"The biggest hurdle in the negotiations was likely whether the new means of payment should function exclusively online or also independently of an active internet connection."

How can this even be a question? As long as governments don't give me free internet access and the minimum of required hardware making it online only would be rediculous. Either it's a working system for all citizens not just those who can afford it or it's a conceptional stillbirth.

It is technically impossible to make it function without the internet. It's called the double spending problem and it can only be solved with some sort of global consensus state

How do banks work then? Transfers in cash? Or does that global consensus state in fact not rely on realtime communication?

[-] Mubelotix@jlai.lu 1 points 7 hours ago

Banks form a network. Information is easier to copy than raw materials. Optic fiber is fast you know

How do payments on planes work?

[-] wizzor@sopuli.xyz 1 points 7 hours ago

Poorly. The transactions clear when the plane lands, and this is a significant headache for airlines. More modern airlines have satellite internet onboard for this purpose, but it costs a lot to install on an airframe.

Source: worked in payments and asked an airline head pilot.

You can scam the company, but if you do they know who you are and come after you. Which is not compatible with privacy

Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in other communities.
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media (incl. Substack). Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the admin that applied the rule (check modlog first to find who was it.)
