[Nexus S General] Chinpokomon:
Yeah, the security implications would be my concern. The card readers don't show anything... I wonder how you'd be able to use a phone to pay for things in the future, as that was the suggestion given when the Nexus S was launched. Seems like transmitting is a whole different problem.
[Nexus S General] kaine13x7:
This is why nfc is utter fail. Sure its encrypted but any 15 dollar portable reader off ebay will be able to get the info. It would be impossible to encrypt it to the point of not being a theft risk, because then you would not be able to use it at the pay point scanners...
[Nexus S General] :
You know how your wifi doesn't have to be on all the time?

It's called toggling and user initiation.
[Nexus S General] waruwaru:
Got the "unknown tag" when placed on one of those Japanese Suica cards. At least now I know the NFC is working...
[Nexus S General] jokinawa:
The more I read this the more I think that you will link this to a Google Checkout account to buy stuff.

Over here (Japan) as far as I know I can only use my wifes Japanese phone with NFC to buy stuff. The NFC is probably looking for a valid vendor ID and not another purchaser ID (Credit Card w/NFC, Passport, etc.) I don't think, without some major hacking that the NFC will read non-vendor NFCs.

The way I use it here is as follows:

1. Go to any convenience store or grocery store and go to the checkout with you stuff.

2. After the stuff is rang up and the cashier tells you your total the buttons of the different NFC companies blink.

3. You pick your NFC type. And press the button while holding your NFC within the readable distance.

4. After a sec it validates that you have the cash on the NFC acct to pay.

5. If you do it makes some sort of noise to indicate success.

6. You walk out with your goods and enjoy.

Its actually very nice not to have to carry your whole wallet.

The only downside is with the pre-paid ones you can charge at the register with cash is there is no validation that the card is yours so if you lose it you lose all the cash on it.

Not sure how it work with a phone version.
[Nexus S General] Chinpokomon:
Maybe. I was surprised that the reader didn't have some transmitter that would cause the phone to start transmitting, but maybe I'm thinking about the usage in the wrong way. If there were "cards" at checkout that the phone could talk to, it makes sense that it may cause the phone to make the transaction. I don't really see how that would be all that different from purchasing an app from your phone.
[Nexus S General] gietl:
Huh, wondered why I kept getting an unknown tag notice. Must be my Citi Card i Know it is supposed to have a paypass like feature though I have never used it.

I often set my phone on my wallet.
[Nexus S General] codebutler:
I'm working on an app to read ORCA cards. It's not quite ready, but hopefully I'll have something for other people to try by Christmas. The app will be extensible so people can add support for other transit cards too.

The documented NFC APIs included in Gingerbread are a tiny fraction of what the underlying system supports. The Nexus S is capable of transmitting and receiving, emulating a card, and talking directly to another phone (to exchange vcard data, for example). Looking at the code, most of this appears to be fully implemented but for some reason not part of the SDK. I don't expect it will be long before people start releasing apps that enable these features.
[Nexus S General] Chinpokomon:
Awesome, I'll be sure to let you know how it works for me when you release it.
[Nexus S General] stonew5082:
hey, it worked for me last night. A couple rug shops in my area (god knows why) have nfc google posters hanging. So I placed the phone next to one and it showed the name of the shop. Then it took me to some random google places webpage. Maybe the shop owner didn't know how to program it... But it worked! Kinda disappointing, actually..
[Nexus S General] sargasso:
Although I think NFC has many uses I do not see anybody discuss the social / practical aspect of it.

Where I live people don't really appreciate other people playing with their phone while engaging in life social events. Having access to more/specific information on a product then others while being in the same shop does not compute to me as a benefit for selling more. Also I already see people stopping in their tracks and blocking a pathway whenever their phone demands attention. Imagine people browsing the internet in your shop ...

I like to have an NFC chip on the outside of my shop for when it's closed, although google goggles, google maps, layar and other apps can provide the same service.

Paying with nfc? Not untill when in europe?
[Nexus S General] jokinawa:
How about having an NFC reader on your PC/Laptop and using your phone for authentication?

That would be pretty sweet.

Or better yet, a door lock that can use NFC or a key similar to some cars now.

Still, payments and advertising will be the largest uses for a while. Some uses here in Japan are payments, membership rewards, advertising, etc.
[Nexus S General] selectormoldy:
Has it dawned on anyone that NFC could be used in lieu of dock connector pins? (launch Car Home, Desk Clock, etc.)
[Nexus S General] songsterq:
Hi codebutler, any progress with your app? I was playing around with the NFCDemo app coming with the SDK. I debug into TagViewer.resolveIntent(), the following line will always return null when using an ORCA card.

