In daily life, shopping, adding friends, opening websites, etc. Are closely related to the QR code. According to the statistics of relevant departments, the number of QR codes used every day is about 654.38+0 billion.
The question follows, won't so many QR codes be used up? What shall we do if we run out?
To answer this question, we need to know the QR code first. As early as 1994, Yuan Changhong, a Japanese scientist, added a dimension to the improved bar code, thus making a two-dimensional code.
After adding a dimension, the QR code can store a lot of information. For the two-dimensional code, the number of combinations is related to the pixels per inch of the two-dimensional code itself.
In short, the higher the pixels of a two-dimensional code, the more two-dimensional codes can be combined. So far, V40 is the largest format of two-dimensional code, 177X 177 pixels.
How many QR codes can so many pixels form? It is about 10000 to the power of 10. However, this is only a QR code in V40 format, if you count other QR code combinations.
I believe this figure far exceeds the current figure.
At present, the earth consumes 65.438+0 billion QR codes every day, and needs to consume 3.65 trillion each year. It has been 654.38+038 billion years since the birth of the universe.
Even from the beginning of the universe, humans began to consume QR codes. According to the above speed, humans only used 5x10 22.
According to this calculation, the 33X33 version of the QR code is enough for humans to use 7.3x10 260 "138 billion years", which shows that the number of QR codes generated is very huge.
In other words, if humans exist in the universe long enough, the QR code will eventually run out. However, due to its huge number, QR codes may still be used up when humans become extinct.
As far as the current development is concerned, science and technology are developing rapidly, and new things are updated quickly. Perhaps, after more than 20 years, the popular QR code will be eliminated.
Therefore, for us, there is no need to worry that the QR code will run out one day. Mainly based on two reasons: 1, the number of QR codes is huge and there is enough volume.
2. The development of science and technology is too fast, and the alternation period of things is short.
Therefore, through the above two reasons, the QR code will not be used up by everyone.
In recent years, science and technology have developed rapidly, and human beings have created many new things. In the face of new things, we may not have time to experience them, but they have passed.
As far as QR code is concerned, it is just a way in everyone's life, but it has a great influence on human beings in daily life.
