Motorola's password in a pill and electronic tattoo

Always forgetting your password? Tech company Motorola is working on some rather unusual solutions!

They've unveiled an electronic 'tattoo' that sticks to your skin. It has a circuit so gadgets can identify you.

Another experimental idea is a password pill you swallow - that transmits a signal to devices outside the body.

The pill doesn't need batteries because it's powered by stomach acid - but Motorola bosses say it won't be on sale any time soon.

So you'll have to keep remembering those passwords for now!
