Cool, this is exactly what I was hoping to learn but couldn’t find. It sounds like its still a pretty manual process, but thats okay. If thats how it is righ now, then thats exactly what I want to know.

I’m considering making tools (GUI local app, but also website AUTH frontend/backend tooling) to try and make systems like this more commonplace and standardized. I didn’t know about revocation keys, so I’m glad I heard about that before trying to build my own.

Nailed it

Yeah, sorry I incrementally edited the title before posting and accidentally made it make no sense. I meant publicly announce that a private key was compromised

It gets worse :/

I looked up the brand (Invenda). Their PDF includes “using AI”, “measuring foot traffic”, and gathering “gender/age/etc” e.g. facial recognition to estimate a persons age and gender

And in terms of “stored locally” this is straight from their website

The machine comes with a “brain” – Invenda OS – and is connected to the Invenda Cloud, which allows you to manage it remotely and gather valuable environmental, consumer and transactional data. The device can be branded according to your requirements to further enhance your brand presence.

The marketing also so fricken backwards that it reads like satire:

For a consumer, there’s no greater comfort than shopping pressure-free. Invenda Wallet allows consumers to browse, select and pay for products leisurely and privately 🤦‍♂️
