Hi,
I've packaged up the epdq code we used in our system. This facilitates credit card processing into Barclays epdq system. A testpage is included to run the code. You need to register with Barclays and get an ePDQ client id before you can fully use this code. Documentation is included in the package. I'm not sure where I should send the package for general use, if you give me an email address I'll send it to you.
