Heads up: AMEX cards now with 3-digit security codes This post is outdated

I just thought I'd give everyone a heads-up about American Express. They are now issuing cards with 3-digit CID codes on the front of the card. This is in place of what used to be the 4-digit code. Shopify's validation requires the 4-digit code to be input (as well as many other online merchants). Apparently I am not the first to have this problem because when I called Amex, they were able to issue me a 4-digit code. So now I have the card digits, the 3-digit code on the front, and the 3-digit code on the back that isn't used for anything, plus a 4-digit code that is not on the card anywhere that they verbally issued to me, but works as if it is the 4-digit CID code on the front. The reason I point this out is that your store customers may complain that your store isn't accepting their new Amex card. I am going to open a Shopify support ticket now, but I thought you'd appreciate the heads up that they will have to call Amex to get a 4-digit code. What I'm most concerned with is abandoned carts. Would be great if I could put a message on the checkout page but of course that is locked down.
