Near Field Communication (NFC) can be used to share the data needed for OOB pairing, and thus provides a convenient and secure means of establishing Bluetooth connections. Indeed, the short communication range of NFC contributes to both security and selectivity. Remote attacks are not possible when the unauthorized party needs to be physically present within a few centimeters of the equipment, and tapping allows the user to be quite sure that only the device to be connected has received the key.
