Access control card is easier than key to crack a card

Today, many buildings in the provincial capital have adopted access control cards to open the security door system. Simply take a round card and you can easily open the security door. Many residents think that such a card looks more technologically than an ordinary key and is provided for by the property. It should be able to better ensure the security of the community.

However, the actual situation is not the case. Recently, the public, Ms. Zhang, told this newspaper that many stalls on the street can copy such access control cards. Even more convenient than key matching, in fact, the access control card does not provide access control. . There are also public concerns that the access control card is so easy to copy. Is it also very easy to copy public transport IC cards and telephone cards? If so, it would be too unsafe.

In the past few days, the reporter conducted a visit investigation.

Reporter’s shot: Less than a minute to copy an access control card In order to verify Ms. Zhang’s statement, on December 9th and 10th, the reporter consulted with a number of key exchange booths such as Jiefang Road, Shuangta Street and Sports Road. Except for some mobile key distribution booths that do not have this business, most of the booths that have long been engaged in key service can do the copying of access control cards.

At a booth on Jiefang Road, when the reporter asked if the copy of the access control card could be copied, the owner readily said that 20 yuan would be copied. Afterwards, the shopkeeper took out a plastic bag from under the counter and pulled out a square blue machine. The top part of the machine had a “prox card duplicator” with a small screen in the middle and two small buttons on the bottom. "Read" and "Copy". Another plastic bag is filled with red and blue access cards. These are blank access cards. The owner plugged in the machine, put the access control card provided by the reporter on the sensing area, pressed the “read” button, and then took out a blank access card on top, pressed the “copy” button, and the green light came on. a bit. He then handed the card over to the reporter and said that it was "completely prepared." The whole process took less than one minute.

According to the owner, he started the business from 2004. “This is a special industry that must hold special industry operating licenses.” The owner of a stall issued a public security department’s permit, saying that at the time, it would be very difficult to handle this document. However, many colleagues now buy copy machines from the Internet. , quietly doing the same business.

Market research: The access control card copying machine can easily buy reporters to search the Internet for “access control card copying machines” and found similar websites with as many as hundreds of homes ranging from RMB 300 to RMB 800. One of the businessmen’s business is hot, and the 350-item access control card copy machine sold 12 units in one week.

On the morning of December 10th, the reporter visited several decoration cities in the provincial capital. Many businesses selling unit security doors were equipped with such access control card copy machines. The price ranged from 200 yuan to 500 yuan.

Is there any relevant department to supervise the sale of this kind of copy machine? A boss told reporters that he had been selling for several years and rarely asked. Most of the purchases are property companies or street key holders. The boss made a calculation. A machine is calculated at 300 yuan. A blank access control card is 2 yuan. A copy of the access control card on the street is between 20 yuan and 30 yuan, and the cost can be recovered in one month.

It is understood that the access control card for general residential households is uniformly issued by the Residential Property Management Office, and each household is granted about three free grants. For additional applications, a fee of between ten to tens of yuan is required. Some residential communities also have strict restrictions on the number of access control cards for each household. If you want to add additional cards, you must apply for a real estate license or a home purchase contract. However, many property officials stated that they did not know that the access card was so easy to duplicate.

"I thought the access control card was safer than the key. It seems we and the owners can't trust the access control card too much." A property person said that they would pay more attention to safety issues.

Electronic Engineer: ID card copying is very simple IC card is difficult to copy in the key distribution booth, whether it is a round access control card or similar bank card rectangular access card can be copied. In this regard, many citizens are concerned that the access control card that was thought to be safe is so easy to duplicate. That is to say, public transport IC cards and telephone cards belong to IC cards, and they are also very easy to copy. "If it is also easy to copy, it is too insecure," said one citizen.

In this regard, the reporter consulted the owner of the key distribution booth. According to them, the access control card belongs to the ID card, and the ID card is well copied. The technical content of the IC card is relatively high and the security level is high and it is difficult to copy.

So, what's the difference between an IC card and an ID card? The reporter contacted Mr. Song, an electronic engineer. He said that ID cards are all called identity cards. They are fixed-number proximity cards and are widely used in various access control systems. There is no restriction on the reading of the card number in the ID card. The card number is generally 10 bits and it is easy to copy.

Compared with ID cards, IC cards are more secure. For example, IC cards are used in bus cards and parking lot cards. There are also card numbers, user data, permission to use, and amount of money on cards. Data is read and written. Each entry requires a corresponding password authentication, which is a two-way authentication card that is relatively difficult to copy.
