@t "Notes" of this length and pseudo-structure feel like they should be articles.

@jackdanger Thanks. It's happening to me on a bunch of sites. :(

@jackdanger It's the client side card number validation. It just refuses my number. I'm guessing that 48** doesn't fit in the regex.

@tadfisher I've had my card marked "invalid" on a lot of sites. I think their regex is too conservative about Visa numbers.

@tadfisher @simplify @square What two digits does your card start with 4*? Mine is 48.
