Electronic Business Card Service

I bring to your attention a small service that allows you to generate a QRCode for placing it on a business card. This will make it easy to 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 was very large and it was not always read.
As a result, I came to the conclusion that the easiest option to implement is to store a business card online (for example, in vCard format ), and put only a link to it in QRCode.
A service was written in 3 hoursvcards.ecm7.ru , allowing you to do all this. The service is an application on ASP.NET MVC, MSSQL Express is used to store data, to access NHibernate data. The layout used Twitter Bootstrap and the background image from here .
The library for generating QRCode on .NET was found here .
In general, this is all I wanted to talk about. I would be glad if the service is useful to someone.
Threat. The result is something like this .
