...I'll never lose my car keysIn the near future, all of the things we buy will contain an RFID tag (Radio Frequency Identification). These are tiny little devices that transmit a radio signal capable of traveling a short distance. Like a barcode, an RFID tag identifies a product. Stores will use them at checkout lines instead of scanning a UPC symbol. Unlike barcodes, it doesn't just identify the type of object (30GB iPod Video $299). It identifies the exact object (30GB iPod Video serial number 92384776 $299). This should also make them useful for inventory and anti-theft purposes. It also could have some negative impact on personal privacy but that's another topic of conversation.
So, once this technology hits the shelves, why can't I have my own personal RFID scanner that I can use to locate things around my house? When I buy something that I might accidentally lose, I scan it with my little RFID scanner and it adds it to an internal database. When I need to locate that something, I tell my scanner what I need to locate and walk around the house until it beeps or otherwise signals that I'm close.
