IF YOU GET LEFT BEHIND DO NOT GET ANYTHING MARKED< IMPLANTED<STAMPED OR ANYTHING IN YOUR BODY!
Motorola has announced it is looking at alternatives to traditional passwords in a bid to make logging into online sites, or accessing mobile phones, more secure.
Among the ideas discussed at the D11 conference in California on Wednesday were electronic tattoos and authentication pills that people swallow.
The tattoos, developed by Massachusetts-based engineering firm MC10, contain flexible electronic circuits that are attached to the wearer's skin using a rubber stamp.
HOW DOES THE MC10 ELECTRONIC TATTOO WORK?
A researcher at the University of Illinois used standard CMOS semiconductor computer chip technologies to create the Biostamp.
It uses high-performance silicon and can stretch up to 200 per cent.
The Biostamp can monitor temperature, hydration and strain, among other medical statistics
The first prototypes were stuck on using an plaster-style patches.
More recent prototypes are applied directly to the skin using a rubber stamp.
It can then be covered with spray-on bandage to make it more durable and waterproof enough to wash.
The MC10 Biostamp is said to last up to two weeks before it starts to come loose.
MC10 originally designed the tattoos, called Biostamps, to help medical teams measure the health of their patients either remotely, or without the need for large expensive machinery.
Motorola claims that the circuits, which also contain antennae and built-in sensors, could be adapted to work with mobile phones and tablets.
The mobile devices could then be used to confirm the owner's identity and log them in to accounts automatically.
This would prevent thieves and other people from being able to access a phone, or individual apps on the device, if it is stolen or lost.
Another idea presented during the keynote talk at the Wall Street Journal conference with head of Motorola Dennis Woodside and senior vice president for advanced technology and products, Regina Dugan, was a swallowable pill.
The Proteus Digital Health pill has already been approved by the U.S. Food and Drug Adminstration and was given European regulatory approval in 2010.
