Of course you could just write on a sticker with a pen, but where's the fun in that!

    And once you've got the QR codes on, you setup a pi with a camera than can read them and give you the results, maybe with a red/yellow/green LED for age :-)

    Brilliant idea. I really should start labeling stuff like that, I've used some handwritten notes but QR codes sound a lot easier to plop in a database.

    Are they full data containing QR's (they have all info text contained within the code) or do they link to an external database/software that tracks them?

    What do you use to print/stick the QR code?

    Not OP but for sticking you can probably get square labels from Avery, or be lazy and print on printer paper and use packing tape to adhere.
