Does the access card affect the car keys?

Access card is a common object in life and a communication card to enter the building. Who would have thought that such an inconspicuous object would affect the start of the car?

The access card itself has no influence on the car, but it has built-in IC chip, induction coil, antenna and other components, so it will not be abnormal at ordinary times, but as long as it enters the electromagnetic wave radiation range, it will immediately generate induced current, activate the antenna of the access card and emit radio frequency signals, and the card reader will make corresponding actions after recognizing the signals.

That's how access cards are used. It's more convenient for us to use them. Almost all car keys have an anti-theft system, and there is also a reading coil in this system, which is equivalent to a small card reader. When starting the car, the coil needs to release energy. This energy not only activates the ignition key, but also activates the access card.

According to the above, when the access card is activated, it will release a signal, and sometimes this signal will be recognized by the car anti-theft system, forming radiation coupling. The interference of the signal will make the key make a wrong judgment, thus making the car unable to start, and even damaging some functions of the key in serious cases.

Therefore, in life, we still have to pay attention to these details. After all, science and technology are developing rapidly, and there are many things we don't know. If we suddenly turn off the engine while driving and miss, it will be a catastrophe.

Can an American classic car China drive?

I believe many people in China are fans of classic cars. However, due to the annual emission of domestic cars, classic cars can't drive on the road. However, these old cars are very common in America. I don't know if you have any questions about this. Why can American classic cars go on the road, but not China? Don't American classic cars need annual inspection?

Although compulsory scrapping has been abolished in China, the frequency of vehicle inspection will increase every year with the increase of vehicle age. /kloc-cars over 0/5 are audited twice a year, and cars over 20 years old are audited four times a year, so it is difficult to drive a car for a long time in China. But in America, old cars are a symbol of the times. In the eyes of many Americans, owning an old car is very proud. In the eyes of China people, too many people look down on old cars and even call them broken cars. If they have been driving for two or three years, they will be eager to change.

In America, there is no annual inspection in many places. No matter how old the car is, the owner can choose to drive it on the road as long as it can drive. After all, cars are private property. As long as it is private property, it can be protected by the US Constitution. For Americans, cars are their own private property and how to use them is up to them. However, some States in the United States still need annual inspection, but even the annual inspection is very loose. Some States can have an annual inspection every two years, and some States, such as Alaska, only have an annual inspection once in a lifetime. There are also states with strict vehicle inspection, such as Massachusetts, New Hampshire, New York and Vermont.

There is a big difference between American and domestic vehicle inspection, which does not mean that the American system is necessarily good, nor does it mean that the domestic system is necessarily poor, and the national conditions of the two countries are still different. For example, in the United States, if a car has an accident on the road, the punishment for the perpetrator is quite severe, which makes Americans consciously check the car. No one dares to drive on the road easily in this faulty car. If there is an accident, they will be convicted of murder and may be imprisoned for life. The domestic inspection is strict, and it is relatively "free" after going on the road, and the accident punishment will be lighter.

Although many States in the United States do not require annual inspection, there are still requirements for automobile exhaust emissions. If it is found to be unqualified, the relevant departments will inform the owner to carry out rectification until it reaches the standard before continuing to drive on the road. Therefore, these classic cars can continue to exist because the owners keep renovating their cars to restore power and performance.

In addition, the United States is sparsely populated and has insufficient police force. Generally speaking, as long as you don't drive in those busy cities, there aren't so many policemen checking cars. Moreover, so many people in the United States live in suburban rural areas, and the average distance between these places and cities is about 40 kilometers. If you drive in these places, the police will check you. What kind of fate is that, so the illegal car is essentially not caught.

Although classic cars can be renovated and modified continuously, their performance is still much worse than that of modern cars. After all, the production time is different and the technology is relatively backward. The reason why our country will implement a strict annual inspection system for cars is because there are many people and cars in our country. If we don't manage them, all kinds of substandard cars will be on the road, which is a huge hidden danger to road safety.

To sum up, this is why the United States can use classic cars decades ago, but China can't. Does the access card affect the car keys? Can the American classic car China drive @20 19?
