This explains the difference's between WPA - WEP - WPS
Four types of WPS have been defined. At the simplest level, a PIN, or personal identification number, is placed on a placard or sticker on the router and works as a pre-shared key. In some designs, the key needs to be entered using the router setup. In others and more commonly, it’s preconfigured in the router memory. All home networking Wi-Fi devices made after January, 2007 support this method. Interestingly, the Windows 7 beta asks the user to obtain the PIN number from the sticker on the modem by default, although it also provides a handy link to the dialog for password (security key) entry.
