Robin Good: CardFlick is a desktop and mobile app which allows you to design supercool digital business cards for yourself and to share them easily with anyone else with a mobile.
CardFlick offers 30+ beautiful business cards design themes that you can choose from, and you can easily personalize the colors and the information on your card. In addition you can use your favourite Instagram and Facebook photos.
Once you have selected your card, you can "flick it" anytime there is a nearby user using CardFlick, allowing you to share your personal card and to receive the other person info.
The great thing is that anytime you update your info on your business card, it updates also your digital copy that you have shared with other people.
Free to use.
