ZK software's after-sales service is like a zombie, so technicians are arrogant.

In the past few weeks, due to the company's business needs, we plan to purchase a batch of machines of the consumer type, which is roughly similar to the automatic vending machine model of the school canteen.

The following functions are generally required:

1. Connect to the LAN and communicate with the server through a switch;

2. You can set the Server IP address, port, and other information. By swiping the card to communicate with the server, the server automatically deducts the card amount and returns the corresponding result;

3. There are multiple consumption modes, such as the amount mode and commodity mode;

 

After the product screening, we chose the cm10 consumer machine of central control technology for the following reasons:

1,Central Control TechnologyA group company is a large company.

2. The product does meet our requirements. I have been to the Guangzhou sales department and thought there are still many features.

3. There are factories and production bases in Dongguan, Guangdong, and relevant technical support in Shenzhen;

 

Well, with the above conditions, we plan to purchase one for secondary development, so the remittance is sent by Dongguan.

After receiving the cm10 consumer Device of central control technology, I don't know how to proceed with the secondary development event because they providedCodeIt is not applicable to idcm10 consumer. As a result, I contacted the seller multiple times and finally got their consumer ID communication co-design .doc. This document is very simple mainly to describe the HTTP request and returned information, but it can be seen that there are a lot of incorrect words and the descriptions of some instructions are inconsistent.

 

So I contacted the sales staff again, and then gave me their phone number for Shenzhen technology. After a few days, I finally got a response from someone.

What's most hateful is that making a phone call to the Shenzhen Technology Department of the Central Control Technology Department is the most depressing and complaining thing for me. There are several reasons:

 

1. A phone call is a waste of three minutes, and I often cannot find anyone;

 

2. Call the front-end to contact the consumer data department. The front-end says no.

3. Then I went to the phone and told the front-end to know where I was. I finally talked to a person for a minute and suddenly said that I was not responsible for him. The tone was really unbearable, it seems that he is a customer of mine. I 'd like to help you with it, and he said he could not transfer it;

4. Alas, tangle. The next day, I found that only one person is responsible for Secondary Development of the ID consumer machine;

5. So I called again and switched over. Yes, this time this person is more arrogant, there is no basic telephone etiquette, feed you where it is, I said that you just bought your Central Control ID cm10 a few days ago; he said, "I, ask where you are. Speechless, I said it was "Guangzhou ". Well, after several minutes of struggle, I began to ask why I couldn't communicate with ID cm10 based on the Protocol. He didn't even hear what I said, and said, "You have returned yet ", I said "yes ". He said, "You don't need to return it to the machine. It will come and take whatever it wants ". Depressed, you thought I was a fairy. How do I know what the machine wants? So I had to develop a second time to determine what commands the machine sends and what data I should return to it. He said: "Have you ever performed integrated development? You don't want to send messages to a consumer ". Depressed ~~~, I was so arrogant that I became a new employee and did not do anything. After talking about it, I can't solve it directly. Do I say other people will? He said: "No, You should evaluate the risks if you buy such a product ". I said, "you said you had secondary development support. Can you provide QQ Remote Assistance? ". "No", he said. End ~~~

 

6. After several days, I called again. "Hello, I have debugged it according to your agreement.ProgramBut only two commands can communicate with each other, "he said." Where are you? ". I said: "Guangzhou ". He said, "What customers are you buying ?"; I said, "does it matter ?", He also said, "You don't have to send any information to the machine, but it will come and get it if you want". Another sentence is the Birdman. I said, "according to the protocol instructions, all the returned results are returned. Our software records the messages that communicate with the consumer. If you don't want to send them to you, can you see the problem ?". He said, "Come to Shenzhen." I thought, "Sorry, I want to go to Shenzhen. If the problem can be solved .", I said, "One day we arrived in Guangzhou will be gone ". He said: "We can't have someone dedicated to help you solve the problem on our side." Hey, grandma, who asked you to help us solve the problem on a full-time basis. I said, "but now there is a problem. Please help me ". He said: "Well, CTRL + Shift + F11 to check the communication between the monitoring server and the consumer ". so when I pressed the button and didn't reflect it, I said there was no response. He thought for a long time and said, "Ctrl + Shift + F10. Are you sure you want to be the same first. ". End ~~~

7. After lunch, I can't tell the difference. The command for consumption is:

 

Request/iclock/pos_getrequest \ Sn = 4799321460184 & sequ = 55 & Card = 3389373 & posmoney = 300 & postype = 1
Return: ret = OK
Sequ = 55
Balance = 81312
Retnumber = 0
Username = Sam
Sendtime= 20120307142508609

 

8. So I got through the phone number of the central controller, answered the phone number, and switched again. After finding the person on the phone in the morning, I said, "I have compared the returned information, but our own program cannot be used for consumption ". He said, "Are they all the same? There is no way to do it. Does he know what's wrong with your program ?". I said, "I tracked it. It is exactly the same as the data returned by the background program you provided .". He said, "Well, I don't know. You can contact Guangzhou .". I said, "I will send you a log to check it," he said. "It's useless to send it. Come to Shenzhen. We can't help you solve this problem on a full-time basis .". I said, "let me send you our program to see if it is wrong." He thought for a long time, "okay ."

9. I changed the code and sent it to him. In fact, if I didn't solve the problem, I really wouldn't want to give it to them. There are two reasons: 1. Password-related transactions may occur; 2. They do not have related sdks or demos. Maybe they want me to give them a free demo. But to solve the problem, I simplified the program again.

10. I called them again and said, "Zheng Gong, I have sent you a program just now. Please help me to see it ". He said: "sent? ". I said, "Well, call me now. ". He said, "Well ".

The tone is not warm, and the tone of contempt is mixed, so I really want to come and kill him.

Alas ~~ I don't know when the results will be returned. Here I really want to scold you, center control technology. your after-sales service is also like a shit. It's too bad for big companies.

I also tried to leave a message on their official website asking to solve the problem, but no one has ever contacted me.
