Can the Innovation be Put into Practice?

Hotel Technology Next Generation is a global trade association that fosters partnership among hoteliers and technology providers. On March 3rd, it awarded the first ever Most Innovative Hospitality Award to MTech for the REX Room Expeditor product.
REX is an app which integrates iPhone or iPod Touch with Property Management System (PMS) to inform room attendants “what is the next most important room for them to clean”. With this tool, the process of assigning room cleaning can be streamline, getting guests into their rooms faster.

With so many benefits of this innovation, such as turning rooms faster, improving guest experience by reducing wait time, saving time, paper, and money etc., can REX be put into practice? As far as I know, many hotels don’t allow room attendants to carry phones with them when they are at work. One of the reasons for that is to reduce external interference. However, with iPhone or iPod Touch’s personalized entertainment function, people can easily install apps, games, songs and so on into these smart devices. If every room attendant has an iPhone or iPod Touch that with their favorites games or songs, I believe it could be a big distraction for their work. But when there is a problem, there is always a solution. I will say the solution is to develop an app which can prevent installing or downloading other sources to the iPhone or iPod Touch or design a device that only for using REX.
