Hello.
I recently accidentally put my sw3 under my phone and it opened wear app by scanning watch via NFC. It would be very nice if I could program that NFC anyway I want. But NFC Tools says it's read-only... I managed to add that NFC as trusted device in SmartLock and it can unlock my phone now, but after that it also opens wear app... Because it's a watch, not a tag maybe there's the way to reprogram it?
Thanks

Hello!
Currently I am writing my Master's thesis. For this I am supposed to use the NFC function of the Samsung Galaxy Nexus to turn on/off certain devices such as a flat iron or a stove.
My idea was to use an RFID access control as the ones used to open laboratory doors or the like and attach its relais to the devices' power switch. One could hold the phone next to the device to turn it on/off if permission is granted.
However, most of the access controls I've found are only for 125kHz. As far as I know NFC uses the ISO/IEC 14443 standard which communicates with 13.56MHz. What confuses me though is that some sources say it works with the NXP Mifare Ultralight C chipset but not with the Mifare Classic 1K. Can anyone explain why that is? But even more important to me is: has anyone a good suggestion on the access control I should use in my case?
I'd be happy about any reply!

Just an Idea and hear me out...
As far as I remember most access control (Which I used to use about 7 years ago when I was working for a plant as a part time IT) is nothing but the right string of 101011010, a few bits of data stored on a magnetic strip on a card, or the older NFC chips that could changed, but only store 1 "Tag" at a time.
With most NFC chips in our newer smart phones we have the control to change the information that is broadcast by our NFC on the fly, and even better it is a two way transmission (Which is what makes Google wallet possible.)
If you were going to attempt to make a stove or other device turn off and on with an NFC chip, you would be better off not looking for an access control solution. I would try using another computer. Something that can be programmed with an NFC chip to receive a certain bit of code that says "Turn on front right burner at 50%" and then reply with a conformation saying when the action is complete.
A small Linux box, with an NFC and a single program, and Knowledge of external interfacing.
A smart phone with preset tags that can be chosen to do different actions, and wait for a confirmation.
I think that would be something new and applicable to the real world.
Hope this give you some ideas
After I get done with my current project I am going to make an android app that lets you create an NFC tag and write it to any tag, so people can program there router, stick an NFC Sticker to the side of your router any anyone with an NFC chip will have instant access to there network by touching the router.
Switching on a device using NFC
I have a similar requirement; i.e. to activate a device using NFC from a phone or smart tag. My question is whether the induction power of the NFC from the phone is sufficient to turn on a device that is an off state prior to this.

Yes , but such tag isn’t available online, such tag can be only order from specialized manufacturer, we are making some stuff will turn on & off bluetooth device, and it work like a charm. Need soldering to bypass the existing on/off button.
hope that help

Probably not, you will need something (small chip) that just listens for the right tag and handles it for you.

Hi guys,
There is a question to Smartwatch owners.
Does anyone tried to use NFC tag in the watch to open a door or gain access on other RFID device?
I'm considering to buy a watch and the main reason to do it is abillity to use it at work, where I have to go through many doors where I use my Nexus 5 or just simple keyfob with Mifare chip.
I don't really understand, why companys like Sony, LG or Samsung cannot see this, that is a game changing feature .... There is until now, just one company which thinking about that.. but theirs watch isn't smart : http://www.winwatchtrade.com/the-key-nfc-mifare/
Be something that would be very cool, would have to see if NFC Tagwrier can be sideloaded..
Even if it worked on the watch, it may not create workable NFC tags,
Hope somebody tries this. I did try but was not able to read any NFC tags

Tried and worked with an HID iClass R10 Card Reader. Problem is that the watch's nfc sends the same info from all Sony SW3's, so not secure.
Hey Everyone!
I just bought a Moto 360 even though I have an iPhone. Through the use of a trusty old Xperia U I managed to do the first configuration and update to the latest O.S. on the watch, adding the Wi-Fi standalone connectivity.
The use I want to do of the device is the following:
Occasionaly, through the Android phone, add watch faces
Siply use the watch standalone for Steps, Heart Rate, and notifications maybe with Aerlink
At this point I would like to set the watch to connect to my home wifi network, and simply upload the fitness data to Google fit in the cloud, without ever using my old android phone (except for new watch faces or changing configuration or updates). Can anyone help me out in achieving this??
Thanks to all!!
I recently bought this device to help me track my activity, and analyse my sleep. Problem is this device can only be paired within the app, I can't pair it with regular Bluetooth process on the phone. Does anybody know a way to force pairing with the device code or a root app, that can manage devices more efficiently.
Why ? Because I want other apps to use the wrist band's data.
Link to the app on Amazon :http://www.amazon.fr/gp/aw/d/B00VWC...+bluetooth&dpPl=1&dpID=41K+TlFIixL&ref=plSrch
Is it possible to clone/copy a nfc tag to my phone so that i can use my phone as NFC tag.
Like scanning a Nintendo Amiibo to my phone, and using my phone as amiibo.
Or scanning a Amiibo to my phone and copy this to a clean new NFC tag.
Thanks
