Recently, in an electronic market, a variety of blank access cards are placed on the counters of merchants copying access control cards.

The MLM in the community turned out to be a universal access control card. Upon learning of this situation, the owners of the community were surprised at first, and then joined forces to initiate a campaign to confiscate the universal access control card. What makes the community owners full of questions is how did this kind of universal card appear?

　　 One "read" and one "write" copy One access control card only needs to "press" two buttons

"Their access control card was copied." Yesterday morning, a community owner said that after inquiring from the owners, they learned that the access control card held by the MLM was realized by copying. "The access control card can easily be Copy, then, what is the significance of the access control system? How to ensure the safety of the community owners?" The owners are very worried about this.

　　 So, can the access tag be copied? Yesterday, the reporter visited a number of electronic markets for investigation.

　　 At the electronic counter on the first floor of an electronic market on Laodong Road, when she heard that the community access card was to be copied, a female boss said it was okay. After she took the keychain-shaped access card that the reporter handed over, she placed it on the surface of a handheld instrument and pressed a "read" button. String a 10-digit number, "As long as you can read the number, you can copy it."

　　 She took out a blue card from a paper bag under the counter and said it was an empty card without any information in it. Now, just copy the number in the access control card that needs to be copied into the empty card. Still, on the instrument, she was holding, she pressed a "write" button, and in about 5 seconds, she said it was done.

　　 The reporter was worried, and asked repeatedly, is that okay? So, the female boss scanned the original card and the duplicate card on the handheld instrument once, and every time a series of numbers appeared on the surface of the instrument. The numbers displayed twice are the same. The reporter collected and prepared the access control cards of multiple communities from colleagues in advance, and then asked them to copy the access control cards of another community. After the copying was completed, the woman showed a receipt for payment, "a copy of 10 yuan, the lowest price is 9 yuan." After copying two cards, she received a total of 18 yuan.

　　 Copy an access card for 5~10 yuan, the whole process does not require identity verification

When the woman went to exchange money, the reporter noticed that the instrument held by the lady at the electronic counter had the words "Handheld RFID Writer" on it, and under this row of letters, there were "power", "card reading", "card writing", etc. Three indicator lights. In the middle part of the instrument, there are two buttons "read" and "write".

What is a "Handheld RFIDWriter"? Associate Professor Xie Kai of the School of Space Science and Technology of Xidian University said this is the "handheld card writer" used to copy the access control card. "Reading" means reading out the information in the original card. To write is to copy.

At 11 o'clock in the morning, in the electronic market of Caochangpo, a female boss at a counter also said that it is possible to copy the access card. The price here will be different according to the complex program of the chip in the access card. A simple copy of the access card is 5 yuan, a complicated copy is 10 yuan, "As long as you can read the information contained in the access control card, you can copy." Here, the tool she used to copy the card is also a "hand-held card writer". ".

　　 When copying the access card, the bosses of the two electronic counters did not ask the reporter to show any residence procedures or identity information.

Can the copied card open the unit door of the community? At noon yesterday, the reporter took these three copied access cards to the first community of Biandong Street, the first community of Zhuque Street, and the first community of Chang'an West Road for trial. It was found that the security door of the community could be opened easily. When used, there is no difference between the copied access control card and the original card used by the community owner.

　　Some community property management also has omissions, and some do not need identity information to buy access control cards

　　 The reporter visited several communities in Xi’an and learned that this kind of community access control system that swipes a card to enter the community gates and unit doors is common.

　　 It is understood that after the implementation of the access control system, the community property will issue 3 access control cards to each owner free of charge. This is considering that the general owner family is a family of three. If it is lost or more is needed, it must be filed at the property and then purchased.

Can non-community owners buy access control cards? Yesterday afternoon, the reporter called the property service number of 10 communities in Xi’an. Some communities said that they need to bring their ID cards to purchase, while others need to provide a lease contract with the owners. A property in Hechengxi said that as long as the house number can be reported, the unit's access card can be purchased.

　　 And the fees for re-applying access control cards given by these community properties range from 15, 20, and 30 yuan each, which are more expensive than those copied from the market. In this situation, many community owners believe that this is an omission in community property management. If criminals copy these access control cards, the owners will suffer losses.
