Why does this matter?  Why do you care which machine the user is
using when they pay?  What about people using internet cafes?  Surely
it's the user who is paying, and you need to securely authenticate the
user.  I don't see that whether they're using a virtual machine or not
is relevant.

I think you're wasting your time.  Any "internel checking method" will
be easily bypassed anyway.
