Keep the invoice to send to your insurance provider for reimbursement after ordering a replacement card reader on the SumUp shop.

How your data is secured

All transaction data is immediately encrypted during the payment process, meaning no sensitive data is saved on your card reader. Some basic info may be saved on your phone or tablet.

  • Merchant ID

  • Business name and address

  • Sales history and sales location

None of these details represent a high risk of fraud and is no more detail than could be found on a standard customer receipt.
