The Bluetooth wireless communications technology has become commonplace these days -- almost in spite of itself. While Bluetooth can be exceptionally useful for short-range communications, it can also be an enormous pain to use, in particular because of the pairing process users must go through to connect devices for the first time. Enter the new TransferJet standard, which is being backed by a number of digital camera makers who want to simplify the transfer of images and video. TransferJet can operate at speeds up to 357Mbps, 100 times faster than Bluetooth, and it doesn't require any pairing, it simply kicks in automatically and begins transfers when a compatible device is placed within 2 millimeters of the "transfer area" of a receiving device, like a PC. The cumbersome pairing process from Bluetooth has been replaced simply by proximity -- the thinking is that if a device like a camera can be placed within 2mm of a receiving device, the owner is okay with the transfer. While obviously this sort of security doesn't work in every scenario, it's good to see engineers learning from the usability foibles of previous technologies.
