Electronic business card. Continuation
The idea with an electronic business card does not let me go ...
I had to dig in the docks to understand how Mifare tags are arranged and how to work with them. But the task is completed and as it turned out, everything is not so difficult.
The picture for printing on the business card looks like this (I haven’t yet got the printer to print):
Although I planned to make an Android application first, but after thinking about it, I decided that it would be more appropriate to write an application for creating such business cards. Naturally, it turned out an application for Windows, with which you can write data to the Mifare Classic 1K / 4K tags.

Naturally, to work with the application, that is, to write a business card requires an NFC reader. In theory, the application should work with all NFC readers, but it’s only working with ACS reader ACR1222U:
Also, the logical continuation of the creation of a business card was the writing of an application for reading a business card and saving it in vcf format.

The output is a vcf-file, which can be imported, for example, in Outlook and other software that works with contacts.
It also came up with the idea to make a service where you can store more information, for example, a photo, resume, interests and so on ... And integrate this service into the application. This will allow the use of cheaper Mifare Ultralight tags, in which there is less memory, but additional contact information can be obtained from the service.
As before, we are working on applications for Android and Windows Phone.
An idea came up, to develop an NFC reader for the iPhone, but for now I’m driving this idea away, although it’s somewhere in the brain that itching is very interesting.
In the process of writing, I also thought to try to write the Credential Provider for authentication in the OS using the login and password stored in the Mifare card - but this is another story.
