A virtual bitcoin debit card is a regular prepaid debit Visa card for online payments. You will receive the card information virtually via email and can use it immediately.
Some differences between Wirex virtual card and plastic card:
A virtual card has no physical form (no piece of plastic you can actually hold), which means you can only use it for online payments. 您将通过电子邮件获得您的卡的资料（卡号、 有效期和 CVV代码）。
You can start using your virtual card(s) as soon as you received it in your email. There is no need to wait for delivery, unlike with plastic.
