> that I set online to exactly the amount I'm spending Sounds like it would take longer at checkout though?
Lots of my spending is online. Like everybody else, considering Amazon's success.

> You can't get 125 million folks into this address space? I think some people are now using a new card number per transaction , with these disposable card numbers, aren't they?
You're talking about services like Google/Apple Pay right? Aren't these credit card numbers rotated by Google/Apple, and they just keep some mapping of userIds, transactionIds, and rotated cardIds?

Why don’t we teach schoolchildren the NATO phonetic alphabet? Seems like it wouldn’t take that long, and it would be a useful skill for their whole life.
We should. There are so many adults who think it's cute to make up their own phonetics not realizing the whole purpose is to reduce ambiguity, not make it fun to spell things aloud.
Beyond assigning IINs more judiciously, credit rating systems could drop the concept of "more accounts = better credit". It would discourage people from opening 7 credit cards to raise scores, when 1 or 2 would do.

I have 4 unused cards I keep open just for this, seems a complete waste for every body.
Make sure to use them every once in awhile, otherwise the issuer may close them.
I wonder how this became a problem. Your CC number is not just 16 digits long. It's 16, plus expiration, plus the 3-4 extra security digits, plus your name, plus your zip code. That's quite a lot of entropy.
That's not true. The number is just the number, though it can be more than 16 digits. The initial six digits identify the card issuer. Expiration and CVC/CCV are security checks, but only work in combination with the number. Name is generally not verified, though is often used in fraud assessment. Address verification is uncommon, and almost unused outside the US.

Only slightly more insane than keeping the handy 4x4 format, but extending it from base 10 numbers to base 16, which I would really love to see :D
They would need to EOL over-the-phone payments to do this. People have horrible diction and it's hard to tell the difference between b, c, d, and e when a particularly lazy lipped person says these letters (in addition to non-hex letters like g, p, t, and v). Then they use their own ambiguous phonetic system (b as in ball, c as in call, d as in doll will confuse anyone trying to distinguish between the three). Oh and…
