[Q] Can Xperia Smart Tags be used as regular NFC tags? - NFC Hacking

Are these tags re-writable? Are they big enough to carry complex tasks from NFC Task Launcher? Might be able to get a discount on a purchase... really like the epoxy casing.

Yes and not really. They are Ultralight based, so only 48 bytes of usable space. They will work for a few simple actions, but anything that needs to store text (configuring a wifi network, opening an app) will likely be too large.

Thank you for the info. Looks like I might be going with the tagstand package.

Tetrax Magnet Mount for Galaxy Nexus

Has anybody tried the tetrax mounts yet with their galaxy nexus? Before I purchase one I'm curious of two things.
1. How well does the the magnet stick to the battery door since the battery cover is textured? I have an extra cover that I'll use simply for this.
2. Does the magnet interfere with the NFC and/or screen at all?
In case your not sure what I'm referring to:
http://store.tetrax.us/xway-line/fixway
I have used this on other phones, including my G2, MyTouch 3G and G1 and it worked very well on all those phones. However, due to the textured back on the Galaxy Nexus, the metal button that stick to the battery door does not stay on. I have tried replacing the double sided tape with stronger automotive 3M tape, but that doesn't work either. It'll stay on for a little while and come back off. The only solution would be to find a battery door that is smooth.
I can't answer if it interferes with NFC or the screen, but it shouldn’t. If anything, it might interfere with the magnet on the compass, but that has not been the case with my other phones.

Thanks,
So you've actually tried it on the GNex and it don't stick very well? Did you by chance try holding it on there for several hours with a strong clamp or anything? I really want one of these but worried it's a waste of money with this phone
I have actually tried it, but not with a clamp. Just following the regular directions. On my other phones, it created a very strong bond and it takes a lot of effort to remove. With the Nexus, it stays on the first couple of times you mount it, but that's about it. It's not an issue with the weight, as the G2 feels twice as heavy as the Nexus, especially with an extra capacity battery. It's the texture on the battery door. It almost feels like it has a Teflon coating.

Would you mind holding up one of the magnets to the battery door and test out the NFC to see if it interferes with it (if you have the ability to). This is my main question as I could always put the magnet on a case I guess.
Thanks!
I don't have another NFC device to try it right now, but my brother has the Nexus S and I can try it when I see him later tonight. The magnet doesn't go on the battery door though. What you stick on the battery door is just a piece of metal. The actual magnet is on the device that you mount to your dash or vent, so unless you plan on using NFC while it's on your dash, it should not interfere.
Plus, NFC uses low power radio frequency to transfer information (similar to Bluetooth). It does not use magnets. The only thing in the phone that could be affected would be the compass, as it finds your relation to magnetic North. Even then, I'm sure the compass works through software and is not an actual magnet, as it has never affected GPS. As a matter of fact, I have 2 Tetrax products, the one that mounts to the dash, which I have in my car, and the one that you attach to the vent for when I use a rental on trips for the sole purpose of Navigation. As you can imagine, I was very disappointed when I could not get the metal button to stick. I might have to try it with a case also.

Awesome so yea I don't think it'll interfere because I was thinking the part you stick to the back of the phone is magnetic, but if your saying it's not all should be well. Either way I went ahead and ordered it yesterday anyway so I'll figure out a way to get it to stick to either the door or a case. Thanks for your insight!
Nope, it's just a metal button. It actually comes with 4 or 5 different ones of all sizes and styles.
I have this installed on my nexus, I put the mount on my dash and the NFC sticker on my knob for the ac that get covered up. Everytime I put my phone on the mount, the nfc changes it to car mode, volume up, full brightness and launches sirius xm radio...works very well, sometimes I have to move it a bit to get to read the nfc, but thats only cause i have the nfc a little too far at the bottom of the phone and it mounts at a slight angle, not due to any interference at all. I have NFC chips all around and never have problems reading them at all, probably a good idea not to mount the metal chip right in the middle of the battery area, just in case. I also used a clamp to hold it on for about 3 or 4 hours and has had little trouble sticking to the texture.
I have had a few incidents if I pull off the phone, rather than slide it off the backing will actually unclip a single clip.
@ejkeebler what do you mean by NFC stickers all around? Did you make stickers to automatically change your settings on your phone? That's brilliant! How did you do it?
I might also have to try a clamp. I don't really want to put a case on my phone.

I also have NFC stickers everywhere. have them when I walk in the front door of my house, one in my office at work, one in each vehicle, one in my wallet LOL. They are awesome. Set them to change settings or do tasker tasks and you can rewrite over them if you ever want to change anything. One of the best phone features I've ever used. That's why i was concerned about the magnets interfering with the NFC!

www.tagstand.com to purchase the tags. Tell him DCoy82 sent you! The 30mm ultralight c circle NDEF formatted seem to be the only ones I've bought that work with the nexus so far.
Once you get them you can download program called NFC Task Launcher off the market to program them.

