    I just saw the new Blackberry Tag commercial on the front page. I know very little about NFC, but it occurred to me after seeing this (and the Samsung ads showing NFC-based file share), that phone cases could conceivably be a problem for NFC. Does anyone know if the signal is strong enough to go through a case or if this might be a problem?

    Good question, as the add shows the phones with no case for advise reasons. I think it may work as the cases are made of thin plastic, just may take a bit longer for the signal to transfer.

    Well back light has to be on for NFC to work, and the Tags take there power from the phone. I have a BB leather slip case and when I pull phone half way out, back light comes on, and I can activate A NFC Tag through slipcase. So I think plastic will be ok.

    NFC is working based on 13.56 MHz frequency. A signal with that frequency gets absorbed by metal and water.

    So leather and plastic cases are fine and don't effect the NFC signal.