Parcelable[] rawMsgs = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);

and the NdefRecord produced later in the method has an empty payload. Same thing happens when using the "Top connection" key tag from top food. Any hints on how to read these tags?
[Nexus S General] thepro8:
To test nfc right now you can. Buy some pre-programmed NXP mifare 1k or 4k tags. We have nfc business cards that the nexus s can read
[Nexus S General] thepro8:
Yes, it can be used to initiate a connection and then you can bridge easily to a faster speed wireless connection
[Nexus S General] thepro8:
With the correct software implementation nfc payment is VERY secure. Its pretty easy to make the software correct too.
[Nexus S General] thepro8:
correct, but without an api you need a key to access the payment portion of the nfc chip. This isn't available for the nexus s.
[Nexus S General] ritcereal:
I've been playing around with the built in NFC demo in the SDK and specifically with TagViewer.java, however I can't seem to get anything from the Intent provided when testing with a normally Unknown Tag.

Has anyone gotten past this? Looks like we won't receive data from sources that are not properly formatted...but since it has an RFID reader there must be a way!

[Nexus S General] w1nter456:
may i ask does NFC chip has radiation ? and does it affect health?
[Nexus S General] thepro8:
Nope it doesn't
[Nexus S General] w1nter456:
can you tell me why?
[Nexus S General] deeren:
If by radiation u mean radiowaves.then yes it does.

Is it harmful? surely not.
[Nexus S General] codebutler:
Hey everyone -

Sorry this took so long! I just posted code for FareBot, an application that can read MIFARE public transit cards using the Nexus S NFC radio.

It currently only really supports the ORCA card (used in/around Seattle, WA) but is designed to be extensible and will hopefully support other cards (such as Clipper from the California Bay Area) soon.

http://github.com/codebutler/farebot

The app is still still very much a work-in-progress, but let me know if you have any problems or questions!
[Nexus S General] kenvan19:
Because 1) cell phone "radiation" is a myth. No one has proved that any type of cell signal has any sort of adverse side effects and for every study that claims to have found out for sure this time there is another that can prove it is beneficial. and 2) the fear of technology is based on fallacy and misunderstanding. The government fears new technology because it gives people the ability have more access information which is the most dangerous tool in the world. There is absolutely nothing to fear in cell phones, except of course, the bills.
[Nexus S General] kenvan19:
By reads, do you mean it can't actually be used for anything practical right now? I don't mean to sound rude, I do very much understanding getting the hardware to just read is an important step to getting it to be able to work universally, but I just wanted some clarification (mostly since I live in/around Seattle and being able to swipe my phone would be sweet).
[Nexus S General] codebutler:
Correct. The phone does actually support emulating cards, but that's a whole other project.
[Nexus S General] Lord_Buckington:
I don't live in Seattle, but I'm excited to see people like yourself working on NFC apps! I assume this will be possible with similar systems such as Oyster in London

Sent from my Nexus One
[Nexus S General] kenvan19:
Either way man, great job. Happy to see some work getting done on this!
[Nexus S General] codebutler:
Yes! I don't have one but according to Wikipedia, newer Oyster cards use the same technology (MIFARE DESFire) as ORCA. FareBot should be able to display all the data stored on the card even though it won't know how to make sense of it. If you have a Nexus S too and have a chance, give it a try. Here's a prebuilt apk:

http://dl.dropbox.com/u/918489/FareBot.apk
[Nexus S General] :
Cell phone radiation is not a "myth".

It's there, in small quantities. I haven't seen any recent studies since mid 90's, and the amount of cellular waves that we are being exposed to compared to the timeframe the initial study was done, has multiplied significantly.

Because the exposure was so small before it was overblown, today it's a whole different ballgame.
[Nexus S General] Waza_Be:
Happy Nexus S users, time to write NFC has come:

http://www.nearfieldcommunicationsw...n=Feed:+nfcw+(Near+Field+Communications+World)
[Nexus S General] kenvan19:
Note I said "radiation" as the "radiation" being referred to is not the radiation of radioactive isotopes such as Uranium or Plutonium or many other heavy metals. It is actually an amount of the radio waves our bodies absorb while using the device. Here is an article that talks about it. Now go into their table and tell me what negative side effects have ever been proved to exist from the highest emitter in the country the Motorola Bravo (1.59 SAR). There are no definitive answers and the burden of proof lies with those claiming that it has negative side effects and I've never seen anything that proves it. Therefore, it is a myth.
[Nexus S General] :
Those very same reports are proof of radiation being emitted. Again, the quantities at the time weren't sufficient to cause any real concern. The rapid growth of adoption in the past decade requires new data.

Until someone turns up a time machine we won't know the long term ramifications of being bombarded by radio signals 24/7.

Those FCC tests are your proof that these radio waves are harmful, which is why they have limits as to how much you can be exposed to.

