There is a mod in the EVO 4g LTE and HTC one x forums that let's you choose when NFC can be read.

Screen on and unlocked,

Screen on and locked, or

Screed off (obviously locked)

I modded the phone to read tags when the screen is on and even if the phone is still locked. Allowing it to read while the screen is off may be a security risk for some.

Anyway,

On my keychain:

Switcher:

WiFi off, Bluetooth on, volume up, brightness up, latitude check in, plays media player.

This is great because it automatically connects to my car Bluetooth headset and the HTC aux stereoclip so music starts playing through my car speakers wirelessly via swipe of the keychain.

Tap again to disable all these and check in again w latitude.

I also have a separate tag in my car low on the dash to enable GPS and open maps so I don't have to fiddle w my phone througg the settings and open the app drawer to open maps. Makes driving that much safer. Also, I don't always use GPS, so having a separate tag for it from my keychain saves battery by using it only when needed.

Trying to set up a tag to enable WiFi tether for root users and stick it to my laptop/pc for quick swiping and enabling. But that has been tricky as you either have to use tasker or a custom activity in NFC task launcher.

Can't think of any others relevant to my interests. I don't see the need in making 38583983 tags. I definitely use the ones in the car tho.

I may order a wristband and think up something creative for it. Assigning a "sync all" activity would rock for it as I keep auto-syncing on my phone off and only sync email and such when I see fit.

Phew.
[NFC Hacking] hollywoodfrodo:
For the two of you who permanent contact?

For example, I have a car dock in my car. My thought was to put the NFC Tag sticker on the back of the dock so when I put my phone in the dock, it would obviously hit the tag and trigger my car settings (wifi off, bluetooth on, etc). Then when I removed the phone from the dock, I'd want it to trigger other settings (bluetooth off, etc).

Since the phone would be constantly against the tag, though, would it be continually triggering switches back and forth? Or would the initial switch trigger upon putting it in the dock, but in order to trigger the 2nd switch upon removal I'd need to move it away from the tag, then tap it back on the tag to initiate another trigger?

Thanks for your help. Trying to fully grasp how the NFC tags work.
[NFC Hacking] krohnjw:
With android there's no indication that a tag has gone out of "range" broadcast to the system. Essentially to get the tag to re-fire you'd need to either move out of range and then back in or turn the screen off (disables NFC) and then back on and unlock the device (restarts NfC and re-reads the tag).
[NFC Hacking] zvieratko:
Two important points

1) NFC doesn't usually work with screen off, so you either need to patched NFC.apk (for example AOKP b40 has this feature) - otherwise, everytime you switch on screen, it would trigger the tag again

2) there really is no way to trigger action on tag removal

I solved this (sort of) by having two tags - one in dock and other one that resets to "default" settings that I swipe after I leave. Not pretty but working...

Or you can set the actions as toggles, so one touch - set for dock mode, and second touch - revert back. But it obviously doesn't work for everything.
[NFC Hacking] Zanith:
Simple solution to that, get an app that detects other hardware features so it can detect when its being moved, ie proximity detection, orientation.

You could also get a fabric nfc tag and sew it into your pocket?
[NFC Hacking] Necro990:
I created a tag that does the following:

->Turns WiFi on

->Waits until I'm connected to my home WiFi connection.

->Sends a WOL packet to my desktop at home

->Wait 20 seconds

->Turn Wifi Off

So when I get home from work I can put my phone down on the tag and my PC will automagically begin booting :D
[NFC Hacking] Disconn3ct:
For the obvious uses, don't forget night mode - turn ringer off (or on, depending) turn off mobile data, connect to home wifi, etc.

If you just want to mess with tags, go to your local tmo or bestbuy store and pick up a pack of the samsung tectiles. They aren't as cheap as you get online ($15 for 5 vs $1-$2 each) but they are decently large and work just fine. Once you run out you know its time to order a bunch, and you'll probably have a better idea which ones you want to order.

As an old-school embedded hacker, does anyone know of a vendor that sells the DESfire E2V tags with a tag dev kit? I've got a bunch of ideas for cool apps, but I need to be able to modify the OS on the tag. (Take a look at the specs, its pretty neat. up to 32k of storage, with security etc, all running on an old Intel embedded CPU from the 80s.) The only ones I've found so far have the firmware distinctly read-only. I suspect it is using the on-chip ROM, which means it would take impossibly delicate surgery to replace. (There is a pin that toggles between booting on-chip and external.) In theory a dev kit would be set to external and come with a jig or other tool to write it, as well as OS binaries for the standard NFC OS..

