EDIT: Removed post containing link to Droid-Life article and NFC.apk files. They only would read existing NFC created tags, but would FC when trying to write new ones.

Please see DrMacinyasha's post below, as it contains a zip he compiled with this incorporated into the Settings menu for NFC. I flashed it (Foursquare works again yay!), and works great!

NFC Task Launcher won't write new tags FYI, but seems to read them okay. Maybe I'll try other NFC writing applications to see if those will create new tags.

That's scary. That means it could be even easier for people to hack.

I know you were hoping for positive responses but the dangers I've heard seem more feasible if you can read nfc with screen off. Sure it can have its ups.

I'm not trying to be a negative poster. I hope you don't take this the wrong way.

Fortunately, you can set it to what you'd like. By default, it is set to only scan when screen is on and unlocked. You can have it scan when screen is on and locked (what I like to do with NFC Task Launcher to quickly silence my phone when I get in to work in the morning) or have it scan every few seconds while the screen's off.

Again, by default it only works while the screen's on and unlocked.

Now, with that out of the way, I happened to compile AOKP with this mod built-in yesterday. Note that Foursquare is also fixed in these:

Tiny, not taken the wrong way at all. I completely understand what you are saying here, and presented a side I wasn't thinking of right way.

Yup, the fix for Foursquare was found by some folks for CM, and it was merged into AOKP the next day. Rather than waiting for Build40, I decided to compile my own B39 with that in it.

Roman retweeted you asking about that, and I noticed some wonky stuff too...so I'm glad that it was found and fixed. Thanks again for re-compiling it! It's working great!

does this mod add a toggle to aokp b39? and if so does the toggle turn nfc on/off to work while the screen is off or while the lockscreen is on? thanks!

Yes, there is an NFC toggle, so you can toggle it off/on from the Notification Bar. With NFC turned on, you can select if you want it to work/scan a tag with screen on but phone locked or screen off/phone locked, or the normal way (screen on then unlock phone).
