Hey all. I have a question. If I buy something expensive like 300-400$ the bank will call to card holder to confirm the transaction or not ? And how i can check who site have a VBV security ? Sorry for my bad english

The bank wont call the cardholder for 400 bucks, atleast the chances of that are very low. The shop could call the number provided upon the purchase tho so make sure you provide a number that u have access to. In terms of VBV the shop usually has an image that reflects the vbv security, once you will have more experience you will understand what im talking about

Can I use VoIP numbers for purchase ? And what they will ask ?

it all depends on websites. websites that receive thousands of orders on daily basis wont have time to be calling numbers, rather they use other means like shipping only to billing address

big shops doesn't call or do anything
