"Juan likes to manage his hotel in the most optimal and profitable way possible. Therefore, he knows that he needs new technologies to be competitive. The question is, which solution to use that is quick to implement as he doesn't have enough spare time? Something flexible, he has several employees that greet the guests at any time and place in the hotel; It needs to be simple to use, he does not want to bother his employees with training or complex systems; Something that is affordable and does not require investing in other computer systems, he already has a collection of other bulky obsolete systems."
