g. ID cards, passports) and a magnetic card reader for recording credit cards or access cards. The ergonomic design has been selected to achieve optimum adaptation to human work movement.

Both internal readers operate bidirectionally, so that documents and cards can be fed through the reader in both directions. This means that the input device is ergonomic and easy-to-use for both right and left- handed users.

The option to install this device flush-mounted into the user's furniture fittings completes the outstanding ergonomic design. For all applications which require clear, rapid recording of machine- readable data from documents, this module offers a practical and costeffective solution.
