Automated Gate Machine

There are primarily entry gate machines, exit gate machines, and bi-directional gate machines. The main function is to check the validity of the tickets held by passengers, verifying if the ticket belongs to the current transportation system, has value, is within the validity period, and contains the correct information code. If the ticket meets these conditions, the machine records the time, station number, device number, and encodes an information code on the ticket. It also prompts the passenger whether they are entering, exiting, or need to go to the ticket booth for an update. The system supports passing through the gates using single journey tickets, stored value cards, QR codes, facial recognition, and UnionPay cards.
