A virtual card is a digital card that only exists within your xPortal App, and does not come linked to a physical card. It has a 16-digit card number, a CVV and an expiration date that can be created instantly through a website or mobile app. You can use a virtual card for online shopping, over the phone purchases, or any transaction that requires entering a card number. A virtual card can offer you more security and control over your payments, as you can freeze it after each purchase.
