Pedestrian gates have become very common in our lives. Whether in schools, shopping malls or subway ticket gates we can see its figure. We see the pedestrian access gates because of the different functions of different places, so the use of access control identification method is also different. Our most common channel gate access control identification method is infrared photoelectric sensor detection, through the sensor probe to achieve pedestrian detection. But in addition to the speed pass gate access control identification method there are many, such as ID card recognition, face recognition and so on. Next with me to look at the speed gate and what access control identification way it.

The current general pedestrian gate access control identification methods include infrared detection, IC/ID card, ID card recognition, two-dimensional code recognition, NFC identification, face recognition, etc.

1. Infrared detection: pedestrian gates in the entrance and exit installation of infrared detection probe. Generally speaking, the entrance and exit are installed two pairs each, and some projects need to install a total of six pairs. Rely on the working principle of photoelectric sensors for pedestrian detection. Because the speed gate is not a general swing gate, but an advanced gate with high detection accuracy and fast passage speed. Usually, in order to adapt to the characteristics of the speed gate, the choice of photoelectric sensor in the selection of photoelectric sensor is generally selected to the photoelectric sensor, sometimes also installed in the exit of the speed gate diffuse reflection photoelectric sensor. The pair of infrared detector high accuracy, fast response time, effective handling of large crowd access, keep open. However, the security of personal identification is zero, and it is only suitable for crowd evacuation in public places. But because the photoelectric sensor in the speed pass door is an indispensable component, so the infrared photoelectric sensor detection is also often used in combination with other security performance higher access identification system.

2. IC/ID card: IC/ID card identification method compared with infrared detection to a certain extent identifies the person entering and leaving. The card must be encrypted and sent, and the card reader is installed at the entrance of the pedestrian gate for reading. This card encryption is relatively low-level and easy to crack. Moreover, cannot identify the person who uses the card, it is easy to appear that others use the card.

3. ID card identification: ID card identification is different from the ordinary card identification. ID card not only varies from person to person, and it is difficult to crack the replica, can display the ID card information with the display system, also can identify the entrants and exits more securely.

4. QR code recognition: QR code scanning of pedestrian gate, through the cell phone display or paper printed QR code, according to the predetermined rules to confirm, through the passage, the cell phone QR code, a faster. Paper QR code is generally used as a one-time visitor system is more convenient.

5. NFC identification: Based on NFC technology, it can communicate with the fast-growing composite NFC standard devices (such as smartphones, tablets, etc.). Through proximity communication, it prevents the security problems of possible interception and decryption by far-field communication technologies (e.g. wifi, Bluetooth, etc.), and is suitable for places where strict privacy is required, with small size and low power consumption.

6. Face recognition: through database comparison, real-time collection of 286 face features point comparison, accuracy of 99.5%, can be quickly identified as 0.05 s. Face recognition can effectively prevent other decryption, theft, disguise, etc., only the highest security level of identification, fingerprint and ID card identification, multiple identification methods to jointly authenticate identity information, face information and fingerprint and ID card information unified The access control can only be opened by the highest security level, fingerprint and ID card identification, multiple authentication of identity information, unification of face information with fingerprint and ID card information. Applicable to the need for highly confidential locations and identity information for a period of strict screening.
