    I know that on lollipop trusted device i can add a trusted NFC
    i actually don't have a NFC tag, but i can buy some

    as far as i know NFC works without power and you usually put the phone very close to NFC tag so it can be recognized

    I'm wondering how phone lock up again? Does it start like a timer before auto lock?
    Do you need to touch NFC tag to lock it up again?

    Does NFC phone sensor use much battery?
