Now is the best time, because goods are everywhere, and now is the worst time, because fakes are flooding. IBM seems to want to help humans solve this problem, and it has developed a new technology that can identify fake drugs and fake diamonds. IBM set up a new project called "Verifier", which wants to develop a recognition system consisting of a smartphone camera, an app, blockchain technology, and AI technology. The camera can capture clear images to a micron level. App Can be downloaded anytime, anywhere. You may think that some things are smaller than red blood cells, and the smartphone lens can't be photographed because the red blood cell is only 5 microns wide. IBM said that your opinion is wrong. Verifier and spectrometer "discover" the special optical characteristics of the material, and then compare the collected information with the Crypto Anchored database to distinguish between true and false. With this new technology, consumers only need a few seconds to tell the truth. At that time, we only need to install Verifier on the phone to judge the true and false. When will Verifier technology be available to the public? do not know yet. According to speculation, such a product may appear soon, and it will become a transformative technology. The pin refers to the connection between the internal circuit of the integrated circuit (chip) and the peripheral circuit, and the pin constitutes the interface of the chip. According to the function, the pins of AT89S52 can be divided into four categories: main power supply, external crystal oscillator or oscillator, multi-function I/O port, and control, strobe and reset.
