You can now apply RFID technology for personal use.  Tikitag allows you tag your own items which can then be linked to a computer application or web application.  You can place a RFID tag on that minature Eiffel Tower you bought in France years ago and open your web browser to your online photo album of vacation pictures.  You could send invitations to family and friends with a tag that would open the same online photo album.  This is very new and is still in beta.

You can check it out at www.tikitag.com.
