No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

At my job we recently got 15 plastic cards with an NFC chip. Scan the card and you go to a page where you can add the info to your contacts. There's a qr code for when NFC is disabled and too complex to turn on for some people (i.e. CEO's and the like).
This being Lemmy, this'll probably get comments like "never scan an unknown NFC tag blah blah blah"
Why is NFC needed in this case? Regardless of this being a potential security risk (which it is, but it's not my point here), does it provide any additional value over a QR scan, which can easily store a URL or a contact information?
Contact images, perhaps? Or maybe just aesthetic purposes with however they're choosing to distribute their contacts, and don't want to paste QR codes in places. For contact transfer, I don't think there's much technical advantage to using NFC over a QR code, since QR codes can fit a lot more data than most people realize.
Not needed, but convenient. NFC is enabled by default on most phones so all they have to do is touch the card.
I see your point, but seems the same effort as a QR scan
NFC: hold to card, done. Qr: unlock phone, open camera, scan, confirm opening link.
Granted, it's 4 seconds vs 0,5 second but still.