As a random easy example of stuff you could do, think of a write-only tag that took vcards for a mailing list (or a roll call) but didn't let anyone but the authorized user read them out again. Right now you'd need to put a full embedded computer behind an active NFC module to do that - a lot more expensive and more failure-prone than a custom tag..
[NFC Hacking] mmameli:
The command IF

I think that without the command "IF" and "SWITCH" the use of this tags is too easy and useless.

Are these two commands available?
[NFC Hacking] sysadmn:
I had problems with double-reading when I'd fumble putting the phone in the car dock. It snaps into place the dock, and it would sometimes read when it got close to the dock, then again when it snapped into the cradle.

I put the tag on my sun visor instead. Sit down, touch the phone to the visor, put it in the car dock. Arrive at work, pull the phone from the dock, touch the visor, and go.

Same thing with my at work tag - I put it on the side of my desk so it wouldn't re-trigger if I removed the phone from my work dock to answer it.
[NFC Hacking] hollywoodfrodo:
Anything is possible with Tasker

You can definitely do "IF" commands if you use Tasker along with NFC Tags. Since Tasker doesn't natively support NFC, switch isn't a possibility, but since switch is built into many NFC apps, that's an easy one.
[NFC Hacking] waiters:
I programed my vcard on a tag and put it in my wallet.. Instead of exchanging info if they have an android or blackberry with nfc I just hold my wallet to their phone for a second and it will open the vcard on their phone and ask if they want to save it.

The tag is always in my wallet ready to go.

Surprisingly I've used it more then I thought I would already.. It's kind of fun also and people get a kick out of it.
[NFC Hacking] gremlin007:
I tried the NFC tag programmed by my SGH-I747m with a blackberry phone and it didn't work...it did for you?
[NFC Hacking] krohnjw:
What type of tag was it? BB doesn't support Classic 1K tags.
[NFC Hacking] angelvsqz:
Bluetooth NFC and Speaker ;)

Okay here is what i got. I bought a tango trx for my ipod touch

But the other day i ordered some nfc tags and bought tasker and nfc task launcher.

I wanted to be able to auto connect, open pandora and turn on wifi.

I created a Task on Tasker.

That task toggles Bluetooth.

I then I wrote that task to a nfc card using NFC task Launcher.

Back to tasker.

Set up a profile to activate when "bluetooth on" task is on.

that profile loads pandora, turns wifi on, auto brightness on,media volume to 10 (in my case), screen stay on if on USB or DC , and ringer volume to 7.

Then I created an exit action that goes home if bluetooth is off. that auto closes pandora and stops play back.

okay so here it goes:

place phone on nfc tag,

opens pandora,

bluetooth on,

auto connects to my tango,

and begins play back.

when im done, I place phone on nfc tag again,

closes pandora, turns off bluetooth, goes home.

I hope it helps a little.
[NFC Hacking] Grousso:
I had a tag to my cars window which lead to a tasker task.

This task is a sl4a script with this code:

import android

import time

droid = android.Android()

print "Connecting to arduino..."

# Change the the following line to match your MAC address.

droid.bluetoothConnect('00001101-0000-1000-8000-00805F9B34FB', '00:12:03:27:72:57')

droid.bluetoothWrite('unlock')

time.sleep(3)

Inside the car i had an arduino with bluetooth ('00:12:03:27:72:57') and when takes "unlock" moves a servo and i can unlock my car
[NFC Hacking] gonzlobo:
I bought a bunch of 48 byte key chains from buynfctags.com. If they're programmed via nfc task launcher, I can only fit 2 commands on each. If I use cm10's profiles, I can fill a profile with many (5+ so far) commands.

My question: LTE reception at work is ****ty at best (so my battery drains quickly). How do I disable LTE, but keep 3g?

[NFC Hacking] PantechBurstOwner:
i dont have NFC in my phone but i have a nexus 7, when im at home i dont feel like just turning off my password every time i get home, is there a way to get an NFC tag to instantly unlock your phone/tablet?
[NFC Hacking] sysadmn:
On my nexus, the phone has to be unlocked for NFC to read. Search this forum, there is a hack to get around that.

There is also a thread about using Tasker to turn off your pin when you're in your home wifi. You could probably adapt that to use an NFC tag as a trigger.
[NFC Hacking] Badger2point0:
This... This I like. How exactly did you achieve this, care to go into a bit more detail?
[NFC Hacking] PantechBurstOwner:
Sounds good, ill program it and slap it on my wall next to the couch by the TV so when I get home I can just put my stuff down, unlock it with the NFC tag and use the nexus 7 as a remote

[NFC Hacking] Beezy43:
I put one on the back of my ipod touch to toggle hotspot on and off.

I ended up having to tape my tag to the outside of the case because apparently nfc and metal do not get along. It looks a little crude, but it works.

