Traveling is a good choice for people during holidays. It is not only an opportunity for relaxation, but also a good adjustment to work and life. When resting, most people choose hotels to check in. The self-service check-in machine is a machine used to replace manual check-in procedures for passengers, through which passengers can check in quickly. Picture: Self-check-in machine, can I be on duty 24 hours a day? The answer is obvious, no. It can only be solved by shifting work. Although this solves the problem, it also increases the cost invisibly. In addition, the manual check-in procedure takes a long time, especially for those who come late. Passengers want to rest early, but they can't get it, and they complain to the staff. In fact, all of this can be solved by using the self-service check-in machine, which can be used normally for 24 hours, simplify the procedures, and integrate the check-out, check-in and check-out functions into one to give full play to its effect. The self-service check-in machine simplifies the cumbersome check-in procedures. Of course, it is much faster than manual check-in. It saves the rest time for passengers, and the passengers will certainly have a good mood.
