Supermarkets really need to get with the times. I mean, barcodes? Please. It's like they're not even trying.

- daveslash 4y agoSeriously. We're soooo over 1-d barcodes. Need to get a QR code on all that stuff. MMmmmmm.... Fiducial markers - that's hot
- Gigachad 4y agoThey usually use 2D barcodes for weighed items at the deli.

- marginalia_nu 4y agoPretty neat. You can encode 100 megabytes of data in a 4x4x4x4 cm tesseract, just need to apply an appropriate rotation around two of its axes and then you can extract the information as it intersects with 3d space.
- mikrl 4y agoThat adds an additional temporal component to the scanning process which makes me hesitant. However, the idea is ridiculous enough to greenlight.
- smitty1e 4y agoJust go full panopticon with a thousand cameras, so that the looters don't need to put in all that selfie effort.
- colejohnson66 4y agoThat’s Amazon Go.
- Lapsa 4y agoafaik some of them use quite cool tech - fully automated sensors for just about anything plugged up to complex workflows and whatnot
- Doxin 4y agoI mean you joke, but a local sports good store has switched to using RFID tags for all their products. First time I went shopping after the change was rather startling. I dumped my purchases at the cash register and almost immediately the cashier read me the total. I see no reason supermarkets couldn't do similar once this sort of tech gets prolific enough.
