Li Zhongxin and a group of livestock from 302 were having fun eating at the Lufulou Hotel. After all, they didn’t get together during the holidays and they missed some of them.

It was just that drinking made him feel a little annoying, and he didn't wait any longer! Three of the eight people in the dormitory drank too much, which made Li Zhongxin take more than ten minutes to get a taxi for them.

After Li Zhongxin returned to his residence in Harbin City, he began to prepare various supplies for tomorrow's school start.

When I was in college, I had to prepare the most things in my freshman year. When I was in my junior year, there was basically nothing to prepare, and I could basically go to school to attend classes.

The next morning, Li Zhongxin got up early, after exercising a lot, he said goodbye to Feng Banshan and started his junior year.

Li Zhongxin is the best thing. As long as he enters the campus, he basically ignores Zhongxin Company and other aspects of things, focusing on studying and happy campus life.

Attending the opening ceremony, watching the military training of freshmen, eating snacks around Hakka City, and playing computer games appropriately. Li Zhongxin's life was leisurely and leisurely, making him feel relaxed and at ease.

On the Zhongxin Company, Wang Bo and the Central Committee arrived in Russia. It is said that they would stay there for a month to two months. They had several things to do. As an important entourage, Wang Bo basically couldn't come back for a while.

Recently, Hong Bin has also set out to go abroad to work hard to make some arrangements. He basically has no time to pay attention to Li Zhongxin, and Li Zhongxin felt relaxed.

Life is always fast, but Li Zhongxin doesn’t think so! A month passed, and on National Day, Li Zhongxin went home directly.

"Brother Xiaoxin, I heard that you are back home. There is something like this here. I want to invite you to come here. Do you have this time?" Li Zhongxin just arrived home and had not waited to sit down! He received a call from Ran Hongtu.

"Grandpa Ran, do you have anything to explain on the phone? I just took the bus home, otherwise we will talk about it tomorrow?" Li Zhongxin said to Ran Hongtu with a little head over.

If it were someone else, Li Zhongxin would not have been able to hang up his phone directly, but the opposite was Ran Hongtu, the manager of Zhongxin's scientific research base. On the one hand, the old man is old, and on the other hand, Li Zhongxin has always given enough respect to scientific researchers.

"What I want to report to you is not a big deal, but it is something you have been paying attention to. It is considered that our development has been successful, so I want to invite you to come and have a look." Ran Hongtu said seriously to Li Zhongxin on the phone.

However! In this matter, Ran Hongtu did not say what was successfully developed, but said that it was something that Li Zhongxin has always paid close attention to. This was a pit that Ran Hongtu dug for Li Zhongxin.

Ran Hongtu knew clearly that if he said it thoroughly or didn't say anything, it would be very feasible for Li Zhongxin to go to Zhongxin's scientific research base.

The research and development of something I have always paid attention to has been successful?!!!

Li Zhongxin was immediately confused with a question mark?!! What is it?

"Grandpa Ran, then I'll go over to your side now. The old rules are that you ask the security guard in the building to leave me a separate elevator, and I'll take the elevator directly to your office.

Li Zhongxin took the bus from Feng Banshan and walked all the way, but he didn't understand what Ran Hongtu was talking about.

You basically don’t need to consider auto parts and other things, and you don’t need to consider the subsequent technology of VCD and DVD. Is it new materials?!

Li Zhongxin was very itchy. He felt that Ran Hongtu had a grudge and wanted to know this matter quickly.

"Zhongxin! You are here! I have such good news here. We have learned the technical equipment of the OneR code you mentioned." Ran Hongtu said to Li Zhongxin with a smile.

"What? I have understood the technical equipment of the OneR code and can be mass-produced?" Li Zhongxin immediately became happy.

Li Zhongxin is very concerned about the one-dimensional code technology and QR code technology, because Li Zhongxin knows that in the future, one-dimensional code and QR code will enter people's lives, and more and more people need to use such a technology.

One-R code is a barcode. It appeared in the 1920s and was born in the laboratory of Westinghouse Electric Company in the United States. It is a world-renowned inventor - John Comand.

He thought about automatic sub-checking of postal documents, so he invented the earliest barcode: one "bar" means the number 1, two means the number 2, and so on. At the same time, he invented a barcode reading device.

The amount of information contained in the Comand code is too low, and it is difficult to write more than 10 different codes. Later generations have implemented improvements to the barcode based on it.

In 1949, the first record of all-round barcode symbols invented by Norm Woodland and Bernard Silvo appeared in the patent literature. This first generation of barcodes adopts a ring-shaped design, just like a target for archery.

The birth of this technology has almost changed the form of business activities around the world, making cashiers more efficient and customers can save more time.

However, the first generation of barcodes still used a ring-shaped design. To complete the scanning, it is necessary to install a giant scanner with 500 watt luminous body.

After the 1960s, Japan became a defeated country in World War II in 1945, but in terms of economy, Japan entered a rapid rise.

The sales of major supermarkets in Japan naturally grew rapidly, but because cashiers needed to manually enter the commodity prices for a long time and frequently at that time, the cashiers were slow at that time, and their hands were prone to fatigue and even diseases.

Therefore, Japanese supermarket systems basically have such a scanning device that scans the code to do various things.
