r/NFC

Hello,

We are currently looking for a tag that is coaster like that we could orde about 20 for. Most places only have orders of 50+. We want it a circular design about 3 inches and everywhere I seem to go does not have that under 50 units. is there anywehere I can go? Or is it better to just make a custom coaster and slap a NFC sticker under neath? Thank you!!

The beginning of the end of one of my closest friendships started with the Dallas Cowboys.

Which is fitting because the Dallas Cowboys are essentially a federally unregulated source of human suffering.

I am a diehard Niners fan. Not casually. Spiritually. I hate the Cowboys with the kind of intensity normally reserved for white colonizers and people who microwave fish in the office kitchen.

So one season, when a Cowboys win over the Eagles would lock in the number one seed for the 49ers, I was forced into a kind of NFC East Sophie’s Choice.

This created a profound ethical crisis because rooting for the Cowboys felt like voluntarily participating in my own spiritual degradation.

And yet, because I believe in sacrifice, loyalty, and the pursuit of Lombardi trophies, I swallowed my pride and rooted for a Cowboys victory.

Not joyfully.
Not enthusiastically.
But dutifully.

A sacrifice well worth a Niners Super Bowl win.

Months later, I was at a bar with one of my white professional woman friends — a devoted Eagles fan — and jokingly asked:

“So are you still mad at me for rooting for the Cowboys?”

She glared at me with gritted teeth and said:
“Yes.”

I burst out laughing.

Because surely she was joking. Right???

She was not.

Then she said, plainly, firmly, and with an intensity I would normally associate with wartime resistance movements:

“I would never root for the Cowboys. I don’t care if it helped the Eagles.”

Because what do you mean you would not make a temporary emotional sacrifice for a strategically superior playoff outcome?

That is literally what loyalty is.

To me, rooting for the Cowboys was not betrayal.
It was tactical humiliation in service of the greater good.
So naturally I kept pushing the joke.

“Oh come on,” I laughed. “You absolutely would.”

“No.”

“But if it guaranteed the Eagles a better playoff position?”

She glared again.

“No.”

“But strategically—”

“Maria,” she said through clenched teeth, “I would never root for the Cowboys.”

At this point, I genuinely thought we were engaged in playful sports banter. Which, if you have ever met football fans, is essentially our native language.

Having lived in South Philly for six years — go Owls — I genuinely believed this qualified as deeply mediocre football banter one might casually exchange over a lager at McCusker’s.

Which made it particularly surreal to be accused of aggression by an Eagles fan from New Jersey operating entirely on theoretical Philadelphia energy.

Because suddenly she looked at me and said:

“Maria, you’re being really aggressive.”

Reader, I cannot adequately explain how confusing this was for me.

Aggressive?

I was sitting there discussing playoff probabilities and emotional sacrifice like somebody’s emotionally overinvested tío at a barbecue.

Immediately I started apologizing.

Naturally.

“Oh my god, I’m sorry,” I said. “I genuinely don’t want you to feel that way. What am I doing that feels aggressive?”

And instead she just kept repeating:

“You’re being aggressive.”
“You’re being aggressive.”

No clarification.
No examples.
No explanation.

Just the phrase itself repeated over and over like she was trying to summon Bloody Mary.

Shudder.

Or worse:

Bloody Karen.

Double shudder.

And now, somehow, I was crying outside a bar because my brain had entered a full input contradiction loop that only a Fireball shot could break.

The truly disorienting part was that once I became visibly upset and apologetic, the original accusation no longer even made sense to me.

The next day, she never called.

Mutual friends quietly stopped inviting me places because she “felt uncomfortable.”

Not because I yelled.
Not because I insulted her.
Not because I demanded anyone choose sides.

Apparently what had occurred was that I had accidentally violated one of the primary rules of upper-middle-class white woman social ecosystems:

if someone feels uncomfortable, the person associated with the discomfort quietly becomes socially radioactive.

I am the Dallas Cowboys in their story.

Ouch.

Which leaves me with only one logically consistent conclusion:

the Dallas Cowboys are a curse upon this earth, poisoning everything within their vicinity.

So hide your friendships, your playoff hopes, and apparently your cocaine.

