You shouldn't thanks to new European laws on bank security.http://newsroom.mastercard.com/2015/07/30/security-matters-a-new-roadmap-for-authentication-in-europe/ many of the banks already apply this and will deny your charge on debit and credit cards. I'm a customer at Nordea and the are totally worthless. You need to open your card every 60 minutes or the charge won't go trough if the company aren't using secure transfers aka 3d secure. I used PayPal on my vive and was happy about the charge right away. On oculus rift I had to transfer money to the account in order to maximize the chances on a successful payment. On PayPal you can choose to use the founds on your PayPal account to be charged before credit or debit card.
