CardBin
On this page
The first 6 or 8 digits of a card number, which name its issuer.
Use it to look up a card's issuer or country, as fraud checks do. For the whole number, use PaymentCardNumber.
Shape
One value, held as text in one set form, with no parts: 42424242.
Example
CardBin("424242")CardBin(raw) checks the text, and text that isn't one breaks the format rule.
text.parse(raw, as: CardBin) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 4242, 4242424 or 424242424.
Good to know

In JSON
A string, in a request, a response or json.write:
"424242""42424242"
