The card machines have a tamper-detection system that detects unauthorised manipulation or attempted fraud using the card machine. If a 'System Tampered' message pops up on the screen of your card machine, it will no longer work. The detection system will trigger when somebody tries to crack open the case, or tampers with the chip reader.
Due to the sensitivity of the detection system, it may trigger if the card machine is dropped, or if it falls. It can also trigger if there is an electrical surge whilst the card machine is charging.
Unfortunately, we're not able to fix a card machine that displays this error message. If your card machine is displaying this error, please get in touch with us to arrange a replacement.
IMPORTANT: Should this occur, we'll arrange for collection of the card machine and assess the cause. If we deem the error to have been triggered due to a manufacturing error or electrical surge, and the card machine is still within its 1-year warranty, we'll replace it. However, please note that if the card machine is returned to Yoco with visible damage marks from being dropped or having fallen, we'll invoice you for the replacement.
