According to my geometry dash subzero, it is possible to buy a used Clover POS system, but it is not recommended. Clover machines are sold with a merchant account contract which cannot be separated from the machine itself. If you buy a used Clover POS from someone who doesn’t give you the merchant account details, the machine is useless. Additionally, Clover designs the architecture of its systems to prevent unauthorized modifications, so altering a used Clover POS is not possible.
