A method and system for interrupt based NFC pairing is provided. In a passive NFC tag comprising a primary coil and a secondary coil, an electrical signal may be generated in the secondary coil when an NFC reader energizes one or both of the primary and/or secondary coils. The generated electrical signal may be filtered to remove any undesirable signal components such as noise. An interrupt signal, which may initiate pairing, may be generated based on the generated electrical signal. An NFC tag identifier, which comprises an address of the remote control, may be communicated from the NFC tag to the NFC reader and this may initiate the pairing on the NFC reader. The communicated NFC tag identifier may be utilized by the NFC reader for the pairing. The NFC tag identifier may be over-written with a new NFC tag identifier and the new NFC tag identifier may be locked.
