Chrome credit card autofill not being triggered
It will work if you add following attributes to respective input elements:
autocomplete="cc-number"autocomplete="cc-exp"autocomplete="cc-csc"
Also I noticed that Chrome will not autocomplete if one of the cc fields is missing.
You can play around here - https://jsfiddle.net/q4gz33dg/2/
Name your expiration fields card_expiry_month and card_expiry_year. I'm not sure why your current names don't trigger the regex, but changing the names seems to work.

Edit:Looks like ordering has to do with it too. If that doesn't work try putting the month/date immediately after the number entry field
The accepted answer is great, thought I'd just chime in with some documentation and a note regarding React (tagged for this question)..
React requires you to pass the attribute as autoComplete="cc-number" (note camelCase), otherwise it will default to autocomplete="off".
