How to replace community access control with mobile phone NFC?

Hello, first of all, it depends on what brand and system the mobile phone is. Android and Apple have different methods, encrypted and unencrypted access cards are also different, and the operations of various brand manufacturers are slightly different. Let me introduce the methods to you, and the basic methods are the same. The operation is similar, the steps are not complicated, and the needs of Xiaobai users can be met without tossing.

I. unencrypted access card

1, Xiaomi mobile phone

First, open Xiaomi wallet and select the "access card" below (in some system versions, it is displayed as "access card simulation". If your mobile phone supports NFC but does not display it, please update the system first ~)-Click "Start Detection"-Stick the access card in the box on the back (common unencrypted cards can be simulated. If the software prompts that the card is encrypted, it cannot be simulated. Authentication is required after reading. )-The simulation can be started after completion.

2. Huawei mobile phone

The operation is basically the same as that of Xiaomi. Click Huawei Applications-Wallet-Card Package-Click the+Select button in the upper right corner-Click the simulated physical access card and stick the access card on the back box (common unencrypted cards can be simulated. If the software prompt card is encrypted, it can't be simulated. After reading it, you can start the simulation. Huawei mobile phone and NFC automatic identification scene are really useful. You don't need to select a card, just double-click the power button (you can turn on NFC at any time and stick it on the access control to pop it up automatically). This is really much better than Xiaomi's NFC!

Can simulate ordinary white cards and water-drop blue cards.

Second, the encryption access card

1, the encrypted access card has some technical contents to operate. It is suggested that friends with certain hands-on ability can try it. If you have a Huawei mobile phone, you can also try its own copy card number function, which is relatively simple. The first step is the same as copying the unencrypted card above, but you should pay attention. When the card reading fails, the "Copy Card Number" button will appear. Click Copy Card Number to copy the encrypted card number. If the copy is successful, you can try to open the door (whether you can open the door depends on the verification mechanism of the access control manufacturer, and you can open the door only by verifying the card number).

2. This needs to be realized by tools, and a 2 yuan C is needed.

Uid card (bought by a treasure), mct software (mifare classic tool), 2.06 Chinese version I used, and an nfc mobile phone (a mobile phone). First, open the mct on the mobile phone and read the encrypted access card, provided that the encrypted access card has a sector password in the mct dictionary. At present, the general community has not changed much, and it is generally successful. After mct reads successfully, click Write Dump (. Then take the cuid card to brush it. After successful cloning, click the format card, and then swipe the cuid card, and the cuid will be formatted, so that you can get an unencrypted access card. Then, mobile phone B opens the wallet and reads this card. It must be analog, but the current analog card only has 0 sectors of data, and there is no encrypted data. Then, mobile phone A opens the software, reads the encryption card in the cell and writes it into the dump. Open the access card just copied by mobile phone B, and get mobile phone A when swiping the card. The position is right. Just hear the sound from mobile phone A and detect it, you can brush the encrypted data to mobile phone B, and mobile phone B simulates the encrypted access card. Of course, it is useless to check the access control of manufacturer information, because the access control card part of mobile phone simulation is fixed and cannot be modified!

Third, Apple mobile phone

In order to swipe the access card, Apple needs curve realization. First, we need to add a type of bus card to Apple's mobile phone. Please find the "Wallet" app on the phone screen and open it. Please click the+button in the upper right corner of your wallet. Then click the Scan or Add Card button to continue. Next we can buy a transportation card. After being successfully added to Apple's mobile phone, you need to find an access card administrator, usually the property in your community. Then, let him input the NFC information of your Apple phone into the access control system. After joining, the access control system can recognize the NFC signal on Apple's mobile phone and open the door. Of course, you can also add the bus card to your watch and then you can brush your watch when you go out.

Huawei mobile phone can realize the function of community access control key.

On Huawei mobile phones that support NFC, you can use the "wallet" application that comes with Huawei mobile phones to turn them into access cards, and you don't need to bring ugly access cards when you go out. You can search Huawei official website to see if your mobile phone supports NFC. Only mobile phones that support NFC function can brush access control.

Let me talk about my own settings first. My mobile phone is Glory 9, which supports NFC function. First, open the wallet app. On Huawei mobile phones, this app should be pre-installed and available on every Huawei mobile phone.

Click the card package, then click the "+"sign in the upper right corner and select "Key". The interface is as follows:

Then click the copy physical door key, and then stick your keychain on the back of the phone. Follow the prompts, and the final setting is successful. The access control key just set will be available in the card package interface. The interface is as follows:

When using, click on the credit card on the home page, select the key just set, and put the mobile phone near the entrance guard.

The NFC function of the mobile phone is still very convenient. In addition to replacing access cards, it can also replace bus cards and bank cards. Now I basically don't have to bring my access card and bus card when I go out. I use the bus and subway to brush my mobile phone.

At present, the s8 follow-up models of Samsung pay have already supported the access card function, and the binding is very convenient. You just need to brush your mobile phone when you go home, and you can easily enter the door.

If you use a Xiaomi mobile phone with NFC function (Xiaomi 5/6/8 or Note series and some Redmi models), you can use the "key card simulation" in Xiaomi wallet, which is a solution without Root. Although you need to upload your ID card for authentication before binding, the steps are not complicated and you can meet the needs of Xiaobai users without tossing.

