Electronic business card service

I offer you a small service that allows you to generate a QRCode to place it on a business card. This will allow you to easily save information from your business card, for example, to your phone.

Some time ago I read an article whose author suggested placing QRCode on business cards. I really liked the idea, but when I tried to generate a QRCode for my business card (putting all the information from the business card in it), it turned out that the result is very large and it is not always readable.
As a result, I came to the conclusion that the easiest option to implement is to store the business card online (for example, in vCard format), and in QRCode place only a link to it.

For 3 hours, the service vcards.ecm7.ru was written, allowing you to do all this. The service is an application on ASP.NET MVC, MSSQL Express is used for data storage, for accessing NHibernate data. The layout used Twitter Bootstrap and a background image from here .
Library for generating QRCode on .NET found here .

In general, this is all I wanted to talk about. I would be glad if the service will be useful to someone.
