Only one person had access to the machine.
As mentioned theVIBGYOR keys are all readable. You can see people are even redeeming hole coins.
at some point previously you said "team" used the laptop - if one person only had access then your team is only one person?
and not all the keys were 100% readable I have seen a couple that were not perfectly clear. we did get them figured out but they were not crystal clear as you claim.
