The search for effective solutions that automate processes is constantly growing and, as a result, large companies are continually investing in technologies for this purpose. In an environment where a large part of the processes are critical, such as a hospital, agility and security are indispensable characteristics for these processes to take place effectively. The control of medicines, equipment and patients are examples of critical applications in this environment.
