Stripe - Amex CVC/CVV length

Hello @Glenn,

I’ve just got an email from a client having trouble paying via Stripe using his Amex card.

Looking at Stripes logs, it seems to be failing the CVV check - and on further investigation, it looks like the Amex card has a 4-digit CVV rather than a 3-digit one.

The QF Stripe popup only allows one to enter a 3-character value into the CVV field.

Any chance you can expand that to accept 4-character values such that the Amex’s CVV can be entered?


Yes I see here that Amex cards display the CVV on the front rather than the back and are 4 digits long.

It’s a very simple change that we have now made on the live service, so it should work fine.
