For example, pairing a Bluetooth headset and mobile phone would be achieved by turning on the headset, selecting Add Headset from the phone's menu, and then watching the phone while it finds, connects and pairs with the headset. Additional security is provided by allowing the initiating device to generate a six-digit passkey that must be entered on the other device. Once entered, there is no need for the user to remember the passkey. The standard will also support the use of near field communication technology which allows devices to be held in very close proximity to trigger pairing. "We brought together usability, technical, security and marketing experts from our member companies and developed a system where the initial one-time pairing of devices can be done in a matter of seconds with fewer steps," said Michael Foley, executive director of the Bluetooth SIG. "This new version makes pairing Bluetooth devices easy for anyone to do. We also significantly increased security of the pairing process and kept the impact on device and silicon manufacturers to an absolute minimum, to maintain low cost and continue the high degree of innovation for Bluetooth products," he added. Bluetooth 2.1 + EDR further optimises power consumption through a feature called Sniff Subrating, which Bluetooth SIG officials claim will increase battery life by up to five times in products such as mice, keyboards, watches, home sensor networks and medical devices.{moscomment}
