Are there any RFID tagging systems available for home use?

Seems to me RFID microtagging technology would be very useful for home inventory, particularly for locating an item that is lost in the house somewhere, e.g., Ipod, hammer, lens cap, etc. Another use would be to identify from a PC list you maintain, just what an item is for, such as this is a battery charger for a Nikon camera. In use you would put a tag on an item and record what it is on your computer. When you need to find it, you enter the tag number and search the house with a locating device. Or, for identifying an object, you scan it and the computer locates its info.
I know these technologies exist in businesses, but are any available to the public?

They're available, but this will separate the wheat from the chaff.

All is not hopeless, check out the side links. I was pretty excited when Transit Connect offered an RFID system for the vehicle. I thought "wow, if I could tag all my tools, it would tell me if I had them all before I moved the vehicle". Then the reality set it… If it was a tool left on a jobsite, the RFID reader wouldn't tell me where it was, and I'd have to go through the long list of items to find the missing one. The problem is the long range units are expensive and the tags are bulky or expensive or both.
