The bullet train didn't brush the ticket when it entered the station. Can you brush the gate when you leave the station?

Of course you can go out. The gate at the exit only depends on whether the ticket and the number of trains are consistent, regardless of whether the ticket is checked when entering the station; Some passengers take the manual passage when entering the station instead of the automatic ticket checking machine, and they can also take the automatic ticket brushing machine when leaving the station.

The gate is a channel blocking device (channel management equipment), which is used to manage the flow of people and regulate the entry and exit of pedestrians. Mainly used in subway gate system and toll station system. Its most basic and core function is that it can only pass through one person at a time, and it can be used in the entrance passage of various charging and access control occasions.

Extended data

Since the development of gates, the identification methods used are: swiping cards (including magnetic cards, ID cards, ic cards, various cards, etc. ), document scanning (ID card, passport, military officer's card, etc. ), barcode/QR code, biometrics (fingerprint, iris, face) and so on.

1, card, certificate and bar code/two-dimensional code are identification methods, which are characterized by only identifying cards, certificates and codes and not knowing others. Advantages: fast identification speed and high success rate, so the traffic speed is fast.

Disadvantages: If pedestrians forget to bring or lose their cards/certificates/codes, they will have no access rights. Moreover, this way does not know others themselves, and it is impossible to ensure that the card/certificate/code is consistent with others. In addition, the card/certificate/code may be stolen, which brings great security risks to management.

2. The biometric features of fingerprints and irises are based on identifying the biometric features of people passing by, so the reliability is relatively high. Advantages: Compared with card/certificate/code identification, it saves the trouble of carrying external media of these machines.

Disadvantages: it is easy to collect fingerprints and iris, and it is easier to disguise, and there are certain loopholes in use. Moreover, the passage needs the active cooperation of pedestrians to verify.

3. Face recognition method uses visible light to obtain face image information. In the process of pedestrian movement, the camera can actively capture the facial information of pedestrians and quickly identify the traffic rights of pedestrians. Advantages: I can verify it when I am present. There is no coercion, no active cooperation, no contact, and it is difficult to disguise my face.

The identification methods used by gates in different places are different, some use a certain identification method alone, and some use it in combination. For example, subway gates are generally used for credit card identification, and customs gates are used for face, certificate and fingerprint identification.
