This is a mod NFC service that runs at boot. It allows you to scan NFC tags either with the screen totally off, or with the screen on but still at the lockscreen. By default nfc will not work unless the screen is on and unlocked. download one of the zips below, and flash it via recovery (tested with Omega Rom). To restore to stock, just pick the stock version.
Also build JUBMG3 and onwards has a further feature which allows NFC payments to work on deodex roms. credits to romracer, for the original mod to disable the signature checking
any feedback appreciated.
Remember to backup before flashing. for that just it case situation.
p.s. remember people that leaving the NFC on all the time can leave you phone open to security breaches. so please be careful when using this mod.
