At the top right on this side there you find a "Charge Zen" dropdown menu. There is a "My Wallet" link in it.
(Zen is the global perfect world currency)
Unfortunatly i have never seen a prepaid card, but it should give you X Zen, when you redeem it there. This should be mentioned on the package.
When your perfect world account is charged with some Zen, you can transfere it to STO on the "My Wallet" site. You will get 80cp for 100zen. Just remember, you can not convert any cp back to Zen! The cryptic points are bound to sto.
I did this 2 days ago: I linked my sto/pwe account, converted 350zen i had left on my pwe account to sto and got 280cp for it.

The cards were printed before sto was part of pwe ^^
