Securing your data
All data accessed by our SumUp Card Readers is encrypted instantly and sent securely to our servers. No matter if you’re using a public or private internet connection, your data is safe.
Our servers are housed in a secure facility and all of our employees act in accordance with strict security policies. In addition to these measures, all SumUp software and hardware meets – and in many cases exceeds – the strict security standards outlined by the PCI-DSS (Payment Industry Data Security Standard). PCI-DSS is a policy in the payment industry focusing on credit card transactions, and the policy is supported by all major credit card organisations.
