Photo by chuttersnap on Unsplash One of solution we studied here at Allinit srl has been a Presence Control system for a public Hospital. There where various problems there, about employees, but we want remark two solved with our solution. One was related to the safety of healthcare operators. Not rarely the relatives of a victim in an accident had an excessive and sometimes violent reaction to a lousy notice given by a healthcare operator, so a fast way to ask for help from security staff could be useful. The other was that sometimes many employees leave the site, at the same time, without notice or coordination, going the others in difficulty. As you probably guess, the most challenging problem to solve, wasn't the tech solution, but persuade the employees that the answer will not affect their privacy negatively. But this is another story and another post.
