LZeal releases ezShare wireless SDHC card with a Wi-Fi on/off switch

It's very low transmit power, probably less than 1mW (.001W).
Even still, power consumption is a concern, hence the switch.

Hopefully the majority of uses will allow access to it without accidentally being bumped into the wrong position.

@reddog: it is more like 0.23w
@squire: the standard is all nice, but if you were a camera manufacturer, would you necessarily prioritize battery life in your camera design, or design a camera for anything the world can throw at it in an SD slot?
Before we go any further, let's try and google to see how much a memory card draws, and how much THIS card draws.

@Timmbits .. It's very good question.
As electrical engineer, my major concern here is the heat generated by nearly 400mA, given the very small nature of the SD card, and that it is in a closed compartment, where you don't have the ideal situation for heat dissipation.
Such heat, especially during warm weather conditions, could destroy the card, but excessive heat could also damage adjacent components, depending on what is adjacent to it.
The warranty might become a fight between camera & card makers.
To make things worse, the SD Association has not released a Wi-Fi SD spec, but I believe they already have a draft, and I think that Eye-Fi, and other Wi-Fi SD makers (members of the Association) have already said they would not accept or abide by this standard.
300 or 380 mA is a lot of power for an SD card in a confined environment.
What is next? Are they going to install a cooling fan for the card?
It's of course best to have wireless off until you are ready to transfer the files.

@John Diggers
Your two combined posts are very well said. Lots of folks whine about the Eye-Fi cards, when really there is nothing wrong with them, it's mainly user error. However, much of that user error is brought about by the not too clear instructions that accompany the card, and even on their website things aren't as clear as they should be.

But once you have spent time (far too much in my opinion) on their site and on their forum and worked out all the permutations, it's a wonderful and robust product. I should say that I am referring to their new X2 cards; the previous generation had lots of problems.

The irritation of having to log-in to an online account to change settings, I think is just a way of them controlling things i.e. to prevent Chinese/Far East IP theives copying their product. I don't particularly like the irritation but I accept it because it protects consumers from buying junk copies from the likes of eBay (who admit that most mem cards on the site are fake).

@John Diggers (Part II)
I am also grateful to you for pointing out the shortcomings of this new ezShare card, which I first discovered about two weeks ago at this online retailer: http://www.gadgetinfinity.com/wi-fi-card/

Sure you can if you have a notebook/desktop computer nearby. but if you only have a ipad/smatphone around?

I don't see why you couldn't do it with a tablet device, provided you have the necessary software and storage capacity.

Exactly

There are some who prefer Non-Communist sourced goods.

Also it's a memory card as well, so you can remove it, turn off wifi, and put it back in as just a memory card.

You are not alone, me too is having problems with Eyefi cards.
Also I dislike their software and the fact that you need to login to be able to make changes to the eyefi card settings.

It would be nice if DPReview could do a review on these new wifi sdhc cards.

No!! you're not unlucky.. it's the manufacturer of the crude made EYE FI CARD which is now very unlucky for there's a new and reliable one just came up.and with a brillant idea to provide an on and off switch on it.
