Abstract
A system and method for simply and securely pairing two Bluetooth devices. A Near Field Communication (NFC) read-only tag is placed in a first Bluetooth device such that a user of a second Bluetooth device can pass the second device near the tag, which then transfers encryption key data for the first Bluetooth device to the second Bluetooth device. An algorithm is employed for initiating the pairing process with the first Bluetooth device, which can ordinarily remain in a silent mode for security reasons. Once the pairing process has been initiated, and the second Bluetooth device has been passed near the NFC tag, the pairing process is completed with no further action required by the users.
