Another example of doing it wrong is when the form splits the cc number into 4 separate boxes, and automatically skips along merrily to the next box as you type it in. This might look nice and everything, but usually breaks if you try to backspace your entry, or paste etc

Also, dealing with AMEX screws up a lot of forms.
15 numbers, 4 then 6 then 5. Yes, only 3 groups. And the CVV2/CVC2/CID is on the front and four digits, not three.
I wonder if this has any thing to do with why amex was so infrequently an available payment option online for so long...
I doubt it. A more probable reason is the higher transaction fee charged by Amex (3.5% compared to 2%).

The demo form does seem to handle backspacing and pasting correctly.
I do know a LOT of places where this gets missed, and a typo goes to the next field, but reflexive backspace correction also fails.
