SIMPLIFIED DEVICE PAIRING EMPLOYING NEAR FIELD COMMUNICATION TAGS
First Claim
1. A method for establishing secure wireless communications between two electronic devices, said method comprising:
- providing a first electronic device which uses a protocol for wireless communications with other devices, said first device containing a Near Field Communication reader/writer;
providing a second electronic device which uses the same protocol for wireless communications as the first device, said second device including a Near Field Communication read-only tag which contains secret information about the second electronic device;
passing the first device near the second device, such that the first device can read the secret information from the Near Field Communication read-only tag;
triggering the second electronic device to temporarily switch from a non-discoverable mode to a discoverable mode;
transmitting the secret information from the second device to the first device in order to initiate the establishment of secure communications; and
completing the establishment of communications by exchanging additional data as required by the wireless communications protocol being used.

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.

16. A system for establishing secure wireless communications between two Bluetooth-compatible electronic devices, said system comprising:
-
a first Bluetooth-compatible electronic device containing a Near Field Communication reader/writer; a second Bluetooth-compatible electronic device including a Near Field Communication read-only tag, said tag containing secret information about the second device, such that the first electronic device can read the secret information from the tag when the first electronic device is placed near the tag; and a triggering mechanism for temporarily causing the second electronic device to switch from a non-discoverable mode to a discoverable mode. - View Dependent Claims (17, 18, 19, 20)
