The "rCard" is the size of a credit card, and the thickness of two coins, but can be used to display video, photos, databases, presentations, run demo software and play games.

They're being billed as the "first interactive marketing device", designed to offer businesses with the ultimate electronic brochure.

A company called CEO IQ is distributing the rCard, and announced today that they're now available.

Unlike USB thumb drives, or mini-CDs, the rCard has its own video display and controls allowing consumers to use them without a PC.

Information is loaded on to an rCard by means of a tiny USB port located on its side, or via infrared.

The rCard can store up to 1 gigabyte of information, and can last up to four hours of continuous use, or approximately 200 viewings. When not in use, it has a shelf life of seven years.

So will we be seeing rCards stuffed inside of cereal boxes and magazines? Probably not anytime soon. Each card currently costs about $25.00 to produce with a minimum buy of 250,000 units. But it's probable that in our lifetime, we'll find ourselves browsing magazines at the newstands, and having these buggers fall out on to the ground.

CEO IQ has a very good video demo.
