Ideally the person needs to enter the credit card number, expiration date in mmyy format (which is the format in which the expiration date is shown on the card), and the ccv number. The amount would probably be calculated on the basis of the outstanding amounts, or the products selected. Think of trying to buy a plane ticket or pay a bill. You are unlikely to want the caller to enter the amount. The thing is to structure the IVR in such a way that the caller is informed of the amount and does not have to enter it. If you take a far out case of a donation help line, you can simply go "for $5 press 1, for $10 press 2, for $20 press 3". If someone wanted to donate $15, too bad for us. If it turns out a lot of people want to donate $15, you can simply adjust the IVR (and of course the other logic).<br>
<br>This is a simple enough task. The big deal is supposed to be in ensuring that the date and the ccv number DTMF do not show up in any log files or trace files, and surely do not get logged by the application. You can simply turn off all DTMF logging, but you dont want to do that. Only the place where you accept the secure information, the logging should be absolutely turned off.<br>
<br>Getting the issue?<br><br><br><div class="gmail_quote">On Wed, Feb 18, 2009 at 11:20 PM, bilal ghayyad <span dir="ltr"><<a href="mailto:bilmar_gh@yahoo.com">bilmar_gh@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
And is there a bank accept to give such kind of communication?<br>
<br>
The user was able to dial his card number and the amount from his phone (or IP Phone registered with Asterisk), and Asterisk communicate with the bank or company credit card provider?<br>
<br>
How the user will enter $50.25?<br>
What about expiration date of the credit card?<br>
<br>
