personally i would stay far away from that!! first of all the simple reason that means another 2k get put on the books and theres need, second the cc company sees and they catch on right away! my father one time did that around 15 yrs ago he told me ,not knowing that its an issue and they called him up very upset and theyt wanted to shut the machine down and so on...
Completely irrelevant anecdote. Your father swiped his own card at his own terminal, potentially violating many money laundering laws. The OP was asking about swiping his card at someone else's terminal. Now yes, whomever he swipes the card at would need to declare that he earned that $2K, but that's not the OP's problem.
