Look mum, no wires!
The low-down: These SD memory cards contain wi-fi transmitters, enabling wireless transfer of image files from a camera to a wi-fi network or laptop, pad or phone. The set-up files to link the cards to another device are on the cards themselves and set-up is achieved by mounting the cards to a PC to embed wireless security codes. It is a simple procedure. Whenever the camera with the Eye-Fi card is switched on and in the vicinity of a receiving device, transfer begins automatically. The devices can be set up to upload images to popular sharing sites such as Facebook, Flickr, Picasa and so on - the company says more than 1000 cameras will work with the cards.
Like: The Eye-Fi system works so well, it is a bit spooky. Just wander into the reception area for your PC with the camera turned on and a small window appears at the bottom right-hand corner of the screen showing the image transfer progress.
Dislike: Transfer speeds are slow compared with a direct copy from a memory card in a PC card reader.
Verdict: Kodak and Nikon brought out wi-fi enabled cameras a few years ago. They didn't arouse much interest, perhaps because they were difficult to connect to other devices. Now the camera companies are revisiting the wi-fi enabled form, with Samsung leading the way. Our guess is that next year most new cameras will come with wi-fi, but there's no need to turn green with envy - the Eye-Fi card is a way to make your present camera into a wireless device.
