Nothing groundbreaking here but new to me.
I knew about is technology but I had never seen it in the one package before.
Plugging an SD card into a USB dongle and shoving it into your computer is hardly an innovation. Your phone also has a USB port in it but it needs to be an “On The Go” or OTG device in order for your phone to recognise it.
I have just found this:
This allows me to grab the SD card from my camera, use this, transfer the images to my phone (yes I do prefer to use a real camera rather than a camera phone) and then process and upload them to where they need to be.
This little beauty (when I purchased it from Amazon) was only £6.99.
