Still distributing physical cards made from paper? Shame on you. How many trees should die just so you can etch your name on them. Eight (₹free on Android and iOS) is a business card organiser and a social media platform to connect with all your business associates. All you have to do is take a picture of your business card and the app will do the rest. Got a few business cards lying around? Simply take a picture and have it stored on the app in a digital format. Once the card is added, you can even add the person on your Eight social circle if they have the app as well. The in-app messenger and Facebook-like feed lets you keep in touch with those people too. So next time you go for a meeting, cut the bulk of carrying business cards. Just use Eight’s wireless card exchange method.
