Scary that Chase has that much on me already. I just bought a couple DVDs and was presented with another alternative for payment. Called Bill Me Later. An instant credit agreement between me and Chase. Odd though, All I had to do was enter my Date of Birth and last 4 of my SSN. I normally don't do stuff like that but I really wanted to see what would happen. I was approved and the DVD's are on there way. I did give a shipping address but it's not my home address.
You have an 11b wireless LAN? Probably just used your 2.4 GHz RFID to get the rest of the information they needed.
