Why Is My SumUp Card Machine Not Working?
Last updated: March 27, 2025
If your SumUp card reader isn’t working, try these quick fixes:
Check Your Connection
- Ensure you have a stable Wi-Fi or mobile data connection.
- If using Bluetooth, switch it off and on again.
Power & Battery
- Restart your card reader and phone/tablet.
- Charge your card reader – a low battery can cause issues.
Card Issues
- If a card isn’t working, try another or use contactless.
Service or Account Blocks
- Check SumUp’s status page or social media for any system issues.
- If you’ve taken a high number of payments today, SumUp may have placed a security block – contact support if needed.
