Ahhh. Ummm. If your phome is there, wouldn't you be too? Unless of course you were trying tp be ob so cool and ddag your fingers on the ground. JK of course. A very good point. Can't take your prints when you are in surgery.
Don't know anything about iPhones, so I stand to be corrected. The idea is to set the ICE number as the lock screen background. That way the phone doesn't have to be accessed, just the screen activated.
