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.

There may be phones that allow you to do this and there are also smart rings you may be able to use by cloning the card with a proxmark 3, a flipper 0 or other similar devices.
I see that my phone should support encoding NFC tags. I'll order a cheep ring and see if it works. Thanks.
I'm still curious though, why cannot phones produce that signals on their own? Isn't this what they do with payment apps?
NFC ≠ RFID
Payment apps are NFC
True... I confused the term, but this makes my question even more relevant. Since I have to put the card on the reader, I guess that it is an NFC card, rather than RFID. Which means that I should be able to duplicate the signal with my phone. I think.
Then again, what protocol does it use ? MiFare Classic then yes easy to duplicate.
Other MiFares? It will be harder/impossible.
I scanned the card using an app "NFC tools" It sais that it is manufactured by NXP and the protocol is MiFares 1k. Guess this hould work.
It's doable. Read thoroughly and you'll be good to go
Do you have a starting place? All I've found is instructions for copying NFC tags.
My phone with NFC died a year ago so... Take what I say with a pinch of salt.
If I remember correctly you can use NFC tools pro to emulate a NFC tag. It doesn't always work. I think it's in the write section then emulate.
There are however hardware limitations on emulation because of sector 0. Maybe try to copy your NFC card to a blank NFC tag (get it cheap on eBay) then if it succeeds go toward emulation.
Certain systems have clone card detection these days so you might run into issues
