That’s why the $99 Swyp, on sale today, with a limited number of $49 preorder units, and which is expected to ship this fall, looks and feels like a credit card. It’s thin, metal, and has a small digital display. It can hold up to 25 cards, and unlike purely wireless digital wallets, Swyp can be read by traditional credit card readers. Even better, Qvivr says, the card is secure and learns users’ behaviors, anticipating the card they want to use, based on time of day or location.
