NFC Cards -- What sizes to get?

I'm probably going to get a starter pack with 48, 144 and 1k byte sizes but I was wondering what sizes others are using. I'll probably be posting back in a week or so to report how much data my various tags use.
I'm really excited about how powerful NFC could be for making phones easier to use. My only concern is whether or not 48 and 144 byes is enough for some of the things I want to do.
I'm interesting in turning off/on WiFi and Bluetooth when entering/leaving my house. Same with for my car dock but with GPS/Bluetooth. I'll probably put one in my wallet to turn off GPS/Bluetooth/WiFi (as a simpler way to turn off battery wasting signals). I've no doubt that I'll look into other things such as web/app shortcuts and adding contact information. I"m just not sure how much data each tag would take.

Yeah where can I get 5 or more?
I need to be able to write/read. Variety of sizes is good too. Located in Canada.
I'll put one in my locker haha. Disable wifi and go to vibrate and silence all apps with a tap. Then I'll use my "Enable" card to tap for full volume everything and then enable ringer and wifi.

Agreed I'm planning on picking one up and would love to set up NFC tags for everywhere i regularly go

Mine should arrive tomorrow. I haven't decided what do with mine. I use llama for location based changes. I'll turn one into a contact to keep in my wallet for business card data exchange. That leaves 9 blanks. Hmmmm....

144 bytes is probably enough for most things you'd want to do.

Looks like 144 will be enough for you.

Agreed. The only thing I've used the larger tags for was storing a vCard. And if you want to make your scripts even sorter, you can always use NFC to launch a Tasker task which can be as long and complex as you would like.

If you take a look at my picture attached to my earlier post you'll see a list of activities (wifi on, bluetooth on, etc). Those are the things that the phone will do when you hold it near that specific tag. So if I put that tag just inside my door and scan it when I walk into the house the phone would turn on my wifi and bluetooth, check me in on latitude and turn my volume all the way up. You can also have a tag launch a Tasker task.

I've got a few 112byte tags from some ex-library books.
Ive got one as in leave/enter the house to turn off/on wifi. I Also have one on my nightstand to enable silent mode
112b is fine for what I need which is ideal

omg that is the coolest thing ever! I gotta get me some of those. Thanks for the explanation.

Is there Cards & Stickers? or is it just different names on the same product?
Could someone point me to a card/sticker that works with our phones?
I have google it a bit but there seems to be many different types.
Cheers!

Idk about cards but that is one of my stickers next to a quarter for comparison.

I think I am going to play around with this. already LOVE Google Wallet. I have three quick questions though.
1. Is it recommend/necessary to purchase pre-formatted tags to use with the Verizon LTE Galaxy Nexus? I have just switched to Gummy ROM based on 4.0.3 (I know need to update my signature). From what I have read 4.0.3 will support formatting, but is it just easier to purchase pre-formatted tags? Better question: Is there a down side to buying pre-formatted tags?
2. Which app would you recommend to program the tags with?
3. Anyone know a reputable supplier of NFC tags for someone in the U.S.?
I appreciate any advice.

1. The tags I've bought are off of eBay some china seller. They are pre-formatted as NDEF no downside that I can see as they work perfectly
2. I use NFC Task Launcher from the market it works great. Also the NXP apps are good.
3. Everyone seems to say that tag stand.com are good I've never used them as I'm from the UK

1. 4.0.2 and earlier had a bug where they couldn't format tags. Apparently that has been fixed in 4.0.3. I got mine preformatted. the place did it for free.
2. I used NFC task launcher. The free full version posted by the developer is in a thread around here somewhere. It is also on the market for a couple of bucks.
3. I got mine from these guys located in Florida. They shipped fast and used Google Checkout so I didn't have to give them my cc number.

