The virtual card becomes active immediately upon creation via Conferma Pay Control. The card will be deactivated based on the option you select from the Duration dropdown; 3 days, 1, 2 or 4 weeks.
You should consider if you’re creating a virtual card to be active for only 3 days, will the mobile user access the card and make a purchase within that time frame? You may want to consider allowing 1 week of card activation.