First, open Xiaomi wallet and select "key card" below (some system versions display "key card simulation". If your mobile phone supports NFC but does not display it, please update the system first ~)

Click "start detection"

Stick the access card on the trunk.

Common unencrypted cards can be simulated. If the software prompts that the card is encrypted, it cannot be simulated.

When finished, you can start the simulation.

Can simulate ordinary white cards and water-drop blue cards;

Solution of non-Xiaomi NFC mobile phone

If you don't use Xiaomi mobile phone, and your mobile phone also has NFC function, you can save the country with the help of third-party tools after obtaining Root permission.

Download this "NFC Card Emulation" after getting Root permission (some app stores don't have it, but you can download it from other app stores such as pea pods).

Sticking the card on the back will automatically get the card information.

After obtaining the card information, the software will pop up a window to prompt to set the card name. After setting the name, you can start the simulation.

If the mobile phone without Root permission will fail in this step, it needs to obtain Root permission to simulate. As for how to get Root permission, it is beyond the scope of this article, so I won't go into details.

In the comment area, another way is to take the mobile phone to the property, and let the property authorize the mobile phone (a certain fee may be charged), so that the mobile phone can be used as an access card to brush the access control.

I have to say that the NFC technology of mobile phones is still quite powerful. When it first appeared, everyone thought it didn't work, but with the intelligence of mobile terminal equipment, it can be used as a tiny and irreplaceable intelligent scene of life, such as bus cards and access cards, making it popular.

If you want to use mobile phone NFC instead of community access control, you must first confirm whether the mobile phone has NFC function. Find the corresponding NFC application in the small mobile phone. There will be the word simulation on the application. Aim the access card at the mobile phone, and the card reading function can be realized. Simple and rude, you will learn it as soon as you learn it.

Of course, this simulation function can not only simulate the access card of the community, but also simulate the access card of the building where the company is located, thus completely realizing the great task of having a mobile phone to travel around the world.

Of course, if you want to realize the simulation function, you need to authenticate the real name of the mobile phone, which can ensure the security of the access card and the safety of your family. Otherwise, once the mobile phone is lost, it will be stolen, which is not conducive to personal safety and property safety.

The above simple methods are limited to Xiaomi and Huawei mobile phones. If you are not these two brands, you are a mobile phone outside these two brands. This function can be achieved through root permissions and with the help of third-party software.

Technology can only facilitate our life, but it can't replace all aspects of our life. Therefore, I personally suggest that you bring a physical community access card when you go out, because sometimes you forget to charge your mobile phone. At this time, the money is in the mobile phone and the card is also in the mobile phone. Then we can only do nothing.

How to replace community access control with mobile phone NFC? For this problem, most mobile phone manufacturers have given perfect solutions. OPPO wallet of OPPO mobile phone, Xiaomi wallet of Xiaomi mobile phone, Huawei wallet and Huawei honor wallet can all realize this function. Next, let's take Huawei's mobile phone as an example to introduce how to use NFC instead of community access control. The overall operation and functions of other mobile phones are similar. You can refer to them.

1. Open Huawei wallet software, enter the door key, and click Add to select the door key type you want to add.

2. If you need to simulate the existing access card, just click the first simulation. At this time, just follow the prompts and put the access card on the back of the phone. Huawei currently supports 13.56MHz unencrypted door keys.

3. Of course, some communities and locks support direct access, and some hotels can also use these directly as room cards.

Click the simulation button according to the interface prompt to enter the waiting access card interface. At this point, you can read the access card near the NFC sensing area of the mobile phone. This process is actually copying the data of the access card sector block. After the data reading is completed, the simulated NFC access card is completed. The names and patterns saved later can be completed according to the interface prompts. It shows that NFC chip card belongs to approach induction card. The whole chip is divided into 16 sector bits, and each sector is divided into 4 blocks, totaling 64 blocks. Each sector bit has a different custom password, which is empty by default. The simulation that comes with the mobile phone is to read the physical ID number of 1 sector, which is not encrypted. If your access card is in another sector, you may need to know the sector password and use other NFC instead of access control software for simulation operation.

Are you envious to see that many people can freely enter and exit at the university gate or at the bus and subway station with a touch of their mobile phones? Someone may have thought of it. What's in this? Why not just dig out the chip of the card? Of course, this is a way, but it's too hard to test your hands-on ability, or you can replace your mobile phone card with a SIM card that supports the subway type, and the same effect can be achieved, but if you want to queue up in the business hall or something, forget it. In fact, today we have an easier way to achieve the same effect simply by modifying the NFC values on several mobile phones. 1. Read the ID of the card first. Install a software called "NFC TagInfo". Open the NFC settings of the mobile phone, stick the campus card freight bus card on the NFC part of the back cover of the mobile phone, and read the campus card ID with "NFC TagInfo". You can see that my card ID is 13: 67: A9: 0A.

2. Modify the ID of the mobile phone NFC. Open r.e. manager, root directory->; Etc, find "libnfc-nxp.conf" in the etc folder (be careful to back up the original file! ! ! ), edit it in the text, drag it to the end of the file, and find the part similar to the picture. You can see that the default value is 0 1, 02, 03, 04, and the ID of one plus mobile phone is the same. I guess it may be the value of one plus one generation. Other mobile phones should be similar. Change this value to card ID:13,67, A9,0A. Save the changes, restart the phone, and try to pass the access control. (Note that nfc is only effective when waking up the screen, and locking the screen is not allowed. )
