Your Digital Lili card contains the exact same information as your physical debit card: same card number, expiration date and CVV Security Code. When you shop online, these are the 3 card details merchants will ask you to process your payment (sometimes they’ll also ask for your zip code.)
To view your card details, open your Lili app, go to the Main Menu, scroll down and tap on My Lili Card. You can start using your digital card as soon as you open your account. You don’t need to wait for your physical card to arrive. If you see it, you can use it!
