RMS EDC Verifcation in DLL Via Hook

Hi, I am creating a custom hook for the Before Tender on RMS. I am using the Handheld TT8810. I am creating a custom hook so I can interact with the TT8810. I am just using the terminal to read the card, and provide a place to enter PIN/ Signature capture when necessary. I have a hook set up, so that when the user presses F12, my hook is activated. I have my hook find the "Credit" tender, and insert the appropriate information. I have not done anything but use the TT8810 as a card swipe. I would like to then verify via the "Preffered Acquirer" EDC in my hook. I want the cashier to then push the

key on credit, but I do not want the EDC screen to come up again, becuase I want to validate it before hand. I want my hook to use the built in EDC to verify everything, because I am having problems with cashier error. Hopefully this makes sense. Thanks for your help.

I really doubt that you're going to be able to tap into the EDC functionality. If you can figure out how to do that, you would NOT use Credit Card Tender Types - you would use "Other" types instead. Your Add-in would have to determine which of the "Other" tenders are credit card, then invoke the EDC functions (or more likely some other interface). You really want to do this AFTER the tender screen, not before.

You could save yourself a lot of time by contacting TPI Software - they have an Add-in that works with the Ingenico EnTouch1000, which is almost the same device as the TT31xx... I'm sure it would be less expensive to pay them to integrate a new device than it will be to build this yourself...
