I've not used them, just thought it was an interesting concept some enterprising online entrepreneur has started to make a buck! Actually, someone else suggested using a keychain flash drive to put this info on plus any hotel/air/car etc confos. As long as you has access to your laptop or a computer with a USB port, this would work. They mentioned that they would not be comfortable having this info out on the net. Another person mentioned, "Online and secure don't seem to go together..."

I threw it out to see what other FTers thought...
