This is not the first wireless memory card reader we've ever seen, but such things are uncommon enough that we had to stop and spend some time on it.
Created by I-O Data, it can read SDHC and SDXC memory cards and supports 802.11 b/g/n Wi-Fi, putting the top transfer speed at 150 Mbps.
That means that the connection can be just barely fast enough for 720p video to be streamed properly. Of course, it is much more likely that owners will just copy a whole file before playing it, but it is good to know the option is there.
I-O Data has managed to make its idea work by turning the card reader into a sort of short-range WLAN router.
All modern router security features are supported, as are three simultaneous connections. An iOS app is used to manage files on Apple devices, and there should be similar programs for Android and Windows. If there aren't, there should be some soon.
The price of the NUBES, as the memory card is called, is 4,180 Yen / $50 / 40 Euro. It includes a 1,350 mAh battery that lasts for 4 hours (recharge via USB).