You know they used to think xray machines weren't harmful either, right?

Believe me, I've had discussions about these things with science professors(in the medical field) that know what they are talking about, being exposed to all these wireless frequencies constantly is NOT a good thing.
[Nexus S General] kenvan19:
There was also a time when cigarettes were considered healthy. And when treating illness with medication was considered heresy. Science can be wrong. There are doctors out there right now who graduated from medical school and still will tell you that HIV does not cause AIDS. The FCC you are referring to is the same one who believe that allowing children to be subjected to extreme amounts of violence is fine but allowing them to see even the slightest amount of human sexuality is disastrous and the laws that have been passed in some states regarding cell phone SAR are been passed out of fear, not fact. There are no facts on the subject, only fear. The same fear that caused Galileo to be executed for his beliefs and the same fear that allowed Eugenics to be a valid field of study.
[Nexus S General] Lord_Buckington:
Thanks, good to know!
[Nexus S General] :
What are you on about? No facts? lol

Wireless signals ARE by definition radiation. You are pushing all kinds of atoms through concrete and steel structures, and you think those things won't affect out soft tissue? There are no long term studies to show that these signals are harmless. These technologies are infantile, and there's more evidence showing they can be harmful than there is that they are harmless.

I won't touch on the nature of FCC ratings regarding appropriate contect as those are subjective, but do not try to use that as some kind of argument against proven scientific testing about what is being emitted from electronic devices.
[Nexus S General] kenvan19:
The same sort of fears about cell phone radiation were brought up about the radiation from microwave which have subsequently debunked and yet the FCC still maintains standards for the amount of radiation leak allowed. Look man, I don't want to get in a flame war with your over this, I'm just sick of people crying wolf over the "hidden dangers" of cell phones when there is no universally accepted studies that prove any sort of long term effects and I haven't found anything on followup studies to the ones in the 90s which would provide a better look into said long term effects.
[Nexus S General] :
There's a difference between a study not finding long term effects, and no long term study being done. Long term means ongoing, like I said this tech is very very young.

Are you implying that microwaves aren't dangerous...........because they are horribly dangerous if a device isn't shielded properly.
[Nexus S General] kenvan19:
Twenty years (I'm counting from the early 90s because while cell phones existed in the 80s, they were not widely used until the 90s) is more than enough time to study its longterm effects and as to microwave radiation, the danger comes from the heating effect of the waves and not the waves themselves. The idea that the waves cause cancer has been debunked.
[Nexus S General] kenvan19:
Stanford researchers demo social NFC applications on the Nexus S

=O I want to use themmmmmm lol
[Nexus S General] :
....Old studies =! long term studies....

Alpha and beta particle transmissions IS NOT GOOD for soft tissue. I'm not writing this as an argument, these are facts from HUNDREDS of studies and books upon books of medical and scientific research. I'm stating things that have been repeated to me by PHD professors, doctors, nurses, and scientists IN THE MEDICAL AND SCIENTIFIC field, backed by research.

*expects your next post to be from snopes.com*
[Nexus S General] herman3101:
EM Radiation isn't inherently dangerous. Visible light is a form of radiation and most would consider that to be pretty safe.

Microwaves have much lower energies than all forms of light (including IR and UV). The only potential danger is the thermal effect as a result of dielectric heating. The SAR values show how much localised heating occurs and it is very low. A mobile phone puts out a peak power of 1 - 2W. A microwave oven puts out a constat power between 600 - 2000 watts

Microwaves do not have the power to ionise tissue, which is the reason higher energy EM waves are carcinogenic.

Alpha and beta particle emission, as hinted, are sub-atomic particles that are the result of unstable isotopes breaking down, this does not happen in a mobile phone. Gamma radiation is a form of EM radiation but has much, much higher energies than anything put out by a mobile phone.

[Nexus S General] unknownkwita:
will the new API's in the 2.3.3 update make this all easier? i assume because it now supports read and write to some of the mifare cards it wouldnt be that hard to alter them to work with mifrae 1k or mifare desfire
[Nexus S General] kenvan19:
Its my understanding that adding the ability to write (up until now we were software limited to reading) means that hopefully the ability to emulate such cards will be easier.

Hey guys just wanted 2 start out by teling you that I am using dk28 and the newest viper rom. My phone had been working just fine until the other night. Then all of a sudden every time the screen times out the phone will power off. In order for it to power back on I have 2 pull the battery. The weird thing about this though is if the charger is plugged in it will not turn off.

I have already tried reinstalling the rom after a full wipe of the phone. I have also tried a different rom. Should I flash back 2 stock and see if this continues? If so can anyone provide a a link for the files needed in odin to do so.. thanks in advance!
