There are chips and coils in the interlayer of the second-generation ID card. When the ID card reader emits electromagnetic wave card reading signal, the coil of the second-generation ID card induces electromagnetic wave to generate current, and the chip starts to work under the action of current, and the information of the second-generation ID card is transmitted back to the reader through electromagnetic wave, so that the reader can know the information on the second-generation ID card.
Why can I steal the second-generation ID card information through my wallet?
The second-generation ID card has the same function as the bus card. The bus card doesn't need to be taken out of the bag, so the card reader can know how much money is in your card and deduct your fare. Similarly, criminals can use the ID card reader to read the information of your ID card and know your name, address, date of birth and other information, and then use this information to know your home phone number, work unit and family members.
1, the second generation card adopts radio frequency technology, and its working frequency is 13.56MHz. In our living environment, the frequencies of mobile phones, microwave ovens, communication towers, audio and video, televisions, computers, electrostatic copiers, etc. are constantly changing from 800 MHz to 1200 MHz, and long-term strong electromagnetic changes can easily cause the second generation card to be internal. According to the regulations of the state, it costs 40 yuan to reissue the second generation certificate.
2. The biggest difference between the second-generation certificate and the first-generation certificate is that the machine reading function is added on the original basis, and the verification machine is produced by ten designated units of the state, but some people produce it privately for economic benefits regardless of the state ban. They are sold in the market, and it is very easy for criminals to steal our personal information after buying them. Once personal information is stolen, it will bring a lot of trouble, and personal interests and spirit may be greatly hurt.
3. For adults, the validity of the ID card ranges from 10 to 20 years or even life. Also protect the surface of the second generation certificate to prevent wear and tear.
4. The second-generation ID card is a legal and valid personal document, and a copy is often needed. At present, most of them are electrostatic copiers, so for the safety of photocopied ID cards.
How "Lidanka Protection Guard" protects the second-generation card and the information in the card;
"Lidan Guardian" is a national patent product. The patent application number is 200720053934.7, which is a special casing made of high-tech nano-composite materials produced by the latest international technology through special processing technology. The special material of the sleeve can reduce the external electromagnetic wave attenuation by 100000 times or even 1000000 times, and it cannot penetrate the ID card. If the coil can't induce electromagnetic waves, it won't produce current. In the past, this product was mainly used in some foreign spy departments to equip special cover to protect their own safety and prevent themselves from being stolen. Now it has been developed and used by our company to make a protective card set, the main purpose of which is to protect our citizenship information from being maliciously read and stolen by others.
Simple method for detecting Lidan protective device;
Put the bus card in the fence of Li Dan and read the card reader on the bus. The card reader did not respond, which proved the protective effect of this set.
