The Eye-Fi, the SD Flash card that adds Wi-Fi to any camera
The Eye-Fi is a very cool product that combines a compact SD card with a built-in Wi-Fi Transmitter. The whole product is built on the tiny SD card. In other words, it is physically the same as any other SD card, but it has the Wi-Fi functionality built on it.
SD cards are basically becoming the standard on many digital cameras given the compact size, the large capacity (now you can find cards up to 32GB) and its cost (they are way cheaper than Compact Flash, Memory Stick and other popular formats).
To explain how this works, let me explain how it will work for me. I own a Canon G7 that has a SD card slot. If I had one Eye-Fi, I could simply set it up once to my computer and WiFi router. From that moment on, any time my camera is turned on in a region of my house covered by my router, my G7 will automatically start to download my new pictures into my computer. Since I take many photos every week, this is a true blessing and one that prevents accidents such as accidentally erasing photos that I have not downloaded to my PC when I run out of chips.
In summary, a great and very innovative product. The only caveat, its price: its $100. Read another article from gizmodo on the Eye-Fi here.
