The one which best fits your requirements!

The mfrc522 will probably define whether the nRF51822 needs to be the master or slave.

Go to the Nordic Home page, and click on 'Support':

It's also linked from the nRF51822 Product Page:

Yeah I know how spi works but I am interfacing rfid mfrc522 with the nrf51822 microcontroller.which one will be better code in that documentation to implement this and how can I understand Is there any easy way for that,and yeah I know Embedded c .By the way where can I find that sdk documentation.

What is it, exactly, that you don't understand?

Are you familiar with the basics of how SPI works?

Are you familiar with 'C' programming and microcontrollers?

As Kenneth says, have you looked at the SDK documentation?

It's hard to make suggestions when we don't know where you're stuck, or what background you have.

I would think looking at the online SDK documentation and look in specific at the SPI example and SPI driver documentation would be a good start?
