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:
On the SumUp App, tap the profile icon in the top corner.
Choose "Payment methods".
Now tap on your SumUp card reader. If an update is available, you will see a message informing you to install the update.
