I am trying to understand data format and how information is stored? Trying to read it by microcontroller.

I found many different formats, is their any good website explaining this the format and background communication protocol? 

This is one protocol I found in NXP sheet.

But the data format exchange is not given, from where I can download this?

For payment cards, it's an ISO standard - isn't it?

 

NXP are pretty heavily into this stuff - you may be better asking on their forums ...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...

I saw this question from you on several forums, did you manage to find the answer? I would also like to understand, because I am interested in the technical component of payments and how everything works. I know from my own experience that if you urgently need money, it is much more convenient to use Fit My money , but for some reason many people use classic bank lending services, and I would like to know why. It is also not entirely clear to me how advanced the security system is and how anonymous the use of all these payment systems is. In general, there are more questions than answers. I would be glad if you share information.

He's not been seen on this forum in many years - suggest you maybe try one of the other leads.