Just ordered some from tagstand.com
I didn't get pre formatted, but they were cheap... I will update when I get them

SIM cards only come in GSM phones, so this is not possible. It is possible to flash it to Verizon though, since VZW uses CDMA

you may have to be the best soldering expert ever to pull that off, and even then, haha. try it though, you could make a gsm/cdma hybrid device, thatd be cool!

Actually I wouldn't do that.... That stuff would get everywhere, and it conducts electricity too..... You could risk shorting your whole phone and frying it. However, if you made a like rubber ring or something what would keep it it place better, it would most likely increase the heat transfer. But keep in mind these phones, just like laptops, were designed to have higher heat tolerances.

[REQ] NFC chipset ID and maybe the ICS driver file links

I am requesting the resource for completing the piece of puzzles of NFC support I am tossing on the Samsung Galaxy Captivate Glide. I thought it wouldn't be possible but now I'll have to see - I am not willing to sacrifice my phone (my daily driver - but I don't mind bricking it because I am capable of recovering it). If anyone have dead SGH-I927 or otherwise, I would like to have a few picture of motherboard and the macro shot of chips so I can look for the datasheet, thus finding the correct driver for it.
P. S. Please take a real good macro shots of the chips because I would like to know the model numbers on it so I can find the datasheet (I am interested in trying to add support for the NFC). You can try using LED flash if that helps.
Plus, Moderators - you can move it to Captivate Glide General if needs to be - Tapatalk lacks the feature of being able to pull the post and move to different thread.
Sent from my SGH-I927 using xda app-developers app

Maybe the guy who opened his glide could help you: http://forum.xda-developers.com/showthread.php?t=1884472

Wait, are you trying to add a NFC chip to the phone? Or are you under the impression that the Glide has one installed? Because I think it's been pretty clearly worked out that there isn't a NFC chip on the Glide.

Just take the back cover off, it's 7 screws and the motherboard is right there, you don't even have to take aything else off.

I still think that square strip on the back of the battery cover has something to do with it but probaly not
Sent from my SGH-I927 using xda app-developers app

There are no contacts between the sticker and the body of the phone, so I doubt it's a NFC chip.
On top of that, nowhere is the NFC chip documented in the FCC test for the Captivate Glide. Were there one on the phone, Samsung would have had to report it to the FCC and it would have been noted in the reports.

Well, I do think it have NFC chipset since I saved the snaphot of Melvatron's phone - I opened mine before (dented camera cover so had to fix it).
Why? There are more than two antenna traces - I see four.
Plus, AT&T can do what they want with it, even going as far as desoldering the NFC chip.

Can we get this post stickied somewhere. I feel like this subject comes up unnecessarily often.

Hmmm... I wonder why GSMArena and many other cell phone review websites claimed that it have NFC. I would like to investigate for myself, maybe even try probing the IO for any signs of hidden hardwares (AT&T have been proven to be hiding things they don't want us to use, anyways).

Where are the four? I see two.
I've taken the Captivate apart before as well and I can tell you that I didn't see a single trace of a NFC chip on the board itself. The most common NFC chip manufacturer is NXP. NXP chips look like this:

Samsung's in house NFC chips look like this:
(The other model is SENHRN2 and looks similar.)
None of these chips are on the Captivate Glide. (If you don't believe me, I can try to provide pictures of the entire motherboard, although I'd need to find my camera charger.)
Also, there's still that FCC thing that I mentioned... If it was there, it would be documented.

I'd imagine GSMArena made a mistake and other websites copied their data with the same mistake in it. (Or vice versa.)
AT&T would only be able to hide it at the software level. If the physical chip isn't there, there isn't NFC.

Ah... Ok. I guess so. I am not saying I don't believe you - sometimes I need to be sure, hence the analysis on both software and hardware.

