The technology requires a separate receiver, but delivers a theoretical bandwidth of up to 560 Mb/s with effective throughput rates reaching 375 Mb/s.
As a close proximity wireless data transfer technology, TransferJet has only a range of a about 1.5 inches, but could alleviate the pain of switching memory card. The technology operates in the 4.48 GHz band and was introduced in 2008. It has been ratified ISO/IEC as international standards ISO/IEC 17568 and ISO/IEC 17569 this year.
The SDHC card announced by Toshiba is expected to be a prototype. There was no information when the device could become commercially available and how much it could cost.

Already I can imagine having a miniature turn-table loaded with SD cards. Simply turn the wheel to switch cards, like one of those ancient slide projectors but with SD cards instead of transparent plates.
How is this at all helpful? Its range is 1.5 INCHES and requires a receiver, or docking station. My USB cord is 6 feet... And just as fast. I can get a docking station. This is as silly as those "wireless" charging pads.
There's a reason no one has touched it since it was introduced in 2008.
You already can, if both devices have NFC, and you can transfer to PC with WiFi synching?
This is not for transferring data between the card and a computer, it would be an incredibly stupid concept if that were the case. This is for use with content creation devices. If you are shooting video and one card is close to being full, you can switch cards seamlessly without interrupting your shoot.
+1 this is what the tech is really all about. Being able to transfer stuff in between anything that has the tech and transfer near usb 2.0 speed.
rrrubyYou already can, if both devices have NFC,
Well NFC shouldn't be doing the syching. If it is, that's some slow transfer speed. (somewhere in the area of 400 kbit/s.)
As for Wi-fi syncing, will it's fine for the PC, how about getting data from "Phone A to Phone B" without the need for PC?
That's what the comment you quoted was talking about.
Yeah you could get everything you need from a PC on a wifi network, but what if your with a friend and both of you are no where near a pc and/or near the wifi network that it's on (say the middle of town, in park, or in a store)? Also what would you do if your friend wanted to give you something without notice (maybe a video on his/her phone that was taken not to long ago)?
Unless your taking a laptop everywhere, This is one of the advantages of the tech. No PC or WiFi middleman. Just transfer to other mobile device and go.

Well you haven't looked into the tech very well if your complaining about the range being 1.5 inches.....
SD card in camera to Smartphone anyone?
As for why is hasn't taken off yet, I would have to say it's because of poor marketing. I haven't heard about this at all until a few months back and i've been constantly on tech sites such as tom's since late 2008.
Maybe i was just somehow (without knowing) turning my head away from it. Although I'm doubtful of that as I'm able to keep up with even the rumors of unreleased cpu's and gpu's from Intel, AMD, and Nvidia.
So, marketing is to blame on that front.
Since the wireless is built into the SD card, it ceases functioning without power. So if you pull the memory card out, you're back to square one. Why not just plug a damn cable into the camera, and transfer that way? Or use a camera with 2 card slots? What about the battery life of the camera? 64GB stores a decent amount of footage. If it uses CF you can get a 128GB card.
