Thanks to Mark Van Duinen for this one!

Samsung have developed a small (1/4 inch square) RFID reader chip; looks like they'll be trying to embed these in phones, etc.

This could allow consumer devices - especially mobile ones - to pick up data from RFID chips on products, signage, transit, etc.

From InfoWorld's notice on the same subject:

Some RFID tags on food or medicine products might give information on ingredients or dosages, while RFID tags at bus stops can offer schedules or tell when the next bus will arrive.

According to Cellular News,

the global demand for mobile RFID is expected to grow from $26.9 billion in 2007 to $701 billion by 2010, for a compound annual growth of 196 percent.

Here's hoping they don't repeat the mistakes of the CueCat - sending data about what you're scanning back to the mothership. The furor over that, especially among early adopters, pretty much sank the product.
