pin verify DA command problem

Nov 2, 2010 at 3:18 PM

I am trying to execute the DA command to verify PIN. I have used the same TPK and PVK from the PVV demo project and using the tcpworker.

I am getting a response code of invalid input and wondering someone can help me identify what I am doing incorrectly.


here is the winsimulator output.

=== [DA], starts 10:40:24.669 =======
[Key,Value]=[Account Number,407000025321]
[Key,Value]=[Check Length,04]
[Key,Value]=[Decimalisation Table,4561237897654321]
[Key,Value]=[Maximum PIN Length,12]
[Key,Value]=[PIN Block,028DCC093FB0471F]
[Key,Value]=[PIN Block Format Code,03]
[Key,Value]=[PIN Validation Data,12345N654321]
[Key,Value]=[PVK Scheme,U]
[Key,Value]=[TPK Scheme,U]

=== [DA],   ends 10:40:24.669 =======

output from my program


As you can see, I am getting return code 15(invalid data).

Appreciate any feedback!!!

The PIN block looks good. I've found out why you're getting a 15 back from the command but this is not the only problem. Allow me some time to look into it some more.

One more quick question, were you expecting a 01 (Pin Verification failed) response?

Nov 3, 2010 at 11:16 AM

yes, assuming there no other errors with command format.

Super, I'll post a fix for this in the next few minutes. BTW, what is the correct PIN?

Nov 3, 2010 at 12:45 PM

I don't know the correct PIN for this one.

I've posted the fix. Please download changeset 57015 and let me know if it solves this problem.

Hi Nick, could you also update the installer steup file with this new fix, becouse I dont have a Visual Basic 2008

Nov 16, 2010 at 6:15 PM

The installer for 0.9.2 should include this fix! If it doesn't please let me know!

Nov 16, 2010 at 7:04 PM

Yes, it is actually OK in this version, thanks a lot for your reply

Do you think that I can get installer as well for PVVClashingDemo

Nov 16, 2010 at 7:35 PM

The setup installers and the source code is due for a minor restructuring in the next version. If it's important to get the PVV Clashing Demo then please send me a private message and I'll figure out a way to send you the executable.

I love to get it soon if you can, How I can send you a private message.
