One of method atm for PIN verification is ANSI Pin Block. which is Ansi Pin block consist 2 blok, is PIN Block and PAN bock. PAN or primary account number Block is Acquire from track 2 on the magnetic card.
The Ansi Pin block has 16 hexa lenght and result from XOR operation from PAN block and PIN Block. for example we can see ilustrated below ;
From illustrated, we can see Pin Block. the component for pin block is ;
On Pin block
04 = ‘0’ is control field and always filled with zero
04 = ‘4’ is length of pin number
1234 = pin number
FF = padding character
On Pan block
0000 =PAD digit and always 0 value
589875200411= PAN Number, if less than 12 digit padding with 0
The result from XOR operation for PIN Block and PAN Block is 04126C678ADFFBEE.
This value must be encrypted with master key (stored on security module on ATM) before sending to the network.
For example the ATM use master key for encypted, and the value of master key is 1234567890ABCDEF. The result for this encryption is 953CC7CC0FC5BD7C
The result show on Test Key APP below;

hey EWIN
i want to thank you for this helpfull information...
i really need it, but i want to know how to get this Test Key application and NDC + Controller Simulator too, how can i ?
for ndc controller simulator you can find on sidecode.blogspot.com.
