Support up to 18 and 19 digit credit cards

[lcastillo-evc]

Many of the major credit card carriers are moving or have moved to cards with up to 18 and 19 digits. Are you planning to add support for this any time soon?

Carrier Affected | # of Digits
China UnionPay | 16 - 19
Discover Card | 16 or 19
Maestro | 16 - 19
Visa | 16, 18 or 19
JCB | 16 - 19

Hey, @lcastillo88 I didn't know about that.
Thanks for reporting.

@lcastillo88 can you show some proofs about this, eg about visa? I tried to google something but didn't find anything 😞

I've found this useful article - https://baymard.com/checkout-usability/credit-card-patterns

@benhurott Pls check the PR #164, I'm not sure about some pieces, will nice if you can make a code review 😉

Hi @AleksandrZhukov thanks for finding an article about this. The truth of the matter is that I'm not quite sure when this new card length standard will be adopted but it would be nice to have this project support it when it does.

There is a nice lib that describes card standards - https://github.com/braintree/credit-card-type, I think will be nice to report new details or issues there
