Kindly see the following article for information regarding the warranty SumUp offers on its card readers and what to do should the safety mechanism on your SumUp card reader disable your device.
Your Card Reader is secured from manipulation by technical safety mechanisms. Please handle your card reader with care. Avoid external force or hard impact (for example falling on the ground) to not trigger the mechanism. Once it is triggered, the device will be permanently disabled and can no longer be used.
Should this happen the message “INVALID BPK” (Air) or “Device Blocked” (PIN+) will appear on your card reader’s screen. In this case, your device needs to be replaced. Please contact our Support Team (UK: email@example.com, IE: firstname.lastname@example.org).
SumUp warrants that on delivery and for a period of twelve (12) months from the date of delivery, the card reader shall be free from any material defects in design, material and workmanship in accordance with the applicable statutory provisions.
SumUp shall not be liable to grant any warranty for the card reader in the following cases: (i) If the claim is occurring later than twelve (12) months after the date of delivery; (ii) if the defects are due to improper use of the card reader by the merchant; and (iii) in case of “NTF” (no trouble found).
In addition, the legal stipulations shall apply.
