[Q] Is there a way to test NFC feature?

It has been over 5 months since I purchased Nexus S but I've yet to found a person that owns Nexus S nor ran into a place that uses NFC technology.
I was wondering if there is a way to test NFC.. maybe like a purchase a chip or sticker (if there is, could anyone help link to a NFC that is compatible with Nexus S)?
Are these re-writeable too? And what are somethings I can do with it? Like turn on/off the light?
Thanks!

Well Portland, OR is a "test market" and I'll be there tomorrow, so I'll see what I find.
My guess is nothing more than NFC stickers on businesses similar to codes you can simply scan with your camera.
I mean you can hold your credit card (if it's a blink capable card on the back) and it will beep at you, but NFC is far in it's infancy to be useful.

This app can do stuff when comes in contact with certain NFC chips and can also rewrite them. At that thread you can find suggestions about which chips works fine with our phones and where to buy them from.

if your in the uk try smartcardfocus, i have used them for stickers and postage was very quick.

I'm in U.S.
I like these (http://www.tagstand.com/collections/mifare-classic-stickers/products/nfc_circle_25mm_l) but these are sold out at the moment.
Thanks for the app link. Now I have better understanding of what it can do!

Found something new about the S4 just now!!

So like many others I'm sure I've been obsessing about the new S4. I pre-ordered mine yesterday and have been doing more research ever since.
While getting "lost" on the internet usually leads me to cats instead I found out about Mobeam.
It's basically a cool new feature that allows the S4 to project bursts of light from a LED or maybe IR which a POS system or traditional barcode scanner can read.
What does this mean? It means we should be able to scan coupons loyalty cards, gift cards etc and then when at the store have the cashier just scan the top of our phone to accept the barcode.
I'm probably getting excited of something I'll never use however I like surprises...

I wonder if that will help bridge the gap with physical retailers and online coupons. I use my phone a LOT when shopping because I can always find a deal and save some money, but it can be frustrating when you get a coupon and then the cashier has to verify that it's "legit". It would be simpler if all online coupons just came with simple bar codes that can easily be scanned and matched up in the computer. Some coupons do this already, but really every one of them should.

I absolutely think it could bridge the gap, but this depends on the right environment.
1. Mobeam has patented this technology, as thus it's going to need to be affordable to license it to the masses. (Interestingly enough in Mobeams' FAQ section under investors, it lists Samsung Ventures among several others)
2. The companies that make the products we buy everyday will need to jump on board and work with retail stores and app devs to get these coupons seamlessly integrated to mobile phones.
The most important thing of all this is $$$. Basically every store already has the barcode system in place, so not having to upgrade all of those systems to use rfid or nfc (another way mobile coupons can be used) will be a huge cost savings.

Was confused for a second so I went and looked up a video on on Mobeam, and wow, I didn't realize that was the full potential you referred to. That is actually really cool! I heard the HTC One also has an IR blaster, so couldn't it do this as well? Or is Mobeam's technology patent such that 3rd party developers couldn't really copy that feature, and for now it's exclusive to Samsung?

I think it uses the notification LED on the phone. The video shows the scanner scanning the face of the phone which is where the LED is. The IR is on top by the audio jack. That leads me to believe that this could work with most phones.
I'm thinking that their patent would def protect them so as no other company can use this tech with out licensing it from them. What that costs who knows. The most interesting thing about this is that Samsung apparently invested in them, to what degree again who knows. If Samsung invested heavily then maybe they will get to have the tech for a while before the company licenses it to other vendors. It will be interesting to see how this all plays out..

I don't really get it? if you're going to scan your phone, why not just have the barcode appear on the screen like most other things?

The S4 has an IR sensor on the top of the phone as well (separate from the IR blaster on the front). It is used to detect hand gestures. I don't think many other phones have this technology yet.

Go to the site and watch the video...it explains why.

It's probably just as simple as the tech to read a smartphone screen is really expensive. The only other option is RFID and NFC all of these would require serious investments on the behalf of retail stores. This tech allows retail locations to use their existing laser scanners.

