It’s possible to add WiFi to any camera, including that old DSLR sitting on your shelf.
in this video, I show a simple but clever SD card that has built in WiFi and allows you to transfer pictures from your camera to your phone, tablet or laptop without connecting any wires and without installing any apps.
Wi-Fi enabled SD cards are quite a bit more expensive than their regular counterparts but they’re extremely convenient if you want to be able to access and share your photos while on the go.
I’m using the Transcend 16GB Wi-Fi SDHC card but there are other manufacturers who also sell similar products.
For the techies out there, believe it or not, the card is actually running a Linux OS and you can get root access to install extra scripts and apps. Of course it’s quite limited due to the low-power CPU and small amount of RAM.
