So there was this weird square barcode-looking thing in my magazine and Ro saw me puzzling over it last night and casually said "Oh you need a QR reader like Qrafter." When I just blinked at her, she sighed, grabbed her iPad, found and installed that app, and scanned my magazine page, bringing up a url for the ad, among other things.
I sat and blinked some more. Then dumbfoundedly asked how the heck she knew that, and she pulled some barcoded classwork paper out of her backpack (I had actually seen it this week but had NO idea what the attached letter was talking about) – scanned in the barcode box on the paper and it brought up a video she had made in school thanking some kid for coming to her class and showing them all how to scan, create, and print QR codes.
Please note the date that the seven year old moved ahead of me technology-wise.
