A US Virtual Visa Card is a 16-digit visa card number that is provided immediately upon redemption.
These Virtual cards are intended for use online in the US only, and are generally accepted wherever Visa Debit is accepted.
Note: You have 4 months to redeem your visa card, and 7 months to use the cards after that. Once you can view your card it is active and ready to use online like a regular credit card.
US Virtual Visa cards are also not compatible with PayPal or any similar service intended to transfer funds from one account to another.
