iButtons are chips enclosed in a stainless steel case, manufactured exclusively by Dallas Semiconductors. Each chip has a unique serial number, which means that no two iButtons are alike. Besides that, they require no power, no cables or any other sort of installation. iButtons have proved to be the best solution for directing the patrol officer in his tours and controlling the rounds, given that iButtons are resistant, durable, and cannot be reproduced.
The user shall use the iButtons in programming Guardus to identify and control the checkpoints of the rounds to be performed, and also other relevant checkpoints such as supervisors, employees and so on.
