CVK Pairs

Jan 2, 2013 at 11:27 PM

i understand how calculate a cvv with the source code for masters and visa but i don't understand the CVK pairs. Can you give more insight about cvk pair and if possible state the cvk pair for both visacard and mastercard. This is being used for project purposes.

I also did try some readup on it and i come up with this CVKA: B'0010'CVKB: B'0011' is there any other parameter missing from this.

Kindly explain more about the cvk pairs and be precise about what the pairs are.
