android send contact details to others

I was shocked to discover that this ubiquitous function isnt in Android in any flavour! WTF !

option 1 : get a pad and some paper...
option 2 : create a QR code from your contact to display on phone 1, and using the second phone scan it in!
find out how here...

option 3 : find an app
Of which there dont seem to be many. surprising really. but the best I could find is below, Seems to work well, but still doesnt sent it as a full business card boo.
