Perhaps you have encountered a similar situation
Going to work, squeezing the time to get to the office, but found that the queue of the place where the card is punched is very long, it may be late when it is time to swipe
In fact, this trouble can be solved
If there is a 2.4G chip in the card, through the battery control, you can actively search for the card reader within 200 meters and complete the card swipe, so that you do not need to put the card on the card reader to swipe the card.
Chairman of Aif
Zhao Huafeng
39 years old, with a professional background in communications engineering, has participated in the development of the source program of intelligent network switches; at the end of last year, he and his team independently developed the first 2.4G chip (short-range digital transmission and reception integrated circuit). Some schools in Guangdong put into use
At the end of last year, the chairman of Chengdu-based Aif, Zhao Huafeng, led the team to manufacture a 2.4G chip (short-range digital transmission and reception integrated circuit). Through battery control, it can actively search for card readers within 200 meters and complete Swipe the card, so you don't need to put the card on the card reader to swipe the card. Recently, Zhao Huafeng, who was in Shenzhen, introduced the 2.4G chip to the reporter by telephone.
"Do not make ordinary chips,
To be the core technology of the Internet of Things "
In 2005, Zhao Huafeng began doing RFID testing, which is radio frequency identification. In his work, he learned many RFID technologies, such as cards using 900 trillion chips and 13.56 trillion chips, such as access control cards and bank cards, etc., must be close to the reader to respond, the card is in a passive position, and use 2.4G chips Card, you can actively "contact" the card reader to complete the card reading.
In 2008, Zhao Huafeng established a studio in Shenzhen. His purpose is very clear, "Do not make ordinary chips, do the core technology of the Internet of Things." The "core technology" here refers to the 2.4G chip, which can be in 200 Within a distance of meters, digital signals are transmitted through the power supply instead of analog signals, which means that the chip can record information and become an information collector.
The first 2.4G chip developed by the team
Reveal the veil at the end of last year
After nearly 3 years of research and development, the first 2.4G chip made by Zhao Huafeng and his team was unveiled at the end of last year. This chip is a well-designed framework in China, and then sent to foreign tapes to make an 8-inch wafer disk, and then each wafer disk is cut into more than 7000 4 mm square chips, each chip is also No big fingernails.
In order to develop 2.4G chips, Zhao Huafeng invested tens of millions, and so far there has been no big gains. He said that not only the design and processing technology will affect the chip, but the chip aging test and practical application are also crucial to determine the success or failure. Therefore, the product must be tested for 1 to 2 years before it can be judged. This uncertainty has caused Zhao Huafeng to face many doubts when looking for investment. "This thing already exists in foreign countries. You haven't seen that you can do better, and the income is so slow. Is it okay?" Zhao Huafeng understands their ideas. Tens of millions of investment in other industries may have earned more. And most of those who do technology like him have dreams, "I always think that if you don't do technology with independent property rights, you will never be able to catch up with others, so I must do technology with independent property rights." This paranoia made Zhao Huafeng stick to the present.
"Chengdu is like Silicon Valley in the United States and has an environment suitable for research and development"
At present, 2.4G chips have been put into use in some schools in Guangdong. Enter the student and parent information in the chip and put it into the student card. When students enter and leave the school, not only do they not have to swipe the card, parents can also receive SMS notifications to understand the students' movements.
Zhao Huafeng ’s dream is more than that. He believes that the positioning and judgment characteristics of 2.4G chips can realize more ideas that are subject to technology. For example, cold chain control, during the transportation of vaccines, if the temperature drops and rises, then the vaccine will be scrapped, and it is difficult to record the temperature at all times during transportation. Using the feature of 2.4G chip data collection, the temperature can be formed Graph to determine whether the vaccine has failed.
In order to achieve better development, in June last year, Zhao Huafeng set up the company ’s headquarters in Chengdu. In his view, Chengdu ’s university resources, living environment and costs are very suitable for the development of the company. An environment suitable for research and development. "
