Our team is constantly working on making our card readers even more reliable and faster. Therefore, from time to time updates are available for the firmware of the card reader. Please install a firmware update whenever available, as it will improve the reliability and speed of your transactions.

If you do a transaction and the connection between the terminal and app is set up, there is an automatic check if a firmware update is available.

In addition, you can check the status yourself by doing the following:

  1. Open the settings Default.pngin the SumUp App.
  2. Choose "Payment methods".
  3. Now tap on your SumUp card reader. If an update is available, you will see a message informing you to install the update.
