Merge - The only business card you need

Merge is an incredible way to share your contact details with people you meet on a daily basis. You can choose from whatever you want to share and change the details instantaneously, providing only the amount of information you want the other person to know. With this app, you do not need to carry the paper business cards anymore.
With Merge you can have a list of business cards and keep them all at one place which cannot be misplaced/deleted unless by your own will.
