Would verifying zip codes mitigate this issue, or do the carders have access to that too?

> is there a way to require someone to enter the pin that they use when they buy something in person A PIN can be required for "cardholder present" transactions in most of the world. Some combination of card issuer, transaction processor and merchant decide at what value transactions may proceed without a PIN — e.g. a train company's actual loss from a fraudulent ride is very small, so they might not want the delay o…

Newer payment terminals can support device-based customer verification for contactless transactions, called CDCVM. The transaction limit doesn't apply if CDCVM is used. This is the mechanism used by Apple Pay, where you verify your identity using your fingerprint via Touch ID.

#83I commented this on yesterday's jsbin article, and I'll write it again. Don't implement the payment processing code yourself. (And using Stripe is _still_ implementing it yourself - they supply only one part of the process.) Writing this code will take time that you are not using to develop and market your product. (cf opportunity cost). Your code will be buggy. Your code will be weak. Your code will not support the…
I'll keep trying to avoid using a creditcard as much as possible and use other payment methods when I can, both online and offline.
And yes, when implementing payments on a website, use a service that does all of the complex things for you, and never store sensitive data yourself.

3D Secure was mentioned in the other thread. Folks recommended avoiding 3D Secure / Verified By Visa because so many banks implement it insecurely, and the redirect model is easy for phishing scams to imitate: https://news.ycombinator.com/item?id=10235328 That redirect will kill conversion rates too, being redirected to a site you didn't expect claiming to be your bank but not matching its URL... of course it will fr…
These verification mechanisms don't freak people out once people are used to them. Pretty much anyone who uses credit cards to buy anything online in Europe will have encountered this system before and will be more suspicious if they don't see it! Using customers birthdate is indeed a very poor authentication mechanism, but even that is going to defeat the majority of fraudsters who are simply trying to bulk-authenti…

How do you use the collected birthdate to reduce fraud?

#86Interestingly enough I found this subthread from an HN Post earlier today to be very relevant: https://news.ycombinator.com/item?id=10234561 > Regarding his fraud issue, I found that my website was being used in the same way when I added a credit card payment form. I implemented a system that first does an "Auth". If that passes, then I pass details to MaxMind and get back a response with a "riskScore". If the score…
This issue is so costly and prevalent that I feel its a huge disservice for companies that offer credit card services to merchants to not either 1) mention this issue and recommend a fraud check service, or 2) include fraud protection in their service. I actually ran into an issue a little while ago in that I allowed my MaxMind account to run out of queries. Not realizing this, I saw a few days of higher than normal…
You may be interested in the system I use with my bank in the Netherlands.
The old system worked like this: The bank gave me a device they called a "Random Reader". To make a payment, I had to insert my card into the device, enter my pin, enter a (random?) number that the payment site gave me, and enter the amount. It then gave me a number back that I had to give the website, which authenticated me.
These days I use a "Rabo Scanner", which works the same except instead of entering a code and the amount it has a camera on there that scans a kind of barcode on the screen that contains that information.
So it does use the smart-chip, and the (8-digit) pin changes every time you make a payment. You do have to take the device with you, but it isn't very big.

#87Did you considered to accept Bitcoin payments? This way you wouldn't have to worry about chargebacks.

This is true but in this case he's not directly integrated (he's using Recurly). Better fraud tools is something we are actively working on.
I was thinking of using recurly and this has put me off somewhat.

Thanks for the clarifications regarding documents. To be precise, my confusion was due to not finding the Smyte brand mentioned anywhere in there, although I did admittedly only skim-read them. >Happy to chat more about specific use cases over a medium that's better suited to it; mind shooting me an email? Well, I could do that; I'm just not sure why you'd invite questions on a public forum and then quickly switch to…
The main reason is I'm going to sleep now and want to remember to get back to this thread tomorrow :)
