Ok here is the poop: Never do any sort of banking wirelessly. If you do I can read it. You are using a radio frequency to connect to the router that ANYONE in the area can pick up. Even if it is encrypted, if I record your key strokes I can figure out what you are sending. 128 bit encryption is not infallible. There are also a ton of other thing a hacker can do. The easiest to do especially if you have a password set up for your wireless connection would be to spoof your router. This is how they do it. They find out why kind of router you have, very easy to do, send out a spoofed log in window that looks exactly like your normal log in. You type in your user name and password, it says "You password is wrong please try again" and then they swap back to your real router. You just gave them your user name and password and they can see EVERYTHING you broadcast from that point on. People do this a lot in coffee shops because its so easy to do.

So in the future DON’T bank over your wireless and you will be safe.