I also put one on the back of my xbox 360 controller so that when someone messages me on the xbox I tap my phone to the tag and it opens the my xbox live app which is a breeze to type out a message in.

Also have the usual work/home/car ones as well

Sent from a Nexus Galaxy far away...
[NFC Hacking] hollywoodfrodo:
That is true, but you can get anti-metal tags that have a thicker backing on them to keep the metal from interfering without the need for the manual tape job...
[NFC Hacking] eMZi0767:
Tag

I reused one of inactive proximity cards. When it's used between 7:00-13:20 it activates "school profile", which does the following:

Disable Wi-Fi

Disable Bluetooth

Disable Mobile data

Stop music player

Mute the phone

If used between 13:20-7:00 it

Activates Wi-Fi

Umnutes the phone
[NFC Hacking] Beezy43:
Yeah I found out about them shortly after I did this, I'm going to order some and do it with them so it'll look better.
[NFC Hacking] yayitsthatkid:
Some of these are great! Haven't gotten around to buying tags yet, but looking forward to programming them. I didn't even think about putting an NFC tag on my keys. Genius! :highfive:
[NFC Hacking] thewarhawk:
I've heard a couple good ones:

Launch Metronome app tag on drum kit

Launch Tuner app tag on back of guitar

and my personal favorite: tag on watch/bracelet/in pocket that can make a fake phone call to you to get you out of awkward situations;)
[NFC Hacking] Hextall:
Quick question, I've seen in many different places about using NFC tags to start a timer (most popular being one on a laundry machine)... how exactly does one do this?

I have a timer app (so opening it is easy with a tag), but I'd rather have the time to count down programmed onto the tag and start when I tap it.

Edit: Nevermind... NFC Task Launcher has a set timer option. d'oh.
[NFC Hacking] svtfmook:
you may be able to find the activity in settings. so you'll have to shortcut to applications > open activity > settings app

[NFC Hacking] flammenwurfer:
I'm imagining a homemade game of sorts involving a phone or phones and a bunch of nfc tags. You could get a bunch (like 30-50) nfc tags, program them to display messages or play audio clips etc... You stick them to a large long board or the floor. Then you have teams and take turns throwing or sliding your phone across the board or floor and whichever tag it lands on will determine what your team has to do or how many points you get....
[NFC Hacking] mynameisNike:
An update recently in NFC Task Launcher app makes it easy to write a calendar timestamp - I put a tag on the top of my medicine bottle that allows me to to add the timestamp "RX". Before this, there would be times when I couldn't remember if I had taken it or not which always gave me the dilemma of skipping it or taking it accidentally twice. In that situation I can now just check my calendar.

The calendar timestamp might be cool also for someone who has to make timed deliveries or a number of stops during their job and would like a log of those, or anyone who wants to show how much time has passed between one event and the next.
[NFC Hacking] majingrim:
I use XBMC on my HTPC, and I use the official XBMC remote app to control it, so I put a tag on the back of my TV remote that turns on Wifi (in case it's not already on) and opens the XBMC Remote app.

I have another that goes under my bedside table, which is thin enough that the tag works right through it. The tag disables the notification light, lowers all volumes, and opens Sleep as Android, which I use as my alarm. I don't always wake up at the same time, otherwise I would have it set an alarm automatically. In the morning, another swipe turns the notification lights back on, and waits 10 minutes before turning the volumes back up so that a call or text wouldn't wake up my fiance while I'm still in the bedroom. Thanks to everyone who gave ideas!
[NFC Hacking] abejoker:
Any ideas for businesses?
[NFC Hacking] hollywoodfrodo:
The most obvious uses are for Retail businesses who can program their web address, facebook page address, or twitter address to be opened when tapped... Or tie in to another social/business website...
[NFC Hacking] abejoker:
Those ones I have. The foursquare check-in tap and another tap to Facebook. But I was trying to think many other uses. Can't think of them.
[NFC Hacking] Daemos:
I'm trying to figure out how to do this with one tag without tasker:

If touched again

do the opposite as above.

[NFC Hacking] punshkin:
I haven't bought NFC tags yet, but my idea is to hava a Tag on my bike, that starts GPS and tells the app MyTracks from Google to start logging my track.

Is this possible or can the NFC Tag only tell my Phone to open an app? If it is possible, which app would be the best for it?
[NFC Hacking] drumz0rz:
Anyone have any idea how you could store information on a NFC tag, for example plain or encrypted text. I'm picturing having a tag that when scanned, will prompt for a password, and if correct, display the information stored on the tag.
[NFC Hacking] hollywoodfrodo:
In theory this is a simple obvious use for nfc tags - the problem is that nfc tags are very limited in memory and most encryption involves adding a lot of additional characters into the text so right now it wouldn't be possible with the most popular tags because they wouldn't have enough memory. Down the line as tags with higher memory become more affordable and common place, there will certainly be options for this.

