Setup of the SumUp EMV card reader

General handling

• We can ensure a functionality of the device with a temperature between -10°C and +45°C. Therefore we recommend not to leave your card reader over long time, e.g. in your car, in midsummer or winter.

• Even when you don’t use your card reader on a regular basis, we recommend to charge it once per month.

• The card reader is designed with security sensors to protect it from manipulation and tampering. For this reason, you should always handle your card reader with great care. Be sure to avoid using the device with force or impact (including dropping it on the ground or knocking it across the table) to prevent an automatic security lock being enabled. Once this is triggered, the card reader is permanently locked and cannot be used.

• Please always ensure you are not using the card reader on metal or magnetic surfaces. The device has a security feature that prevents any unauthorised reading of magnetic card strips on credit and debit cards. When the device is placed on or near a metal surface this can cause the card reader to automatically decline the payment.
