Is there a deposit for the silver dry payment pos machine?

Many POS machines in the market have no deposit. The salesman verbally said that there is no deposit and lied to consumers that they would not charge any fees. In fact, when you turn on the phone, the salesman will ask you to brush the running water of 299 yuan by fraud and other improper means, and then turn on the phone. Then he goes to the second step to open your backstage, then swipe your card, and so on. You will fall into the trap they designed step by step. In this way, your money will be put into the machine for you. Brush at least 5000 yuan every month for 8 months, otherwise the money will not be paid back. I think this should also be called a deposit. Many people actually have the need to use POS machines, but they just can't stand their threats. Why should they swipe their cards as required? The machine recommended by someone who doesn't keep his word may cost you 10000 yuan one day, and you won't get a penny, that is, it shouldn't be called every day, so many people would rather not have this 299 yuan. Anyway, there is not much money, and the loss is still relatively small.
