According to Xiaobian, many payment companies have recently blocked a number of merchants, and many merchants who have purchased such machines are complaining!

According to the latest information, some payment companies have thoroughly investigated one machine and multiple merchants nationwide, and one legal person retains at most one merchant. All the rest were shut down and one was found, a fine of 500. The chaos in the POS industry has reached an unprecedented level, and market violations are deteriorating. Especially last year, there were serious liquidation scams in Erqing POS and even Sanqing POS, and some merchants eventually suffered losses and nowhere to go. There are major hidden dangers in a multi-merchant POS. The main reason is that most of these machines are privately rebuilt. It is difficult to determine whether a trojan or a listening program is buried. Most people who use this pos machine are used to raise cards. Be careful, once they are The stolen brush can only secretly cry...

CCTV has exposed the existence of violations such as gold control, and there have been multiple information on multiple platforms in one screen. It is reported that many payment companies have begun to impose large-scale restrictions. At present, many payment companies have stopped the function of multiple ID cards entering the network. This will lead to the direct extinction of multi-operator multi-platforms!

Is it really the gospel of card players? Today we will unveil its mystery.

Let's talk about the multi-merchant mode of the hand brush (ie mobile phone POS):

Their core lies in the mobile phone APP, the audio card reader or the Bluetooth link card reader is nothing more than a card carrier, all data is transmitted in real time via the mobile APP and the server, then "big merchants, multi-merchants or even one machine multi-rate "It was born out of this. Everyone needs to know that our POS machines, whether they are banks or third parties, have only two data transmission modes: one is direct connection mode and the other is inter-connect mode.

At present, most of the POS machines on the market use the inter-connect mode (except UnionPay business), so that their data can be converted in the background of their own servers. The code-hopping code is also the mode and crazy, our merchants, The region and even the rate are converted in the background of the server. After the above steps are completed, they will report the adjusted result transmission to UnionPay, then the so-called multi-merchant is formed by hand brush. . Now let's talk about the so-called one-machine multi-merchant of traditional POS machines. Everyone needs to know that before the POS machine enters the network, the agent must import the SN code of the POS machine on hand into the system, and then report the order. After the approval, the merchant number and SN will be verified. The code does the binding match. Our merchants generally get the POS machine that fills the program. After the standby device is approved, the person who sells your machine will tell you the boot download program. With such a step, everyone's POS machine can be used normally.

So, can such an important SN code be modified at will?

The answer is yes! According to the principle, if you apply for 3 merchant numbers, A is a supermarket, B is a gas station, C is a home appliance, but there is only one machine, then the agent must falsify in the SN code of the import system, and the imported SN code must be If you edit your own, then your A, B, C and other merchant numbers will be bound to these SN codes, and all you have to do is modify the SN code of the machine (similar to the phone number). Match), this technology is difficult for ordinary merchants, very difficult to achieve, we only talk about ideas, not much talk about practices. Maybe a lot of people will think, since it is so difficult, why the seller above a treasure said it is very simple.

The following is the second mode of production, you can pick up the POS machine on hand, take the New World ME31 as an example, after the administrator logs in, you will see an anti-activation, right, this is the anti-activation, all operations It is done here. Then the problem has come out again. Always switch like this. Does the payment company know? They are definitely known, because the SN code of the machine and the merchant number are bound in the background of the payment company. After you have 3-5 times of anti-activation, maybe your machine will be locked, how to solve it? Looking for an agent to report to the company. Can it be unlimited? Estimated is difficult, because the agent does not have so much time to help you deal with this, and the multi-merchant gameplay itself is illegal operation. Speaking so much, everyone must be cautious and cautious when dealing with a multi-operator!
