Anonymous users2024-02-07The card reader is used to read the smart card information (card number) of the card swiping person, and then converts it into an electrical signal and sends it to the access control controller, and the controller judges whether the cardholder has been authorized to enter the door during this time period according to the card number received, and completes the work of unlocking, keeping the lock and so on according to the result of the judgment.
For networked access control systems, the controller also accepts personnel information and corresponding authorization information from the management computer, and at the same time transmits card records of the entry and exit doors to the computer.

Anonymous users2024-02-05Access card. Encrypt your phone with NFC.
Comes with the rotten brother poor door card simulation software.
1.Open the NFC Reader Tool on the standby machine, the NFC Reader Tool needs to log in with WeChat, if WeChat is not installed on the standby machine, the software will call WeChat to scan the code to log in. After logging in, click Connect Device, and after the device is successfully connected, bring the card close to the card reader.
Then use the one-click decryption function of the software, and wait patiently for the software to decrypt it, which is generally finished in a few minutes to dozens of minutes. After the decryption is completed, you will get the dump file, then use the software's save key function to save the key, which will be useful later.
NFC Reader Tool format the female card to get the non-encrypted mother card Many tutorials in this step tell us to prepare a non-encrypted special backdoor card that can modify the card number, and then modify the card number of the backdoor card to the card number of the parent card, and then use NFC mobile phone to simulate this non-encrypted special backdoor card with the modified card number.
NFC mobile phone simulates the non-encrypted mother card, at this time, like the first step to detect whether the access control card is encrypted, use the simulation software that comes with the system in the NFC mobile phone to simulate the non-encrypted mother card obtained in the second step, at this time, the mobile phone will not prompt the card encryption, but directly simulate successfully and enter the next step, at this time, you can operate the simulation according to the prompts.
NFC Reader Tool writes a dump file to your phone. First of all, we set the simulated non-encrypted mother card on the mobile phone as the default card (generally the default card selection interface will appear when swiping the card, and the correct card can only be called when the mobile phone swipes the card after setting the default card). Then, put your phone on the card reader, turn on the write function of the NFC Reader Tool, select the key hungry and dump files obtained above, and start writing.
In the same way, you can change the non-encrypted female card in the 0x02 back to the encrypted female card. __
Once the write is successful, you're done!!

Anonymous users2024-02-04The so-called IC card, he automatically writes the data in the card, and everyone's information is different, which is encryption. The ID card is to read the ID number of this card to complete the card reading process, so there are copies everywhere outside, and the IC card can only be issued through software.

Anonymous users2024-02-02Let's talk about the same principle of IC card and fingerprint unlocking:
If the identity information is the same as that stored in the system (previously registered), the identity is correct, and the corresponding action is performed, such as opening the door lock.
Differences: 1. IC card. Generally, it is a contactless RF radio frequency card, which uses the card issuer to write a unique identification code (ID) to the card in advance before use, and at the same time puts this ID code into the system's database (i.e., registration) to facilitate identity comparison. Swiping the IC card is the process of reading the ID code, comparing the read ID code with the ID code stored by the system, and carrying out subsequent actions (such as displaying identity information, unlocking, etc.) after identity judgment.
2. Fingerprint sensor. First of all, the fingerprint is registered with the system through the fingerprint sensor (registered fingerprint information), which is also stored in the system's database. Pressing the fingerprint is the process of reading the fingerprint information, comparing the read fingerprint information with the fingerprint information stored by the system, and performing subsequent actions (such as displaying identity information, unlocking, etc.) after identity judgment.
First of all, there are several pain points in the traditional building access control system, one is the high construction cost, because each household has an extension, coupled with the use of limited links, the cost of equipment and auxiliary materials and the project are very high; Second, because these intermediate devices are numerous and complex, they are easy to cause signal interference, resulting in a very high failure rate, and most systems are paralyzed or semi-paralyzed after 3-5 years; Third, the later maintenance is complex, because the line is buried through a weak current well, the later troubleshooting cost is high and complex, and the amount of work is huge. >>>More
The elevator internal selection button (floor button) generally has four wires, two power lines, two signal lines, the card reader is just a switch, one of the signal lines of the button is disconnected, and the control signal line of the card reader is strung into the disconnected signal line. When someone swipes the card, it is equivalent to the button signal line is connected to realize the floor selection, and when no one swipes the card, the button signal line is disconnected and the floor cannot be selected.
The collection scope of the TOOM public opinion monitoring system includes but is not limited to newspapers and periodicals, forums, blogs, Weibo, WeChat public and other information, and automatically filters invalid data, and the collection frequency needs to reach the minute level at the earliest, which can achieve 24/7 uninterrupted automatic collection. The number of daily collection and updates reaches millions, and the system supports cloud computing storage and retrieval of big data. >>>More
Laser hair removal is based on the principle of selective photothermodynamics, by reasonably adjusting the laser wavelength energy pulse width, the laser can pass through the surface layer to reach the root hair follicle of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, so that the hair loses its ability to regenerate, and at the same time does not damage the surrounding tissues, and the pain is mild, laser hair removal is currently the safest, fastest and long-lasting hair removal technology.
