2mm QR codes according to the article:
> The protocol used at Fukushima is automated. Each bee is equipped with a 2-mm-wide QR Code which is read by a camera, activating the opening of the maze.
But yeah, doesn't look like a QR code at all, are there possibly different variations of QR codes? Haven't heard about that myself.
- blueflow 1y agoI can imagine the journalist referring to all Matrix Codes as "QR".
- wanderingstan 1y agoThis is it. All matrix codes are now commonly referred to as “QR Codes”. I’ve noticed this especially at airports where both passengers and gate agents refer to the “QR codes” on boarding passes. (Which are IIRC Aztec codes)
- alex_suzuki 1y agoBoarding passes are typically Aztec, but don‘t have to be. IATA allows other types as well: https://www.iata.org/contentassets/1dccc9ed041b4f3bbdcf8ee8682e75c4/2021_03_02-bcbp-implementation-guide-version-7-.pdf https://www.iata.org/contentassets/1dccc9ed041b4f3bbdcf8ee86...
- thaumasiotes 1y agoIn China the normal word is 二维码 "two-dimensional code".
- noduerme 1y agois a barcode a one-dimensional code?
- collingreen 1y agoYes - even though it obviously has visual height the data only runs in one dimension. For the 2D codes like QR the data is in both directions, which is why orientation often comes up in their design.
- alex_suzuki 1y agoThere‘s MicroQR, which is just a single finder pattern of a regular QR code, with some adjoining data. But it doesn’t look like one.
- ChrisMarshallNY 1y agoAnyone remember these? https://en.wikipedia.org/wiki/High_Capacity_Color_Barcode https://en.wikipedia.org/wiki/High_Capacity_Color_Barcode Haven't seen one in ages.
- alex_suzuki 1y agoNever saw one of those in the wild. But I have seen NaviLens codes (on cereal packaging), they use color as well: https://www.navilens.com/en/ https://www.navilens.com/en/
- randall 1y agothey’re at every new york subway station. i don’t know why.
- ChrisMarshallNY 1y agoSurprised that they are still there. It’s an old Microsoft standard. I’m pretty sure that MS rolled it up, years ago, so they may not be valid, anymore.
- joecool1029 1y agoThey are Navilens, new thing: https://www.mta.info/accessibility/innovations/navilens https://www.mta.info/accessibility/innovations/navilens
- ChrisMarshallNY 1y agoAh. That makes sense. Different look, though. The Microsoft ones used triangles.
- randall 1y agooh cool it’s an accessibility thing! had no idea.
- diggan 1y agoWe have something similar in Barcelona (maybe entire Spain? Apparently called NaviLens, colored squares rather than triangles) all around public transit points. They're used for blind people to navigate the public transit system :) > As users sweep their environment with a smartphone, audio cues allow them to find and center the tag in the phone’s field of view. A shake of the wrist prompts the details contained within the tag to be read out (visually impaired people are often holding a guide dog or cane with their other hand). https://www.technologyreview.com/2019/06/06/135057/these-colorful-stickers-are-helping-blind-people-find-their-way-around/ https://www.technologyreview.com/2019/06/06/135057/these-col...