GPS is still screwed on ICS? because it sucks on the leak.
Sent from my SGH-I927 using xda premium

Ok. You can try the workaround: in sirfgps.conf, edit the line "LNA_ENABLE" from 1 to 0, and optionally switch "FREQUENCY_AIDING" from 0 to 1, and copy gps.conf from an Android that's known to lock immediately (I also posted gps.conf zip on my GPS workaround thread). It should be able to lock at least 5 minutes maximum from cold start.
The reason being, Samsung didn't really pay attention to the LNA circuit board placement, and/or the antenna in where the RF from CPU VRM (Voltage Regulator Module) is. There's more than one way to mess up a GPS electronics.
EDIT: If you have the information for the GPS band assigned for your country, you can try editing gps.conf directly after making a backup copy of this file - you would have good chance of finding out what band around here in XDA.

Ever since I got the pictures from three2four of the SGH-I927 motherboard, I could now agree that the myth of having NFC is busted but I want to check under the SIM card then I'm good. (Thanks, three2four! I wasn't willing to open my own phone for any reason other than performing the repair on it.)
In the picture, all I see is audio DSP, DDR-II chip (soldered atop the CPU), GSM broadband modem chipset and GPS transponder processors and few support chipsets, and that's it.
EDIT: I am actually bummed out as I knew how useful it is, especially with the online purchase or running your own personal business while dealing with the credit card (Japanese Visa cards are a good example as they have been using the NFC for few years). Think of lot of uses for the NFC... Too bad it doesn't have that as I checked the pic.
Sent from my SGH-I927 using xda app-developers app

The picture of three2four's Captivate Glide motherboard didn't show the area where the SIM card' boards removed, so the curiousity have gotten the best of me, I decided to carefully disassemble my phone, and removed the SIM card board (It was glued onto the RF shield so I had to snap it off) and take the picture of the RF generator - even though I don't think it have NFC but who know at THIS point?
I already reassembled it back together so I can be able to post onto this thread.

Which NFC tags?

I am actually using free NFC tags I received from the app NFC Task Launcher app. All you had to do was tweet that you were using the app, then submit your information and they mailed you 2 free NFC tags. I was lucky, I actually submitted my info twice because I reloaded the page, so I ended up getting 2 free pairs of NFC tags.

It depends on what tags you're talking about that work with the S3. If you're talking about Samsung Tectiles which are basically rebranded MIFARE Classic 1k, then no they will not work with the GS4.
If you're talking about NFC Forum type 1-4 (the most popular being type 2 aka NTAG203), then yes they will work with both S3 and S4. There is nothing special you have to do such as "reprogram the tags".
Some more related info here under NFC Compatibility section.

Not sure if it's the frequencies or packets, but on a higher level the S3 uses an NFC controller by NXP, which is compatible with MIFARE Classic 1k/Samsung Tectiles. The S4 uses an NFC controller by Broadcom which is not.
Samsung is coming out with Tectile 2 tags which should be NFC Forum type 1-4 if I had to guess.

Any NFC forum type tag would work (aka "universal nfc tags").
They're available on eBay.

I've had no problems using NFC tags, but if you are using a custom ROM, check that it supports NFC. I'm using ARHD 12.1 without any NFC issues.

I read that some older style NFC tags don't work with newer phones like the HTC One, something about being incompatible with the older style Mifare 1k tags. Ntag203 tags are definitely compatible, so I would suggest searching those up on Amazon. I personally like the ones offered by Tagstand: http://www.amazon.com/dp/B00ANY1ZTS/ref=cm_sw_r_an_am_ap_am_us?ie=UTF8
The designs are minimal and look nice. They're also pretty much as thin as a sticker, so they're low-profile. But apparently they're pretty much destroyed if you try to peel them off.

GPS receiver on Exynos model

Which Broadcom GPS receiver will be used on S9x ?
Is it the same BCM4774 like on older models, or the new dual-frequency L1/L5 BCM4775x ?

