Since the central bank launched the "259 document", the offline POS machines of all payment institutions have fully implemented the "one machine, one code".
What is "one machine, one code"?
"One machine, one code" means that each machine can only have one merchant after the transaction, unlike before, which can automatically match merchants.
This undoubtedly has a great impact on friends who need to use credit ka turnover every month. Because of the long-term credit card transaction on a merchant, it is easy for the bank to think that there are violations in the transaction, which will lead to the bank to carry out risk control, derating and other ways to deal with the card used.
Why do we need to implement "one machine, one code"?
The main thing is to improve the security and convenience of payment. It also prevents some users from using POS to "run points and launder money" for criminals
How to deal with "one machine, one code"?
First, you can prepare a few more POS machines and take turns to brush, but such costs have undoubtedly increased a lot, and each machine also deducts other expenses, such as traffic fees and deposits. And it's impossible to carry so many machines with you every day, it's really inconvenient, so it's not recommended to use this method here.
Second, you can consider using diversified transactions, that is, online POS, which is much more convenient than offline POS machines, and because of the characteristics of online transactions, it will not be affected by "one machine and one code". All you need is a mobile phone and an app to solve the problem.
There is also a point to note here that UnionPay has regulations that each merchant can only register 15 small and micro merchants, and more than 15 cannot continue to register, so cardholders must pay more attention when choosing products.
