Your card’s card verification value (CVV) code (a.k.a. “security code”) adds extra security when you’re making purchases without handing over your physical card. It’s a 3-digit code found on the back of your physical card.
You can view your CVV code (and other card details) within the Cogni App, simply by tapping the card image. You can of course hide the info by tapping again on the card image.
