During the long period of May 1st or 11th, most people choose to travel abroad. It is a very good choice to relax their mood and adjust their work and living conditions. Someone may report to a travel agency to go together, maybe two or three in a group, but no matter which way, staying in a hotel is indispensable. Most hotels now use self-check-in machines instead of manual check-in procedures for travelers. Picture: The use of the self-check-in machine has greatly improved the hotel's service quality and work efficiency. It has many advantages: First, it can be on duty 24 hours a day, there is no human factor in it, and there is no need for hotel staff to assist in operations, and only the passengers themselves can complete the procedures. In addition, it is easy to operate and convenient to query. It has a touch screen, so its human-computer interaction is very good, and guests can use it to open a room, check out, check out and leave the store. At the same time, improving passenger efficiency and saving time also makes outstanding contributions to the reduction of hotel operating costs and the improvement of service quality. The self-service check-in machine is very reassuring in terms of maintainability. It is durable and stable, which is the best definition of it.
