It seems that the input information for the automatic check-in machine is checked at the counter in the back, and if you don't know how to use it or there is a mistake in filling it out, the mistake will be pointed out loudly (What is the automatic machine for? If there is, wouldn't it be a good idea to configure the system to force you to re-enter that part?) When I checked out, I was having trouble getting my room card key unless I pressed the button labeled "Check Out" on the automated machine, but after a while, the counter said in a loud voice and gestured "Check Out". Instructions to press a button. The customer service was a bit unfriendly and I didn't feel very good about it. Some hotels allow you to check out by simply posting the key in a box, but if you are using your own system, I think you need to think of a more kind way to help customers understand.
