Hi @FrancescoColonna! This is good! We've recently made changes to our BIN patterns and documented everything under CARDRULES.md. Do you mind adding tests in test/validateCardNumber_spec.coffee and possible source associated to the Wikipedia page?

Hi @ddayguerrero
i've added a basic test in test/validateCardNumber_spec.coffee and a reference to Wikipedia in CARDRULES.md
Please let me know if i can help in some other ways.
Thanks for your job!

Looks good to me! Before we move on, can we omit all generated distribution files from the list of staged changes? (dist/payform.js and dist/payform.min.js)

Hi @ddayguerrero i've removed dist/*.js files from staged changes.
Please let me know if everything it's ok.
Thanks,
Francesco

Sorry, I wasn't clear earlier. What I meant is to keep the files on disk, but remove the changes from the git change log. Something along the lines of doing git rm --cached

We should end up with 3 files changed:

src/payform.coffee
test/validateCardNumber_spec.coffee
CARDRULES.md

I truly appreciate your time and effort in creating this PR, but it is only best that we follow the guidelines shared by @jondavidjohn

Will close as soon #59 is merged
