The self-service check-in machine has gradually become the first choice of major hotels. Its fast check-in and fast check-out are popular. It not only improves the efficiency of customers' work, but also saves hotel operating costs. It not only perfectly demonstrates the good service quality, but also improves The quality of the hotel is indispensable in today's fast-paced society! My work is mainly on projects, and I will go to the project location after I have a project. On average, I travel once a week, spend the weekend at home, and then continue to go to the project location non-stop. Each project can range from several months to several years. Therefore, it takes quite a long period of time to travel to and from multiple cities frequently every year, and I often encounter flight delays, so every time I get off the plane, I feel exhausted and I want to find a hotel to stay as soon as possible. There are several good choices, mainly because the hotel has a self-service check-in machine, which is very convenient! You can complete the room opening, check-out, and checkout through self-service equipment, which is fast, convenient and easy! I won a lot of time and achieved a lot of achievements!
