Bluetooth Secure Simple Pairing Makes It Into Devices

Many many years ago, Bluetooh version 2.1 updated its security scheme to something referred to as "Secure Simple Pairing". Not only was the process made more secure but also a bit more user friendly. Recently, I have started seeing devices using the Numeric Comparison protocol for pairing (e.g. the Nokia N8 and also a recent Samsung phone) where it's no longer necessary to enter a PIN but just to verify that the same number is displayed on both devices. Very neat!
