Digital Tattoos and Pills Could Replace Passwords in the Future

Sick of remembering all of your passwords? Your frustration may be solved. Motorola's vision for mobile isn't just its new smartphone - the Google company also has wearable, tattoo-embedded, and swallowable gadgets in the works.

Recently, Advanced Technology and Projects Group Chief Regina Dugan attended D11 with an electronic tattoo that could be worn on human skin for one week at a time, and used to cut through the numerous authentication processes we go through every day. Slashgearreported that the tattoos use a stretchable electronics system that can work even as it flexes on a moving arm. (Crazy, right?) There has been some criticism of wearable tech like that young people won't wear them, but she believes it is far more likely they would wear a digital tattoo.