I still can't find the exact spec, but what they're showing doesn't look promising. the GPS "spec" from the marketing gibberish is exactly the same as that from the S8:

The marketing people never (can) provide any usable technical information.
Even google people give you a pretty useless device table at https://developer.android.com/guide/topics/sensors/gnss.html
although they certainly know better: all phones with 'yes' in "Accumulated delta range" use BCM4774, and support Galileo (excluding Nexus 9 in the last row, which uses special firmware and has an older Broadcom chipset).
I hope somebody will do a hardware teardown, or will enable debugging log options in gpsconfig.xml on a rooted S9x
IMHO, the chances for BCM4775x are pretty slim, but let's hope for the better.

OK, just pre-ordered . Is there a way other than rooting I (or teardown!) that I can use to determine the GPS chip? If it's not the BCM4775 I'll probably just turn around and sell it prior to activation and don't want to mess it up too much

Is that dual frequency thing really that important? What's about it that makes it so important?

Poor man's surveying equipment.
I have some rough land surveying to do (and potentially re-do over several iterations marking different boundaries) and the current ~10m range of accuracy doesn't cut it, while the ~10cm on the dual frequency chip would suffice. No, that is not my sole reason to consider an upgrade (as well it shouldn't be), but factored with everything else it pushes it over the edge. If it doesn't, I'll just wait until my S7 totally poops the bed in another year or so.

The only non-invasive way is to install this APK
https://github.com/google/gps-measurement-tools/releases/tag/2.0.0.1
and check the logs for L5 pseudoranges et al.
This approach is not that reliable as teardown | rooting, and can provide a false negative result.

It's dual carrier. 4755
Extracted this from S9 firmware
Edit: it seems like it's disabled tho. No CM accuracy

Wow. And the a*holes keep quiet about it, damn marketing people
Maybe one needs to upload some firmware patch for L5/E5 to work properly.
Where can i look at the gpsd binary ?

On the rooted phone you can edit gps.xml and enable the dual-frequency operation. I have written about it in Huawei Mate 9 GPS thread.

Great, thanks!! I guess I shouldn't get too pedantic, but Broadcom is calling this the BCM47755...should we just concede that this chip shows up as 4755 in firmware?
I can't decipher where in that xml it's saying it's disabled, but does it stand to reason that enabling this could come from a software update from samsung and/or verizon? i.e. I should keep the S9 once it arrives and they hope for the best??
Thanks!!!

This is the Broadcom enum for possible multifrequency modes:
Code:
GL_MULTI_CARR_RF_MODE_UNKNOWN
GL_MULTI_CARR_RF_MODE_L1
GL_MULTI_CARR_RF_MODE_L1_L5
GL_MULTI_CARR_RF_MODE_L1_LP
GL_MULTI_CARR_RF_MODE_L1_L5_LP
GL_MULTI_CARR_RF_MODE_L1_L2_L5
GL_MULTI_CARR_RF_MODE_L1_NN
L1L5
L1LP
L1L5LP
L1L2L5
L1NN
L1_EXT_ON
L5_EXT_ON
It is also interesting that they still stick to the 'rtistatus3.dat' for RTIconfig, which does not support Galileo. You can use rtistatus4.dat available from Broadcom site to fix that.

It's on the GPS.xml file. I've deleted the whole system.img tho. So I can't open it anymore

If you already have the phone, please install this APK and tell me if the 'Galileo Navigation Messages' are being logged. They do not work on S8 and Huawei phones (all using Broadcom BCM4774).

I have a pre-order. Supposedly ships on the 16th, so I'll have it a day or two after that and I'll give this a whirl.

Thanks. Finally we have a real innovation in the smartphones, and not just a plastic cover color change ! +1 for Samsung.

Not to be offense, but how could tell the new S9 would be using BCM4775X family?
According to Broadcom webpage, are there any chances that BCM4755 would be some kind of OEM product between BCM4752 & BCM4774? Are there any apps that can log / indicate that uses L5 channel? Thanks.

Welp, this is discouraging:

Samsung S9 does not have Broadcom BCM47755. This information is 100% reliable. Only in S10 will they give the BCM47755 chip.

I will wait for the first real hardware teardown.
