Legal analysis: it is legal to handle pos machines, but it is illegal to cash out with pos machines. If a small amount of cash is cashed out, banks will generally not pursue legal responsibility, but will only take measures such as stopping payment, freezing accounts and reducing credit card limits. If a large amount of cash is cashed out and losses are caused to the bank, the bank will take you to court. According to the relevant regulations issued by the Supreme People's Procuratorate, if the cash is cashed by using a point-of-sale terminal (POS machine), if the circumstances are serious, it will be punished as illegal business operation.
