I suppose you can do all of the depositing actions, transfers in the system including transfer to your card, pay by that card. However you cannot withdraw funds to other payment systems, other visa/mastercards/payment systems. If in doubt contact support. Just saying i was perfectly fine paying without verification
Ok, guess I just have to try with a little amount to see how it goes and see if it asks for verification or not if I try to buy stuff with it on-line like digital goods etc.
