I've been looking around various different places to see if there are any good fraud detection tools or techniques that I'm not yet using but should.
I of course already have minFraud set up within Foxycart and all the fraud detection settings with my gateway.
On top of that I built an integration with Signifyd, very easy to do and free if you put their logo on your site. So far that has been our favorite tool, thanks @markbahl
What I'm finding on other sites is suggestions to contact the card issuing bank and request that they place a curtesy call to the card holder if you believe the order is fraudulent. I was wondering if anyone here has tried to do something like that. Right now I don't have a way to know what bank issued the card so any suggestions on that would be appreciated as well.