That is so awesome. This is my first phone with NFC so I'm barely starting to learn all the cool things that you can do with it. I tried Android Beam for the first time with my brother on Tuesday and it works great, though I wish you could beam other things such as pictures. By the way, the metal button does not interfere with NFC. I will let them know that you recommended me. Thank you!
If your interested in NFC, here's a few spots that got me started

and the tags I bought were from here:
http://tagsfordroid.com/tags/Home.html
I got them cause i liked the having the android on them, i think they are a tiny bit less expensive elsewhere, and these are a little thicker than I'd like (like a puffy sticker, about the same thickness of a penny) but you can get many in other places.
by itself i'm not sure nfc task launcher does it for me, but in combination with tasker, it's ridiculous how much can be done....would still love to see what others have come up with.
I love those stickers with the Android! Thanks for the links. I will need to read up on it more. I am definitely interested. This is a lot more exciting stuff then what Google showed off at the I/O last year!
Thats a good idea. Being in IT, we have dead Hard Drives laying around that have awesome magnets in them. They're real slim. I bet I could superglue one to my nexus's battery cover for under the TPU case that would hold. They're thin so it might not screw with the case (but it might).

Yeah, it looks like it's $8 for 2. I just picked up 5 over at tagstand.com for the same price and found 10 for $13 over at http://buynfcstickers.com.
Hopefully you guys are all having good experience with the guy at tag stand. His customer service was great for me and I'll definatley be going back there in the future.
Oh and by the way, I got my new tetrax magnet set in today and not having any issues with the magnet at allowing necessary nor with the metal part sticking to the stock battery door. Only real issue so far is you have to slide it off just right or the battery door just pops off the nexus lol. Highly recommend though!

Duplicate nfc tag and use phone instead?

My college campus gives us bulky "sticker" things (about the width of a refrigerator magnet, with a sticky side so we can put it on something) that we can use to open the dorm doors and I think store cash for the cafeteria. Sounds like an NFC tag to me.
Would it be possible to copy the data onto my Nexus S and use the phone as my nfc card? (rather than keeping the sticker on my phone like I see most people doing)
I'm new to this phone and I'm not sure about the limitations with it's NFC capabilities.
EDIT: It's definitely an NFC tag (Phone makes a notification noise when I touch it to the back of the device.

[Q] NFC

Hey guys. Can someone direct me to the best place to buy NFC tags? I want ones that can hold the most data for the lowest price, and I would like them to also be a little sturdy, unlike some of the sticker NFC tags. Also, what is the best application to program these? Make sure these all work with the Galaxy Nexus (LTE). Thanks
I got mine from here: http://tagsfordroid.com
They are great. The keychain is very handy for my car setup.
Sent from my Nexus 7 using xda premium
For some reason, I bought my tagsfordroid NFC tags from Amazon instead of directly from them... both were the same price, both had free shipping. At any rate, the keychain alone was worth the price of the entire package. I have mine set as an "escape" function that someone else here posted. Basically, I keep the keychain in my pocket, and if I wave my phone over my pocket, it will trigger the tag, send a text message to the website ifttt.com, which will trigger a phone call to my phone that says "You need to come home now, it's an emergency, it's bad!"
So if I am ever in need of an escape, like a bad date, I have an escape, lol!
hhaha thats such a good idea

Is there a single NFC tag which changes the content by physical key press?

Hi,
I am not sure whether to post this here, but I take a leap and try it as you might have seen more tags than I did. Please bear with me....
A year ago I came by a local store and I saw NFC tags (mostly the sticker type) on display. I knew my next phone would have NFC so I tried to remember. But one NFC gadget - I got only a glimpse - impressed me:
An NFC pen! Wow, I said to myself, that I want to have. In my mind I saw huge possibilities that the pen would offer: every press on the pen, that inside tube, usually with advertisments, would turn one step. Not to reveal the next ad but to activate the next NFC tag, from my experience (with pens!) I guessed it must be at least 4, maybe 6 tags to cycle through.
Imagine... sitting in a lesson or lecture or meeting or whatever, holding your pen, pressing it a few times, holding it ontop of your Phone - especially while face-down - and silently and unnoticable trigger up to 6 different events... all in one pen, all in one hand.
Guess what, I came by today, very eager to buy and saw that NFC pen. It was a pen. WITH an NFC tag. A single one. What's that good for? If my tooth brush had an nfc tag, it would be of more use (keeping track) - at least to me.
So why the heck bother you with my unmature tech ideas? Did anyone stumble upon any device with a tag/gadget that would support switching tags by keypress? i couldn't find any hint.
Would it be possible with a designated hardware button? My guess is yes, but maybe not in a pen but in those "dogtags"/keyring ones.
If I look at those transparent sticker tags, solve it by using the same antenna and dis/connect the actual logic part. Maybe a little more resistence and noise on the wire switching part would be tolerable.
Or the chip itself could be given a multi personality either the NFC way (speak: is there any technique defined in the nfc specs) or by a contact which is measuring increasing electrical resistance.
Those all are WILD GUESSES. (i got shaky hands, soldering so small structures is not so... pleasant to me, so I won't give it a try)
My idea cannot be so unique, so it must be either technological impossible or economically improbable (say: to expensive to build and sell, not enough sales expected.)
Again, why bothering you? Because here might be so much Expertisé and experience that might yield a hint or two. And, maybe my expectation of a NFC toothbrush... Ahm pen might have amused you.
Nice to hear from you!
(PS: expensive Oral-B electrical tooth brushes do come with .... what? BLUETOOTH!)
Have a look at 'Air Button' and 'Dimple'.

