A lot of payments chatter on here recently and patio11 throwing out some great content as well. May I ask where this pretty visual explanation website was 25 years ago? ;) Oh the woes of programming ISO8583 as I see another commented on EBCDIC which adds in a whole other level of mind numbing when passing between the endians. It was a fun experience however back in the early 2000s when I worked in isolation with Discover card to get the GUID field added to the ISO8583 specification.

We are living in changing times on many fronts and the worlds financial systems is one of those new battlefields. Many are ignorant as to what is occurring but with big tech owning their own payments ecosystems this should be insight for others not aware as we are absolutely certain to see more following their lead. Some of those others following are entire countries, they are just a bigger business after all, as it is already happening for those aware and a small select few are doing i.t.

Stay Healthy!

Painful memories of when you tell brands your data is coming in as ASCII and they have it as EBCDIC.

I referred to it as "the woes" but yes I agree with your choice of words as well. As an experienced technology builder I generalize the struggles I vividly recall and it often involves parties not doing the real work and therefore they lack the comprehension of the details that are all that truly matters. This applies to a lot of things today, tech included, where most have no idea how anything works and the solution typically boils down to, did you power cycle it?

I learned a lot more about this discussing the PCI/DSS [0] regulation framework here [1]. It's about to change to a new 4.0 in 2025 which means that to use or run any payments system you'll have to meet ever more stringent regulation. This is going to start applying to other pseudo currencies (in game value tokens etc) if they exceed certain value and scale. At present Visa and Mastercard have a big stake in defining this (capturing the regulator).

Interestingly local real (non-digital) currencies like the Brixton Pound [2] and other local paper scrip seem to escape this, which seems a boost for paper technologies.

PCI-DSS is an industry standard, not a law. If you don't think it should apply to your domain, complain to your legislators/regulators, not the authors of PCI-DSS or the payment industry covered by it!

And so do countless other digital (non-real?) payment systems across the globe. That's not to say that there aren't any other security regulations, but they're also most certainly not in PCI scope.

Arguably, the original sin of the card payments industry in particular, and US American banking in general, is treating account numbers as bearer tokens, i.e. secret information; if you don't do that, it turns out that a lot of things become much easier when it comes to security. (The industry has successfully transitioned of that way of doing things for card-present payments, but for card-absent, i.e. online, card transactions, the efforts weren't nearly as successful yet.)

There is some confusion in that comment.

- PCI DSS 4.0 is already in place and to be retired on December 31, 2024. PCI DSS 4.0.1 is the replacement and I place already.

- PCI DSS 4.0.1 and game tokens have nothing in common. The applicability of PCI DSS requirements are decided by card brands, aka Visa, Mastercard, etc. And it is the acquirers to enforce on the third party service providers to enforce the standard. Standard itself has no power on anyone.

- Mastercard and Visa have high stakes because technically they are the regulators. EMV Co, the core of the payments was built by Europay (later acquired by Mastercard), Mastercard and Visa. The M and V of it are managing the chip on cards, online payments and much more. PCI SSC is merely a supervisory authority who sets the standard, the process of assessments and investigations on behalf of these brands.

Side note: While the other card brands accept PCI DSS as an entry level requirement, they do not have as much saying on it as Mastercard and Visa.
