In this era of rapid development of science and technology, the importance of ID card, as a necessary document for "one person in hand", is self-evident.
In a simple card, all the information of the holder is recorded.
It can even be said that in life, as big as buying a house and a car, as small as staying in a hotel and traveling, it is inseparable from this "special certificate". In addition to the ID card, a copy is required as an "auxiliary" and ultimately as an archival document in addition to the ID card.
For this reason, people who often do business have multiple copies stored at home in case they need them.
At this time, in order to avoid the leakage of their own information, or the use of people with impure motives, they will often put a coin next to the photocopied document to "encrypt".
Good guys, how does a small coin have such a big "ability"? What is the principle of this "special encryption"?
1. "Small body, big energy"
As an indispensable existence in people's daily life, ID card not only carries personal identity information, but also an indispensable identity certificate in our social activities.
It is precisely for this reason that protecting one's personal information from being exposed has become the "basic operation" of every adult.
In some cases, we need to provide a copy of our ID card to complete certain tasks. But some unscrupulous merchants may secretly keep copies of their customers and use them for improper purposes.
This not only violates the privacy of the individual, but also may cause unnecessary trouble to the individual.
The easiest and most effective way to solve this problem is to place a coin next to it when making a copy of the ID card.
After all, every aspect of a coin is strictly fixed, and when it is photocopied, its unique three-dimensional form is fully recorded.
It also means that if someone tries to make another copy of this copy with the coin marking, they will not be able to get a normal and clear copy.
This method is equivalent to adding a proprietary security mark to the copy of the ID card, making a second copy almost impossible.
In addition to the use of coins, there are other measures that can be taken to protect personal information.
Even if the document is accidentally lost, you must go to explain the reason as soon as possible to prevent the bad guys from using the lost ID card to carry out illegal activities.
It can be said that protecting the security of personal information is not only the need to protect one's own rights and interests, but also the responsibility that everyone should bear.
Through the coin method we mentioned, you can effectively prevent the risk of misuse of your documents and ensure that information security is not violated.
But in addition to coins adding security, there are many ways to talk about identity in everyday life. Of course, in these methods, there is even a misunderstanding that everyone has been "believing to be the truth but then the rumor".
II. Statement
ID card, as an important document in each of our lives, has always been the focus of public attention.
Especially in modern society, mobile phones have become a must-have item for almost everyone, so there is a saying: mobile phones will have a demagnetizing effect on ID cards.
So, is there any scientific basis for this claim?
To solve this problem, we must first understand the basic knowledge and working principle of ID cards. It is mainly made of plastic and contains RF chips and coils.
When you bring your ID card close to the surface of the reader, they will read and write the data through the transmission of radio waves.
This is the radio frequency identification technology used in the second generation of ID cards, which is what we often call contactless IC card technology.
So how did the saying "ID card be demagnetized by mobile phone" come about?
In fact, this statement is mainly based on the perception of magnetic stripe cards ten years ago.
At that time, bank cards, credit cards, etc. were magnetic stripe cards, and when these cards were in contact with the mobile phone for a long time, it was indeed possible to demagnetize.
However, with the development of technology, magnetic stripe technology is no longer used in the second-generation ID cards used today.
Therefore, from a scientific point of view, mobile phones will not cause the ID card to become invalid.
In this case, why are so many people still worried about the demagnetization effect of mobile phones on ID cards? This may be because the public does not know enough about ID cards, or there are some problems in the process of information dissemination.
As we said, the frequency and intensity of the electromagnetic waves of the mobile phone are not enough to cause any damage to the ID card. Unless the ID card is exposed to extreme conditions such as strong magnetic fields or high temperatures, its information is safe.
In addition to the misperception that degaussing leads to the wrong perception of waste cards, there are some other common misconceptions and cognitive biases.
It's like someone thinks that once there is a problem with the film on the ID card, it needs to be replaced in time. But in fact, this film is an anti-counterfeiting technology, which can make the ID card more anti-counterfeiting and wear-resistant, and it is completely unnecessary for you to reissue it twice.
Of course, if the film has flashed, blistered, etc., it really needs to be replaced in time.
Of course, if you insist on saying that the phenomenon of mobile phone demagnetization also exists, but this situation is relatively rare. Even if there were, it is actually possible that something else caused the damage to the document and not the phone.
But do you know that in addition to modern people, our "ancestors" also have ID cards, and their identity cards are not only in various forms, but also "high and low".
2. The wisdom of the ancients
In fact, the concept of ID card is not a modern product, it has undergone thousands of years of evolution, and has even witnessed the changes and development of mainland society.
The "earliest" ID card appeared during the Shang Dynasty reform in the Qin Dynasty, and in order to better manage the personnel, the "photo post" came into being under the needs of the society.
Its main material is a bamboo identification mark, which is engraved with personal portraits and identity information, similar to the function of modern identity cards.
Those who do not have it will be recognized as black households in the official uniform and will be punished.
However, due to its ease of falsification, the system has gradually lost its effectiveness.
In the Sui and Tang dynasties, the "fish talisman" replaced the "photo post" and became the officially recognized form of ID card. It is engraved not only with personal official information, but also with information about the family.
However, compared to the ID card that everyone can have now, this special certificate was only available to princes and nobles in ancient times.
Until the Ming Dynasty, on the basis of the predecessors, the "waist card" evolved into a "domino". The production process is more complex, and the relevant information is more complete.
What's more, ordinary people during this period could also use this object to prove their identity.
The Qing dynasty abandoned the traditional identity card system in favor of clothing patterns and gemstones on official hats to distinguish status levels. This transformation reflects the reform and innovation of the traditional system by the Qing rulers.
After the founding of the People's Republic of China, with the establishment and improvement of the household registration system, ID cards have gradually become an important part of people's daily life.
The initial work card and attestation letter gradually transitioned to the first generation of ID cards, and each person had their own ID number, which greatly improved the efficiency and accuracy of identity verification.
The author thinks
I have to admit that with the development of society and the progress of science and technology, people's daily life is becoming more and more convenient and fast.
But the disadvantage that comes with it is the gradual increase in the risk of personal information leakage. It is precisely for this reason that while enjoying convenience, everyone also needs to continuously improve their awareness of risk prevention.
In particular, it is necessary to exercise caution when handling relevant documents such as ID cards. After all, some people may give a copy of their ID card to another person or institution because of a moment of negligence.
But they don't know how many serious consequences are hidden because of their unconscious actions.
To this end, we also need to know how to properly copy, keep and destroy important documents such as copies of ID cards to avoid unnecessary troubles and losses.
Do you have any tips to prevent information leakage?
