That is, UnionPay risk screening is an action of UnionPay to conduct a transaction investigation or freeze funds for merchants suspected of trading risks. Credit card swiping in different places for a short time, abnormal consumption habits of cardholders and bad credit records may all cause risk control of POS machines.
This shows that there is something wrong with the user's payment environment, and there is generally illegal operation or the risk of theft. In order to protect users' accounts, UnionPay temporarily controls risks. For example, users often change devices to log in, or log in on new devices, and there will be one-day transactions or large transactions, which will lead to this situation. Users can consult UnionPay customer service, wait for the risk specialist to call back, check their own information and card information, and generally call back the same day to release the risk control.
The risk of UnionPay is blocked for the following reasons:
1. The merchant has a problem. If the merchant often uses China UnionPay Express to pay by credit card, it may be blacklisted by UnionPay. For example, some personal pos supports China UnionPay quick scan code, and many merchants have been blacklisted by UnionPay, which will remind users that the risk is blocked when paying.
2. mention the existing. If users use China UnionPay Express to pay by credit card, it will trigger the risk control rules similar to credit cards. Once the merchant types do not match in transaction time or transaction amount, or large-value transactions or integer transactions, it will trigger the risk control rules of UnionPay and temporarily freeze the account.
Triggering the risk control rules of UnionPay does not mean that there must be irregularities in the account, so users need not worry too much. When you encounter this prompt, pay attention to the safety of personal payment environment, try not to change login equipment frequently, often go offline for small consumption, and use China UnionPay Express and credit cards reasonably, and the risk control will naturally be cancelled. The ultimate goal of UnionPay is to protect personal funds.
