What do I have to do in a warranty case?

If your smart card reader is defective and you wish to take advantage of the warranty, please follow the steps below so that we can process your warranty claim quickly.

In case of software issues, please try first to overcome the issue by re-flashing the firmware, before you continue with the warranty process. A step-by-step guide how to flash the firmware can be found here.

Check whether the warranty claim for the defective device exists

The warranty claim is excluded if

  • the date of purchase is more than 12 months ago
  • the device has undergone external physical damage
  • in case of improper use

Fill in our RMA form

Download the RMA form (English or German) and complete the form. We recommend filling in the document before printing.

Please note that the process can not be proceeded without a completed form.
