"Virtual" refers to the fact that your debit number can only be used for online purchases (however, we are currently working on adding Apple Wallet functionality in the coming weeks). Clicking on "Show Card Numbers" will provide you with all the information you need to make an online purchase:
16 digit debit card number
Expiry date
CVV number
Please note that your card PIN is for your physical debit card, not your virtual debit card.
