"Convenient Business card software fro Mac."
great templates library, document background and front layer, label formats
i don't know exactly.
It's a new software from Cristallight. There are a lot of manufacturers sell paper for business cards printing. Also you have ability to import address or contact data either from the built in database, or, what is even better, another application like Address Book, etc.
You can encode urls and add them to your card as qr code object, or even get all the contact information of a given person encoded in a vCard format.