[APP] Badge NFC

Hello, for those interested I have posted on the Play Store a new application to use the NFC chip in an original way: Badge NFC

It 'a simple application that allows you to use an NFC sticker/tag as clock in/out. Place the tag where you want and whenever you touch the phone the app keeps track alternately of in/out actions, saving them in a database that can be export to Excel

https://play.google.com/store/apps/d...d=com.badgenfc

BadgeNFC for Android - Home

With PRO key ( € 0.99) you can save your in/out actions on an online database and share them with a group of people ... for example, a small gym managed by a group of friends could put a preconfigured sticker and record to the online database all the clock in/out actions ... of course everyone has to have an Android phone with NFC chip ... but I guess you do not associate with Apple boys ... ;)

I accept suggestions and / or criticism ... I'm not a developer by profession, only in my spare time ...

NFC Actions for paranoid people

Hello,

I've not seen such task but here is what i would like to do:

I wish to have with me an "Emergency NFC" which, if something is happening to me (robbery, burning building, etc) will make my phone send an automatic email to some people stating that i'm in danger and giving my location to them.

So, if someone knows how to do that, i'd like to read it :)
[NFC Hacking] OstrichSak:
So they know where to collect the body afterwards? Sounds to me that what you need is a concealed weapons permit, a small handgun and a bit of training.

Loving this thread so far guys.

I am on a rooted T-Mobile GS3 and I'm trying to achieve a fairly simple task but I'm not sure how to do it.

I'm using tasker with the hopes of:

Turning off wifi

Turning on a 3rd party wifi tethering app

Opening a 3rd party podcast app

Does anybody know how to initiate the wifi tethering app? I'm pretty sure I can get it to open but I'm unsure how to start it.

I read on in the tasker FAQ's that rooted phones have the option of input commands but I'm kind of confused on how to do it.

Thanks for any help and all of the great ideas in this thread so far!

update online spreadsheet

I just discovered that in google docs, you can create a form that will update a docs spreadsheet in real time with each time form is submitted.

use case: track beverage consumption

1) nfc tag for each type of beverage in fridge

2) swipe sticker,

3) entry is created for beverage drank in google docs spread sheet with time stamp

sticker launches URL for Google form, append the url to pre-populate form with beverage selection
[NFC Hacking] eg8hardcore:
Some great ideas in here. Here are the most common thingsI use my nfc tags for:

1 nfc tag sits under my sticky pad on my dash. Turns on GPS, Max brightness, and activates a hud app so I can see speed on my wind shield

2 nfc tag for car mode turns on bluetooth, activates driving mode for texts, opens music player

3 night stand turns notification on silent, activate alarm

4 vcard nfc tag embedded in my id tag at work with my contact info

5 nfc tag on my wall that my fiancee and I use to leave long messages to each other.

6 I work at Tmobile and I actually have nfc tags all over my store hidden behind posters, etc in order to have customers touch posters to open apps, or check them in on foursquare, or add customer loyalty events at or store into their calendar.

[NFC Hacking] Kerrowmoar:
This is what I am looking for - I want to place a tag inside each of the rooms in our youth centre so that the duty manager can swipe the tag as he checks the rooms & it will open google form allowing him to okay or highlight issues. How did you differentiate your drinks/my rooms?
[NFC Hacking] fred02171:
easy way -

in google forms

1) create multiple choice question for room (RoomA, RoomB, RoomC ect)

2) create a text question for your notes

3) from form creator, select responses, "get prefilled url"

select "RoomA", hit submit

this gives you a url that points to the form with "Room A" preselected

4) copy this url to your nfc tag that goes in "RoomA"

5) repeat step 3 and 4 for each room

dont worry about timestamp this gets created automatically

Harder Way- More Flexible

Make Multiple versions of the form

follow steps 1 and 2 above

3) save copy of form locally as html file repeat

4) edit in notepad++

5) comment out the choices that dont apply

for "RoomA" comment out RoomB, RoomC ..

6) Save as RoomA.html

7) Create a dropbox account

8 ) host RoomA.html in the public folder of your dropbox

9) log into dropbox, find "Room.HTML" right click "copy public link"

10) paste the link to your NFC

11) repeat for each Room

It boots right into the ROM, but the second I slide up the unlock slide the phone shuts down & restarts (100% of the time). Then, it just keeps bootlooping from then on.... It did this the very first boot when I took it out of the shipping box.

I can get into recovery by holding down the vol and power button, but recovery doesn't recognize the card at all (even though it works fine in my other phone/PC etc etc)

Is the phone defective??
