Sending a individualized business card is simple if you use vCardSender2 from the AppStore.
Open the AppStore App and search for "vcardsender2".
Or check out: facebook.com/vcardsender2 for the AppStore Link.
vCardSender2 is also available in a free lite version. (The lite version is just without the ability to search a contact.)
After starting the app just find the person you want to send.
You can just tab the person or use the search function.
After selecting the person, you see the saved (just the important) details. Separate in a "private" and a...
... "business" category.
Now you can easy select the information you want to send (or not) or edit them. If you edit a information it won't change the original contact in your device address book!
If you'r done, just select "send" to send the card.
That's it! The receiver will get the individualized card. The card is working just fine with all platforms.
I'm the developer of "vCardSender2". If you have questions, just ask. And if you miss something in the app, let me know about it. I will try my best to upgrade the app with your ideas!
