It doesn't use any power unless its in use.

If that's really true, why do they disable it when the lock screen is on or the screen is off? It must use some power to scan for NFC tags, unless it's just magic? Since an NFC tag doesn't have a power source, I have to assume the power is coming from the phone, not the tag, right?

That's a privacy reason to prevent the use of malicious NFC tags, which is why its off by default.

Here is the nfc.apk from sonics freegs3. This is for sprint LG8. This mod is awesome!

As long as it is not sure if the official mod is compatible with LG8 and until I had the time to download and deodex the LG8 firmware I provide you my mode based on stu5797's Nfc.apk.

But I cannot guaranty anything because the source is not from myself...

I tried this on my Verizon S3. All I did was flash it with CWM and it works! At least I hear the bing noise when I try my work ID (with the screen off). I'm still waiting for my NFC stickers to come in the mail to program things... Awesome work! I almost scrapped some of the NFC automation projects I had planned as I didn't want the extra step of turning on the screen and unlocking the phone.

    In the Samsung Galaxy S3 Stock ROM NFC does not work when screen is off or locked. With this mod NFC also works when screen is locked or off.

    There are two versions. The first just enables NFC, when screen is on, but it also worked when it is locked. Also with a PIN or Password-Lock everything is fine. But it disables NFC when the SGS3 is in standby and the screen is off.
    The second version let NFC active all the time, even when the SGS3 is in standby and the screen is off.
    Nothing else is changed in the behaviour of the NFC.
    There are also two zips to go back to stock NFC, one is odexed and one deodexed. Use them only with the right firmware version (for example VPALEN).

    All ZIPs have to be flashed with CWM. You should wipe Dalvik cache after flashing.

    This mod works for at least for the firmware SPH-L710_VPALEN. This mod does not work with LFB now. I will provide an updated Mod in the middle of August because I am at vacation now.

    Please give me feedback, because I do not own this device and I cannot test the Mod on it! I just ported my MOD for the international S3 to the L710.



    Disclaimer: As always, I hereby absolve myself of responsibility for any damage you cause to your phone by flashing this. There is inherent risk in modding your device, and by flashing anything in this thread you are taking that risk into your own hands. If something goes wrong, I will try and help. You should always make a Nandroid Backup before flashing.

    To ROM Devs: You are more than welcome to use this in your ROMs! Just shoot me a little bit of credit in your release post!

    Thank you: Geniusdog254 for the idea and the infos in your thread.

    Thanks

    here is the mod for LIH created from your Nfc.apk.

    anyone test this on the final sprint lj7 release? does the LIH version work? (I am assuming it will since the nfc.apk is not likely to have changed)

    Just tested - the LIH screen off version DOES work on lj7. (Oh, and with the official lj7 being out, no reason to do an li3 version.)
