Walking into Technology

It's not easy being old. One of my learning curves has been learning the new world, at least new to me, of technology. Just getting my books ready for posting on Amazon took four times longer than I thought. Today I learned about a "QR" code. It's that little square that when I take a picture with my phone, takes me to places I didn't know existed. Now each book has a QR code. Still not sure exactly how to use it, but I can learn. This old dog is learning new tricks.
