Hi... lots of times I am in public places such as the library and other places that offer Wifi and I have always wondered what type of information (if any) is available to the main computer supplying the Wifi....

For instance.... are things like my credit card information, name, email addys visibile to the central computer? Or does each PC that is connected have some sort of "unique identifier" of some sorts that if in the wrong hands could put you at some kind of risk?

Just curious and wondering.

Thanks in advance

If there is a "main computer supplying the Wifi" all the information on the wireless network is available to that computer.

Even if there is no "main computer" but just a router or access point, it's possible that any information can be logged or captured. For that matter, anything you do anywhere that goes onto any network or the internet could be tracked, logged, captured, etc. Someone would have to doing something malicious and have access to the network to so, or if it's an corporate environment it could be policy to monitor traffic. All of this can also apply to a wired connection as well. Data going to and from secure sites such as those that use SSL should be secure and the data wouldn't just appear on another computer but nothing is 100% secure.
