The dot.card holds all your information on it once it's activated and linked to a dot.Profile. You can share your dot.Profile by tapping the card to someone's NFC compatible phone or by simply scanning the QR code on the back of the card.

All dot devices use NFC technology for instant transfer. All dot.devices have the same functionality and work independently of each other. They can be connected to separate dot.Profiles, or they can all be linked to the same dot.Profile. You can edit and update the information displayed on your dot.Profile as many times as you want.
