Many Cards in One

MultiAccount Credit Card

Dynamics Inc has created a new computerized credit card that can re-program its own magnetic stripes and hide its account numbers. Users would press buttons on its face to switch between stored account numbers which are unlocked by entering the correct PIN. 

The card also has a lithium-polymer battery and is fully waterproof. Now you can reduce that fat-wallet effect.

Is that a Cell Tower in your Pocket?

What's in your wallet?

Do you need a better cell signal? The researchers of the major telecoms think that they have the answer - a femtocell base station.

With all the current mobile bandwidth quickly being eaten-up by all the fancy multimedia mobile apps that Google, Apple, and others put out, new solutions are being devised to relieve the growing network congestion. 

About the size of a TV remote, a femtocell operates essentially as a portable cell phone tower, but at a much lower power output. It is designed to be used in homes and offices to provide an enhanced mobile signal within a 10-meter radius.

At $150-$250, this may be the answer to your bandwidth problems.
