I became kinda curious.

>>61180163
I don't see how it could push an advertisement without connecting to your device.

Sounds like bullshit tbqh

Right? The children here will sperg out nonetheless.

Bluetooth is the most likely option.

Uses Google nearby whatever that is and Bluetooth. I watched as video on their site

nfc is <30cm
Bluetooth is the only thing I can think of and it's going to probably be a pairing request with a url as a device name.

Stupid as fuck

>>61180352

Yes, it's bluetooth. It's basically abusing the broadcasting feature. This isn't a new concept.

Most devices would ignore it anyways, btw.

>>61180163
Is it user programmable? I can think of some great evil uses for that.

>>61180222
Pay for app developers to add your library or backdoor commonly used framework/library to have your adware in it.

>>61180403
What physically prevents NFC from working beyond 30cm? Like can't you just use directional antenna with high gain to get far beyond that? Or is that just RFID?

>>61181558
you will need to pay a lot of app developers and they would need to have a successful enough app for lots of people to download it.

don;t think they would want to give a successful app up just to let someone backdoor it.

>>61181584

So if I create my new encryption called "YouCanNotCrackThis" then no one can crack it?

What actually prevents it from working? It's fine if you don't know.

>>61181574
>near field communications

>>61181607
So what makes "near field" not be able to act from far other than name?

>>61181628
it uses an electromagnetic field

>>61181638
And why can you not generate field that reaches further than 30cm? What is physically preventing you?

>>61181655
at that point use bluetooth or wifi
not even power to drive such a function

>>61181673
>at that point use bluetooth or wifi
That wasn't even the topic of discussion.

Again why can we not interact with the magnetic field from further than 30cm?

>not even power to drive such a function

In the world? Or are you saying the phone doesn't have the power? But we are not trying to get the phone to do it. We are just trying to read the field created by the phone with external antenna that could be powered with a car battery for all I care, right?

Why do you keep insulting him?

>>61181825
You keep saying that, yet you still haven't actually explained why NFC can not work beyond this arbitrary 30cm (even though all the specs I've found so far say that absolute max is 10, but whatever)

>>61181842
By design you fucking pajeet shitskin

>>61181842
If I had to take a guess is that it would require some back and forth. So even if one device was capable of throwing a signal super far, if the other one couldn't there wouldn't be a connection. Or maybe its a problem of spectrum and signal degradation. I honestly don't know.

>>61181861
You still aren't answering his question. He's not even being rude, he's genuinely curious about how it works and you're just giving him a "it works because it works" answer. If you don't know the answer, then just say so.

>>61180163
How can I block those fuckers?

I'm seriously thinking about blocking nauthorized wifi/bluetooth devices now.

obviously any device capable of receiving such an advertisement would need voluntarily installed software on it. android isn't that insecure...

>>61181831
He's too dumb for /g/.
We can't be expected to explain to toddlers.

>>61181862
But if you have high power transmitter and high gain antenna couldn't you interact from way further than 30cm. Maybe not 100 yards, but maybe like 10-15?

>>61181842
NFC is a standard - ISO/IEC 14443. So basically it's outlined to work that way, the manufactures follow the guidelines to make the device compatible.
You can build a device that can transmit/recieve on 13.56Mhz with variable power output(Range depends on power, frequency and antenna design), but you might be breaking local law.

>>61181971
Or maybe, just maybe, you have no idea what you are talking about. You are literally just going based on the name of the tech with nothing backing yourself up.

You make it sound like this is the most obvious shit, but you still can not explain it.

I'm not sure most devices even display the messages though.
You can buy these for less than $10.

>>61181995
Ok well if you've read about NFC as anyone would assume you would before asking questions about the details of it. NFC has two sides to it. An NFC communication has an initiator and a passive side to it (the passive side is powered by the RF field the initiator generates). If you try to use NFC outside the specified range you probably won't have a passive side response strong enough to power the device. But it depends on the device. In theory you can reach 20cm as anon mentioned according to spec but that's a stretch. But for this application where you'd have a single device communicating with multiple devices it's not going to work because even if you manage to reach them all and pretend you're a passive device (there's no way you're a passive device at this range) you'd still have to make sure they can send whatever the equivalent to an ACK is in NFC. Which they won't. They're just cellphones. They don't have that reach.

And at that power you might power their passive NFC devices so if you could somehow make only one device respond to your signal you'd still be completely foiled by a stupid bus card being in the vicinity.

It's just not feasible at all to do communications like this. NFC fucks up if you happen to have two passive NFC tags close to each other when trying to read because they both try to modulate the signal and it comes out scrambled.

>>61180222
my guess: it works like an IMSI-catcher: interception of the control signal between cellphone and base station (it's radio traffic, after all).

>>61182179
So NFC has no identity in it? You are just reading data and hoping it's the right device?

Nevermind, it's just a pyramid scheme scam.

