Our team is constantly working on making the card reader 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 account area in the SumUp App (iOS: click on “Account” top left corner, Android: click on menu symbol in the top left corner).
  2. Choose “Payment Methods”/ “Choose card reader”
  3. Now tap on the card reader symbol and connect the terminal. If an update is available, you will see a message informing you to install the update.
