How much do you know about the two-dimensional code module

Two-dimensional code is the so-called two-dimensional bar code, in today's society can be said to be everywhere, no small volume can store a lot of information, for our life and work have brought great convenience, so we will talk about two-dimensional code module today.

From a professional point of view, two-dimensional code is a coding method based on geometric pattern arrangement, which can store a large amount of data information in a small space. Different from one-dimensional bar codes, two-dimensional codes can take advantage of vertical space, making information capacity and redundancy significantly improved. This technology originated in Japan in 1994 and was named QR Code, short for "Quick Response", referring to its fast reading characteristics.

In recent years, with the development of science and technology, the application field of two-dimensional code module has become more and more extensive, especially in the mobile field. Alipay and wechat have adopted two-dimensional code technology, and users can complete transactions by simple scanning, which greatly improves the payment efficiency.

The reason why the two-dimensional code module is recognized by the public, of course, can not be just because of the convenience it brings, the most important thing is that it can provide enough security, built-in precision algorithm plus dynamic authentication, one-time password and other multiple verification mechanisms to ensure the security of two-dimensional code.

With the development of the Internet of Things, two-dimensional code technology is also constantly evolving, and now some people have proposed the idea of combining two-dimensional code with radio frequency identification technology, so that it can not only be tracked in the visual range, but also exchange information in a longer distance, broadening the scope of application of two-dimensional code module.

Now we have entered the 5G era, artificial intelligence and other technologies are becoming more and more mature, two-dimensional code module is expected to achieve more innovative applications, of course, technology has always been a double-edged sword, the popularity of two-dimensional code module can promote the development of information society, but also brought the challenge of personal privacy protection.

The QR code module can act as a bridge between the physical world and the digital world, and this small square contains a lot of power, we should make full use of its convenience, but not ignore the security and privacy challenges that come with it. Of course, we can enjoy the productive life it brings, but we must always be vigilant to ensure that our digital world is just as convenient and safe.
