Enabling multiple duplicate subsequent order processing

[VIPER7]

We have a problem with Able Commerce. If a person uses the same credit card for the same amount on the same day, able commerce will not accept the second payment.

This is a huge problem for our Vacation Bible School registration system that uses Able Commerce. We are requiring each parent to register each child individually, which means we could have 5 kids registered on the same day and the parent would use the same credit card for the same amount 5 times. Is there a way to turn off that feature of no repeat amounts?

Or, is there a better way that we could be doing this?

Thanks in advance for any assistance!

Who is your credit processor? Have you used gateway debugging to confirm it's not the gateway that is rejecting the 2nd request?

Agreed. Sounds like an issue with your payment gateway. AC7 doesn't care what card is used or how often - it only reports what the payment gateway tells it to report.

Certain gateways have a volume restriction to prevent flooding of charges on a single card. For instance, Authorize.Net will not allow multiple charges from the same merchant to the same card within 2 minutes of the previous charge. Any attempt to do so will respond with a "duplicate transaction" error.

Why can't they add the same product 5 times to one order?

Thanks to all who have replied to this topic. All of the discussion as to the logic behind why this is happening makes sense. We use LinkPoint as our merchant payment gateway processor, and I do indeed suspect that is where the issue is occurring, due to a security limitation / restriction they have in place.

I'll need to investigate further behind some of our reasoning for wanting each order to be tracked separately as opposed to say allowing 5 registrations on one order.

Thanks again and I'll keep us posted on this topic. I appreciate everyone's feedback!