>>61182232
Yeah. It's not considered secure at all. Any 'security' comes from the proximity requirements. That seems to be something like 4cm on smartphones. After googling.

If you have a phone you can copy NFC key cards no problem. I've done it. Works great. Let's me get rid of the card and just use my phone.

But most NFC communication isn't used for purposes where the data is super secret. Tags are mostly for your convenience. When you want a link and not take a picture of a qr code. If you want a tag sticker in your home to enable certain settings on your phone by just swiping.

They're used for payment but that's usually in situations where even 30cm of mitm attacks would be hard to do. And realistically they could make the data sent be very temporal information. But I haven't checked what they actually send.

>>61182023
>hurr duhr my technical stuff
>doesn't know shit about physics
Kill yourself? Now.

>>61182023

I'm sorry no one is answering your simple question. I don't know the answer myself, to be honest, but I assumed it was because NFC uses electromagnetic induction. Magnetic field strength drops off very quickly with distance. I think it obeys the inverse-cube law, if I remember correctly. So that may be one reason that NFC is prevented by the laws of physics from working at much greater distances. You could amplify the transmission signal but you would need a ton of power - probably more than you can draw from a smartphone - to generate an EM field larger than a few inches.

I'm not sure if that's even correct but I just hated that no one was actually answering you so I thought I'd give it a shot. /g/ is retarded sometimes

Expect it was already confirmed (in this same thread) that it is technically feasible to communicate over greater distance.

>>61181598
if you know how an AC transformer works it's a bit like that
the primary is the phone and it induces a current in the secondary (the NFC thing)
wouldn't work with a big gap

>>61181748
Are you retarded? NFC is NFC not only because of power use but also because what device connects to what. The whole point of it is tap and go so you can use it for very specific instances like paying or getting a url for a webpage.

Not him but I use a bus travel card that I top up with my debit card. I was going to top up a card for a friend when I saw that the app didn't know any of my card details, I can only assume that this means my card details are stored on a third party NFC card. I need to test it further but this strikes me as secure as a child gate.

>I just hated that no one was actually answering you so I thought I'd give it a shot. /g/ is retarded sometimes
This. It was the equivalent of someone saying "I know the answer but I'm not telling you" which really makes me think they don't understand NFC.

And nobody is worried about the substantial security risk that imposes? That shit is basically getting access to your device.

>>61183270
>I need to test it further but this strikes me as secure as a child gate.
He is misled, NFC cards can be fairly secure with a secret key stored on the card and communications encrypted by that key.

>>61183387
Regardless, it was not stated anywhere in the app that I'd be storing my card details on a third party card, I had assumed that my phone was going to be handling my card details.

>I can only assume that this means my card details are stored on a third party NFC card.
You have no idea huh.

The NFC card is basically just a id. The reader sends a signal, the card sends back its id(like a card number) with a key to prove that it is that card.

The rest is handled by the reader, it checks your account balance in the database. They probably saved your card info there too, but definitely NOT on the card.

im fucking dying

im a GIS master's student. we have learned about this in our "location based services" class. at the moment it's a pretty big meme but it is one that big companies are researching.

right now phone firmware companies will find the exploits that are being used to deliver the ads. but that will not stop companies like asirvia from partnering up with other apps that people download and push the ads from there. basically the asirvia needs a willing vector into the phone. this could be a way for app developers to make money off of otherwise "free" apps

think like you are within 100m of a mcdonalds and you get a QR code coupon good for one hour to get a 50% discount on something. the ad is actually being delivered to you through your meme fitness app or some shit.

you may laugh but think about stuff like groupon - people will pay to sign up for services if they think they can get location-based deals forwarded to them.

Another spying technology by Google Botnet.
The Nearby thing isn't one-way communication. It relies on two Bluetooth devices to knowing about each other, then the beacon can push something to you, that your phone will use to query specific resource from Bootnet's server, and feed you with an ad.
In the end everyone wins, but you. The advertiser delivers an ad to you, the Botnet know when and where you have been.
It's not "they spy on my through my phone" anymore, it's "the phone spies on me".
And it's not that they couldn't do this in a better way, if they wanted. If they wanted that, they would implement it as the client being mere observer, not having to announce own presence, just sniffing on the digital ads in the air.

>>61181977
Yeah, there's a chance you'll fry any NFC chip you get too close too though. Basically both components need a magnetically induced voltage within a certain range. If you use a big antenna and a big transformer, your antenna will generate a very large magnetic field. If the NFC chip you're trying to communicate is hit with too much of it, then it probably would drive too much current through the chip's antenna and the chip would be dead.

What you're suggesting is more like an NFC microwave gun than a long range antenna

This is fucking beautiful
>Don’t surprise the user. Require the user to perform an explicit action (a button tap, going to a section in your app, a special switch, etc) to activate Nearby.