Because unlike some people, I am apparently willing to spiritually degrade myself one “How ’bout them Cowboys?” at a time in service of the greater good.

So now I’m sitting here genuinely wondering whether I accidentally committed an act of interpersonal terrorism by repeatedly asking an Eagles fan to acknowledge basic playoff mathematics.

Was I unknowingly aggressive?

Did I violate some sacred East Coast female social contract?

Or did I simply encounter the first Eagles fan in recorded history unwilling to temporarily debase herself for postseason advantage?

AITAH?

Bang bang, Niner gang.

Good day everyone.
I want to ask whether those nfc payment ring/tags from aliexpress are any good. Can i actually use the to pay at checkout or is not compatible. I've tried to look for more reputable brands like astariwearables but either they don't ship to my country or they are too expensive. If you guys know which aliexpress nfc payment rings/tags are actually usuable can you please link them.

Many Thanks in advance

Im want to make a metal NFC business cards for my company and have been talking to a bunch of Alibaba suppliers.

My benchmark is basically the Amex / other metal credit cards. I know they’re technically hybrid cards (metal + PVC), but they still feel like pure metal to the naked eye / hand.

Most samples/videos I’ve seen online look pretty bad though. A lot of them end up looking like metal on one side and a cheap hotel keycard on the other.

I’m sure there must be suppliers/manufacturing methods that can get much closer to the feel/finish of an Amex-style card. Anything specific I should be looking for in terms of materials, construction, coatings, NFC setup, etc.?

Look, I know that a chip can store around 500 Bytes, and that the smallest possible 2 minute mp3 file is around 500 Kilobytes, which is 1024 times what an NFC tag can store. This obviously makes NFC tags impossible to use as a storage medium for audio files using conventional means. That being said, I'm interested if anyone knows any sort of hack or workaround for storing audio files on NFC tags. For example, LEGO has been using NFC bricks to store audio files by making their custom NFC reader have an onboard synthesizer which is capable of producing the desired sounds from simple text instructions on the NFC chip. Obviously this requires custom hardware, but it's fun.

My unrealistic goal would be to have a 2 minute voice recording stored on the chip, so that a mobile phone could download it off of the chip without an internet connection. Not needing internet is vital to this. I could obviously link to an audio file stored on an online content distribution service, but that's boring. I'd also like to generally avoid custom hardware or software, so that anyone can access the audio file without needing anything they don't already possess. This isn't that vital though.

Just how close could one reasonably get to this goal?

Would it be possible to create a way to tap an NFC tag and have it send random text from list of famous quotes?

I would like to create one as a button for my niece’s backpack which would then her a text of affirmation while she is studying in grad school.

I am open to other ways to display something or other ideas from you creative geeks :)

I have bought the NTAG424 nfc card and i would like to enable sdm and setup picc and cmac with a custom URL. Im fairly new to this, so my question is which software should i use for this, i have a ACR122U reader, ive looked online, but it seems like the TagXplorer from NXP will not work with this reader.

Did anyone else have issues with this? How did you solve it?

Any help is greatly appreciated, thanks!

Most of the time when people talk about NFC technology, it’s usually around contactless payments or digital business cards. I honestly never thought much about it beyond that.

But recently I walked into a small café and noticed a little stand near the register asking customers to “Tap here to leave a review.” I thought it was interesting because customers didn’t need to download anything or even search the business online manually.

I can see why businesses are starting to use them because most customers probably won’t take the extra effort later at home, even if they had a great experience. Making the process immediate seems more realistic.

I’m curious whether NFC engagement rates are actually better than normal QR systems or if both perform about the same in real-world situations.

I’ve been testing different NFC setups recently for things like Google reviews, WiFi sharing and social links.

One thing I noticed is that people seem much more likely to tap an NFC tag than scan a QR code, especially in restaurants or at checkout counters.

The interaction just feels faster and more natural.

Curious if others here noticed the same thing or tested similar setups?

Hii , I got a NFC tag but it’s not working. I’m trying to use. NFC tops app write to open an Instagram profile,it’s not detect the NFC, however the shortcut app is detect it and I can write on, so what should I do about it?
