this is the enshittification that Cory @doctorow@marmot.fr writes about. My partner has a Zettle terminal that was used maybe twice then put away for some time. Upon going back to it, it gives a code 02 error which indicates tampering…which I’m certain hasn’t happened unless the Cat knows more than she’s admitting.
I have managed to get around this tamper lock by plugging an ‘unofficial’ usb C lead in, doing a factory reset, and avoiding the physical power-off button. It now works fine… provided nobody touches the power button.
So by my reckoning, either their tampering alert is triggering for no good reason, because the unit still works - and that’s bad for Zettle’s users, or Zettle’s tamper protection is absolutely trivial to defeat… which is also a massive problem.
