Recently, a transplant patient who was in a concert and could not be reached by the hospital (the family’s mobile phones were switched off) was eventually located as his mother’s phone had a GPS device embedded in it. Emergency services tracked them down and got them to the operating table within a short time. Time is of essence in transplant cases and organs that match a particular patient are rare to come by. GPS saved the day in this case and life of the patient literally. This potentially life saving feature will in the near future be part of all mobiles phones. A recent law will soon require all mobile phones to have this device, so you can be tracked anywhere and located in case of an emergency.
