Do virtual cards like these know when they've been swiped through a card reader? What if they allowed only one swipe when you're ready to make a payment? That way, if someone tries to skim the card, you'd get an alert like "hey, you just gave your card to somebody and it was read twice before they gave it back to you."
Of course, there are a situations where a multi-swipe would be legit, like the register doesn't read the card correctly the first time, or you make a last minute purchase ("you know, I think we will have dessert after all").
Maybe the card could detect the level of perspiration on the swiper's hand and buzz your phone if they seem nervous.
