No sensitive card data is stored on any mobile device while processing payments with SumUp. Because of that, all data will remain unaffected if your card reader gets stolen.

Due to the fact that the SumUp device encrypts all the information as it reads the card, no unencrypted data is ever stored on the device during the transaction process.

Our team works hard for your security, and as such we constantly update all systems to ensure we provide the appropriate levels of protection. Furthermore, we take all preventive measures necessary to keep our systems secure and our clients’ data safe. We have qualified internal and external teams to test our security systems on a regular basis, and sensitive data is strictly controlled at all times.

If your SumUp Card Reader got stolen, please order a new one via the shop in your SumUp Account at and send the invoice to your insurance company.