keyboard cover - can it be flipped over?

The new S4 is marketed as to use with a keyboard, preferably the original samsung keyboard cover. In multiple reviews I've read you can use this cover in only one position. What I would like to know is if you can flip the keyboard completely over (360 degrees) as I would do intuitively when using it as a drawing block using the S Pen.
Wondering that too, I've pre-ordered so will get the keyboard cover free a few weeks after I get the device, so potentially it'll be unprotected during that time. I'll probably buy a case from Amazon (seen one for around £6) to see me through.
From what I saw in store, yes the keyboard can flip over behind the device.
Though I did find this interesting on the Tab S3 the little 1/3 flap behind the tablet secured to the back side of the device automatically, pretty well to hold it in place if you flipped the keyboard over behind the screen. The S4 did not, and there was a little extra slop in the case because of this. Course it might be the security device holding it down but its just something I noticed.
Well, yes and no. It can but backwards. It would have been nice if it was able to fold back with the tablet's back against the keyboard but it actually flips over so that the keys are at the bottom and the tablet is at the top. I'm unsure if this does damage to the keys but its not optimal.
Silly question but...
why not just use the otg cable, plug in your logitech module, and use your logitech keyboard and mouse? For the rare times I need a keyboard, that's what I do. Then the tablet is still easily used as you always would, flip, landscape, etc.
just a thought.

That is a silly question because many folks will use this as a traditional portable tablet as well as an occassional desktop machine. When you are out and about with your expensive tablet, you need a case to protect it from accidents, but this case also needs to be convenient. Leather wallet / folio cases are ideal for this, but (most) obviously don't feature a keyboard. Given how slippery this tablet is, with its all glass rear, I'm guessing that accidents may be relatively frequent!
So the OPs original question is pefectly valid. What is the likely durability of the keyboard when folded right over and sat on the users lap, for example, playing Pokemon on a bus? Perhaps, maybe, the keyboard case is an expensive gimmick and a standard leather wallet case would be a much better option (if such a thing actually exists yet)? The real leather case on my Galaxy NotePro 12.2 has served me extremely well over the years.

Who said the OP question wasn't valid? Who said not to use a case?
I'm merely suggesting an alternative for those of us who don't play "Pokemon on a bus", for example.

Personally, I never play Pokemon, however, my daughter does on her commute to work... and the Tab S4 is her tablet Cables and peripherals are totally impractical in this particular usage case. Everyone has different requirements. Anyway, her "free" keyboard case has just been delivered today, so I'll check it out tonight.

You are welcome.
However, this is an interesting point for discussion, as to how folk plan to make use of their new investment. From what I can work out from my daughter, at home it will be docked into a Cable Matters USB-C hub and used to stream movies over an Ethernet LAN connection, to her HDMI TV, amongst numerous other things. At work, she will use it as a desktop with the keyboard case and a bluetooth mouse. I've already described her commute.
If it were mine, I'd be using it as a passenger navigation device, along with AlpineQuest and a full set of OSGB maps, which is what I currently do with my aging NotePro.
Now that I've received the keyboard case I can confirm that the case can be flipped in such a way that the keyboard faces up, into the rear of the case when using as a traditional tablet. In this mode, the footprint of the tablet extends along a long edge by 38mm, which is due to the way the "fold" works.
Alternatively, it can be flipped with the keyboard facing down, which only extends the footprint by 10mm along the same edge.
First impressions are that it adds a fair bit of weight to the tablet, mainly due to good build quality. The case is pretty solid, but not padded, so it may not be great at absorbing shocks, say from a drop! The keyboard is compact, but has a reasonable feel. Note, that the pen is essential for using the keyboard with DeX as there is no trackpad.
Is it worth the RRP? Err, no, however, as a pre-order "freebe", I've got no grounds to complain.
