Ok, just discovered this site, and it seems cool ! But when I try to buy something with my credit card it says this:

Your credit card could not be authorized
Your credit card number was invalid; please input a valid credit card number, expiration date, and provider below and then proceed.

Well I put in a valid credit card number, and a valid expiration date, but there’s no place to put in the provider thingy ! And yes, I am 100% sure that there is enough money available on the card.

This is stupid! please help

Hey Alkohoel,
Hmm… That seems fishy.  I can’t seem to recreate it on this end and have seen several credit card purchases going through this morning.  Hence, can I get a bit more information from you and hopefully we can get it figured out and fixed for you:
1. Did you, by chance, change your order mid-way through the purchase process?
2. What type of credit card provider (Amex, Visa, MC, Discover) are you using?
3. Did you include dashes or periods when you typed in your CC number or did you just type in a long line of numbers with nothing breaking them up?  If you included anything, can you try it without anything punctuating the numbers?
4. Are you using a US or non-US credit card?

I’ll also follow up via email!

1. No
2. I use visa
3. I typed a long line of numbers without anything breaking them up.
4. I’m using non-US credit card

One thing that I noticed from this website is that you don’t ask for the 3 numbered security code on the credit card, it might have something to do with that in some way.

Thx for your help !

Different credit card payment processors use different security protocols.  Ours doesn’t require the security code but looks at other attributes of the purchase.  So, we’re safe ruling out the security code but obviously still have a problem.

My best guess is that this is an issue tied to the int’l status of the credit card, but I have had several int’l visa charges go through fine today.  :S I talked to someone on our development team about how this works.  There are a few different tests of credit card numbers that credit card systems walk through in order to determine whether a card number is valid (before even trying to charge the card and determining whether the charge is allowable from a balance standpoint). 

For VISA, they look at the first digit of the credit card number and the total number of digits in the credit card number.  Last, it does a numeric calculation (the Luhn Check - http://en.wikipedia.org/wiki/Luhn_check) based upon the digits and order of digits in the card number to verify that it is a valid card number.

There’s not a good way for me to look at your credit card number to see what might be tripping the invalid trigger, but can you confirm that the first digit of the number is 4 and the full number is 16 digits long?  If this is the case, then the error is tied into the Luhn algorithm.

PS I emailed you earlier today to let you know that we added some complimentary credits to your account.  Hopefully you can use those while we get this working for you.
