Tech company Motorola is working on an odd technology to help people, who forget their passwords.
The American multinational has unveiled an electronic " tattoo " which sticks to a person's skin and has a circuit so that gadgets can identify the person, the BBC reported.
Another idea is a password pill that can be swallowed and transmit a signal to devices that are outside the body.
Batteries are not needed for the pills, as they are powered by stomach acid,
However, the bosses of the company have said that they won't be on sale any time soon.
