What if they switched CC numbers TO IPV6 addresses? Insane or genius?

To what end? You want your card to be internet addressable? Also, I'm not enthusiastic about trying to communicate an IPv6 address over the phone to the wage slave working at the pizza joint. You'd have to implement one of those address-to-word setups, which would make for some amusing card "numbers". How would you like getting a card with "chinky challis uta ablow wiry rehaul a carotin" on the front?

Hopefully they keep the :: shortener in there....

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

  This is genius. Make this happen fintech.

  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 this compounds on ambiguous sounding digits like 13 and 30; 14 and 40; 15, 16, 50 and 60; 17 and 70; 18 and 80; 19 and 90). It can't be done with DTMF digits anymore either. All in all not a bad direction to go in. I wouldn't really miss phone payments.

    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.
      - jessriedel 6y ago
        As an adult who tries to remember the NATO phonetic alphabet but can't because I only use it once per month, I don't make up words "for fun" or "to be cute". I do it because I can't remember the NATO word. Compared to just saying the letters, the words I choose certainly do reduce ambiguity, even if using the NATO alphabet would go even further.

        This is mostly fine if only done for ambiguous letters and if the understanding is that it is done to reduce ambiguity. There is a contingent of people who painstakingly spell out every letter with a phonetic from their own system and it requires the listener to do a lot more decoding to the point of actually increasing ambiguity. "My name is Michelle that's M/N as in Nail/Mail! I as in Icecream! ..." Nichelle is confused about why we use words to spell out certain letters.

Why stop there? ipv6 license plates, citizen numbers, home addresses, part numbers, atoms, ...

  Do we have enough atoms?

    Don't worry, if we live in a cyclical model universe we'll eventually get some new ones.

  You joke, but that’s exactly what uuid/guid is — 128 bit identifiers. The only difference is that ipv6 is allocated hierarchically.
ineedasername 6y ago
Or just a UUID.

> What if they switched CC numbers TO IPV6 addresses? Insane or genius? Depends upon how it is implemented as could go full on 1984 very fast without that ever being intended. The whole aspect of a static fixed CC number you share with people is what really needs to change. A One Time CC per transaction would be more useful and negates many potential issues in a way that protects the customer and in turn the bank itself.

It generates a new credit card number for each transaction that charges the CC you have on your account. It's kind of like a password manager for credit cards.
  - gruez 6y ago
    AFAIK it generates a dynamic CVV. Your credit card number stays the same.

To addresses? Mostly pointless. To a larger number space that had non-numeric representation, genius and probably inevitable. If we allow for the representation to be 0-9 and then another ten letters selected for uniqueness and clarity, overlapped with appropriate non-roman pictographs, etc, the same 16 characters jumps to 600 quintillion range, or about 60 bits by napkin math. That's more than realistically enough for hundred billion people to each have millions of real payment IDs with millions more one-time use ones that contained some sort of transaction hash for authorization. Which conveniently fits in a 64 bit word with some left over. I suspect someone involved in the payment space already figured that out a long time ago, but no cataclysmic event has yet happened to de-rail the existing money train. If you wanted to do that in IPv6 you'd still have the upper 64 bits left over :)

If you want only identification, you can use a phone number, for some reason there's no problem with those.

Or implement NAT: make cards share the number, but identify them by their public keys.
