I want your future phone to require each user to fill up their basic emergency data sheet like Name,Age,Birthday,BloodType,Allergies,Contact person incase of emergency, Etc. (Speed Dial)By the use of owner thumb it can easily view their record incase of emergency. Police and doctors can easily identify them if they are unconscious. Smartphone must serve like a national ID for easy access. This kind of information is a great help especially travelling alone.
