What if the hotel suddenly loses power and the guest wants to check out?

Star hotels will have their own power supply, and even if there is a sudden power failure, the front desk computer will have electricity. Moreover, because most guests will pay the deposit in advance when they check in, you can check the deposit receipt. You only need to install an emergency power supply in the store, which can not only stabilize the voltage and save energy, but also supply power in time when there is a power failure, and also connect with the fire department, which is safe and convenient.
