We recommend installing firmware updates whenever they become available, as it will improve the reliability and speed of your transactions.

Check for available updates

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. On the SumUp App, tap the profile icon in the top corner.

  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.
