day 44: qr codes

that's right. i found a qr code on my banana. it was a gross banana, fyi.

which leads me to think (qr codes, not gross bananas) that is there anything that doesn't have one nowadays? and do people actually use them? because, i don't think i really need to see what the banana sticker qr code site has to say, or the poster for produce in the grocery store. or maybe i just need a few more hours in the day to examine where they all might lead me?
