You’ve probably already encounter QR Codes, these signs you can scan with your mobile’s camera to get some extra information about a product, a song, a TV program etc …
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 !
