In early 2008 Sony unveiled a new technology called TransferJet that allows wireless data transfer. Now, Sony has begun incorporating the technology into its Memory Stick memory card format, enabling owners of Sony digital cameras to transfer data without needing any cables.
TransferJet is a technology that allows wireless data transfer at speeds that rival Wi-Fi, but only across a very short distance (3cm/1.25in). This means two TransferJet devices need to be essentially touching for transfer to work, but it also provides an element of security, since a thief would likely have to be able to steal your device physically before they could steal your data.
Some of you might be wondering what the difference is between TransferJet and Bluetooth. The main differences are transfer rate and range. Bluetooth transfers at up to 3 Mbit/s while TransferJet boasts 375 Mbit/s. The extremely limited range of TransferJet also solves many of the security issues that have plagued Bluetooth.
Sony loves to make their gadgets play well with one another, and you will begin seeing Vaio notebooks with TransferJet technology soon. Other computers may require special receivers to place your cameras on.
