In the US it’s cheap but unregulated

It’s the exact opposite actually.

US sunscreen is way worse than sunscreen in other parts of the world like the EU. It doesn’t block the harmful radiation as well. The reason is that it’s more strictly regulated in the US. IIRC it’s not considered a cosmetic product but instead it’s a medical product.

As such it’s subject to much stricter regulation and requires much more (expensive) testing before being allowed on the market. Due to this it’s considered too expensive to introduce the newer, more advanced sunscreen products in the US so you’re stuck with the older, crappier sunscreen.

Here in the Netherlands it’s expensive as well. Like a small bottle of name-brand sunscreen is €30.

I see flirting as banter to make sexual/romantic intentions known.

That’s basically what it is. It’s not there to make someone develop feelings, it’s a way to safely make your feeling known and see if they are reciprocated. It’s basically lowering the risk of rejection, if the feeling isn’t mutual and you don’t get a response you can just write it off as a harmless flirt. If (s)he flirts back you can dial it up a notch.

To add to this: The EU is developing this and it’s supposed to be available to all EU citizens at the end of 2026. From that time government services should also be able to accept it. (Not sure if they’re going to make it, the standards are still under active development).

It’s all based on OpenID Connect (OIDC). Everything is being developed in the open, as open source software. You can find the github project here.

If you want to take a look at the draft standards themselves, search for OpenID4VCI (standard for issuing of credentials to a wallet) and OpenID4VP (standard for presenting credentials to 3rd parties).
