I just read up on the IHK and it sounds like the equivalent for business that an employee pays to be a member of a union. The fee is 47 EUR + 0.14% of gross income, which is not exactly "significant" compared to the other fees, ta

It's interesting reading the comments here. When mobile (cell) phones first arrived in the US, they were a status symbol for rich people. When they arrived in Australia, the first adopters were trades people. They could be contacted an

Just reading all of this (I haven't used ligatures when coding), but the confusion between a ligature of >= and the Unicode ≥ (U+2265) could be handled by the language parser accepting either to mean "greater than or equal to&q

What you're actually saying is that when you use the standard language bindings for a protobuf parser, the type safety is as built in as your language. JSON has a limited set of types. There is object, array, string, number, boolean, a

How are you using this web site? The entire thing is "discoverable". What you're talking about is how can you publish a machine readable discoverable API. Just like RPC, there is no "well known" endpoint for getti

In other words, by using a RESTful style, with HTTP as the protocol, you get all the benefits of REST. The fact that you're using protobuf as the media type is irrelevant to the protocol. As for the content negotiation for JSON vs prot

Is the image/jpeg media type "typesafe"? How is using, for example, JSON Schema to define your types any better or worse than a "proto" file that requires a compiler, a parser, and a client and server library?

And the first thing that people do when they start using websockets is to define a message layer. HTTP is designed for transferring media types. It can transfer the application/octet-stream if you want to transfer "raw" binar

In other words, the signature is completely useless as a fraud prevention mechanism, which is why Chip+PIN was introduced in the first place.

by rswail 4y ago
I'd argue the opposite. In the US, the merchants had too much power to delay the introduction of Chip+PIN readers. The fraud of magstripes was huge, because there was literally no security. Anyone could create a magstripe. Customers

Very true, and if there's one thing about EMV, it is pedantic and convoluted and confusing, primarily because it has evolved and is not particularly subject to "intelligent design". :)

Unlike most of the world, where when a Chip+PIN or contactless payment is made, where the risk is transferred from the merchant to the acquirer/issuer. That was the whole point of moving to EMV, it removes the fraud risk from the merch

The difference is that in most of the world, merchants are required to provide at least contact ("Chip+PIN") readers and as of a few years ago, fully support contactless reading. It's only the US as a major environment that

I always get PII and CHD mixed up :) Sorry, to clarify: PII: Personally Identifiable Information (relates to GDPR etc) CHD: Card Holder Data (relates to EMV etc) CHD is a form of PII, but PII has greater scope.

If you use an EMV card in transit, then the Visa/MC rules say that the same card must be used to pay for the fare. Transit providers are not allowed to use the EMV card purely as "identification". I answered elsewhere on th

Yes, the DPANs have to be tracked separately so that you use the same device/card to enter as you do to exit. You shouldn't be able to see anything about the DPANs except the 6+4 information though and perhaps some detail of which

The DPAN is eventually detokenized prior to submission to the issuer for authentication and payment. So from Apple Pay wallet -> reader -> acquirer -> network -> issuer, the DPAN is used. When it reaches the issuer, the issuer d
