1, look at the payment license plate,
At present, POS machines are divided into primary cleaning machines and secondary cleaning machines. The main difference lies in the credit card settlement link. After UnionPay initiates the sorting machine, the bank will directly settle the money to the merchant account (collection account); Many POS machines in Qing Er are owned by Qing Er Company, and there are no payment licenses. These are all payment channels borrowed from Yiqing Company. These Qing Er companies will run away at any time, or be closed down or banned by supervision, and there are great hidden dangers in the safety of funds. Do not use the second washing machine. Therefore, when handling pos machines, you must choose a regular central bank to clear the machine and inquire about the payment license. Only payment companies licensed by the central bank can engage in payment business.
2. See if the credit card rate is in line with the market, and don't covet low rates.
Too low a rate seems to take advantage, and swiping a card will definitely skip the code, resulting in the reduction of credit cards and the consequences of card closure, which is not worth the candle. As we all know, wool comes from sheep, so from the point of view of raising cards, we suggest that you don't use machines with low rates, which is not conducive to cash withdrawal by credit cards. There is no free lunch! We can't blindly pursue low rates without considering the consequences.
3. See if there are any local businesses, and skip the code after swiping the card.
Many merchants with hand brushes or POS machines can't locate provinces or cities, and every time they swipe their cards, they jump across the country. If the cardholder has multiple transactions in a short period of time, and the merchants given by the system are in Guangzhou, Shanghai and Xi 'an for a period of time, it will inevitably trigger the bank's risk control system. In order to prevent risks, the bank will freeze or seal the card.
4. After-sales service
Many people only pay attention to whether the price is cheap and the rate is low enough, but completely ignore the after-sales. Pos machines are not sold at one time. In the process of use, they will encounter many incurable diseases more or less. The most serious thing is that the transaction funds are controlled by the risk of UnionPay or other reasons. If the funds are frozen, they must find a superior service provider, who will submit them to the acquiring institution for unfreezing. The official customer service can only solve some inquiry problems, but can't solve written problems. Find a reliable one.
