As somebody who still remembers the time when making a phone call involved sticking your finger into a dial and rotating it like you see in the picture that follows

I was absolutely shocked to see that a free app I downloaded onto iPod Touch 5 to make book lists (nerd thing) grabbed the bar code of my book and immediately had all of its information. The app somehow knew when it was pointed at a bar code (as opposed to being pointed elsewhere) and just grabbed it. I didn’t even have to press any buttons.
I’m so disturbed by this that my knees are trembling. It’s phenomenal how far technology has gone in such a short time. I have no doubt there are endless possibilities that I don’t even realize hidden in the devices I use.