Basically MOST scanners in stores (laser scanners I think) can't read a glass screen it just sees reflections. Newer stores with newer/different scanners can read screens like the ones they use at starbucks...but the purpose of this is it can be used anywhere with ANY scanner. Pretty genius actually!

Sure, idea is cool, but given that scanners do a pretty awesome job with barcodes it is kinda redundant (I know, I used to test them on different surfaces at my old job just for fun)

RFID scanning?

Hello,
I have a Galaxy S7 international and rooted Nvidia Shield K1. I lost my wallet I figured out probably somewhere in my house and have looked pretty well and could not find it. I still need to look more but am wondering if any apps make it possible for my S7 to scan for RFID chips that might be in my credit cards? Do I need a scanner to connect to my Android device to do that? It is going to be difficult to find my wallet if it is here as I was in some rooms in the basement where it is really messy.
Is this even possible if the RFID chip is not held up against the scanning tool, or could I detect a chip that is a few feet away?
If not possible..for future it would be interesting if I could put something in my wallet so that I could quickly detect it if it is in the same room.
Thanks

Well, I found my wallet..

Samsung Pay

I have bought Samsung products - phones, tabs, watches - for ages. And I completely understand that Samsung want's to promote Samsung Pay. I do. But I DO NOT want this on my phone or watch!! Forcing me to keep it there is NOT going to make me more willing to use it. It will and has had the opposite effect. This sort of bullying marketing combined with the fact your customer support is slow to non-existent is starting to make me look over other products that respect my wishes more.
Just throwin' that out there.

It's not bully marketing. It's a feature. And for watches, mobile payment is one of the compelling use features. There are few tasks that watches can perform better than phones, mobile payments is one of them. Paying with a watch at a POS terminal is easier, faster and more convenient than pulling out a wallet or phone. Furthermore​, Samsung has the lead in this area because they're the only ones using MST, which works almost everywhere.
You may not be on board, but it is the future.

No argument. But by forcing me to eat up space on my watch and phone it becomes bullying marketing. Let me remove it ans use the space as I choose.

if you don't want want to use it just delete samsung pay app from your devices)
for my opinion this is really great way to pay. don't need to have a card in pocket and it's really safe

Brilliant idea! Except it wont delete. Hence my frusteration.

I'm using samsung pay almost every day on my gear s3. why you don't like it ? it's really save my time

It's a feature of the watch. Advertisement of the watch promoted it. I am just waiting for my bank to get round to support it, making life easier.

I really don't like Samsung Pay and didn't use it before I got this watch. The need to unlock your phone and then use iris detection to unlock Pay is a pain. Android pay is a simple unlock of the device job done. Much slicker. Don't even have to have the app open.
I hate the swipe up card tray thing on the phone too. As for the watch, it asks me to enter a pin everytime. Can this be disabled? If its linked to my device, that should be enough security.

gear s3 does not have fingerprint sensor so pin is just protection from third party users.

yes but if the device is connected to my phone, whats the problem in keeping it unlocked? Its an unnecessary control IMHO. If I lost my contactless card, what control do I have over that until I ring the bank?! At least with my watch, I can use my phone to kill the link.

Mobile payment using a phone is a hassle. S Pay on the Gear S3 is seamless. No need to unlock the screen or enter a pin each time. Just press the top button and tap pay. S Pay on the watch is works completely independent of the phone. The phone doesn't need to be connected to it.
To disable the pin requirement in settings: Security -> Screen Lock -> Payments
The pin will only need to be entered the first time S Pay is used if the watch was removed from your wrist. I typically only need to enter my pin once a day.

RFID read/write on OP7Pro

Wondering if this is possible as a native feature on OP7Pro. Ive seen some information on the feature being native on Oneplus One (not sure if true), and seen info about it being possible with the Proxmark3 RDV4. It is for learning and testing purposes.
Seems like the world of covid has gone quite contactless; from ski passes, payment methods, apartment amenities and so forth. Want to examine and understand how it works, the coding behind it, the security, and the potential to break.
Best wishes,
PP
