Allowed lengths for visa: 13, 16, 19

@Yottster OK. I was unaware that there are 19 digit visa card numbers. Personally I have never come across one but either way if card.js supports the input of 19 digits it should handle 19 digits in the preview without wrapping them.

Ugh yeah, this needs to be fixed. Renaming to be more clear.

Would love to accept a PR for this change. If anyone is interested in contributing this in, I think the best solution would likely resize the text size of the card number field once its goes past 16 numbers. A library like textFit could be used.

Is there a way to limit Visa to be 16 characters ?

System like Cyber source doesnt allow Visa card to be 19 digits

@tonywong625 It's been a while, but if you need to, it's pretty easy.

card.js: https://github.com/jessepollak/card/blob/master/dist/card.js#L1087

jquery.card.js: https://github.com/jessepollak/card/blob/master/dist/jquery.card.js#L1133

Just remove the ", 19" part. All of the card validation is done in those areas, so you can make any other changes you want, although I've only found the 19 digit visa to be an issue.

I dont want to edit the core js, would be better if there is an option to overwrite it imo.
