While there are many QR generator application available on the Net, I recently found a Business Card generator.  It is able to generate either VCARD or MECARD format, as well as a contact PDF sheet ready to send to the printer. (MECARD is a special encoding of personal information, suitable for QR Code Encoding.  This was popularized in Japan by NTT Docomo)

And, … it’s free

I tried it with QR Reader on the iPhone and found it particularly well integrated.  In particular MECARD can directly be added or merged to your address book.

Have Fun !
