QR Codes and Barcodes As Fast As Possible

Scannable codes, once the sole province of the grocery store checkout aisle, are now everywhere thanks to the rise of smartphones. How have they changed over the years?

Yeah. Me too. Now i know it is invented in Toyoto subsidiary in Japan. They create it so that they can sell their cars more easily. Because barcodes takes too much time.

[@urban0443]

Btw QR CODE is actually invented in Japan for Toyota Cars.

[@jackkraken3888]

The venerable barcode is not going anywhere, its still very useful in the retail space and is basically just a quick way to read a serial number , which itself is often written at the bottom of the barcode just in case the barcode is damaged or unreadable. Also the barcode rarely stores anything more than just a serial number, the rest is stored on a database on a computer. While QR codes are great, they still need more high tech devices, barcode scanners are often cheaper and ubiquitous and very easy to use. Also barcode scanners are moving away from lasers for reading as the lasers could be harmful if pointed at the eyes. Newer models use LEDs and are still pretty accurate.

Could you make an as-fast-as-possible on projectors and prjectorscreens/paint etc.?

[@chris195868]

While UPC is probably the dominant barcode type in the US and Canada, EAN is by far the most common in Europe, with the most common one of those being EAN-13. Also, QR code scanning has become insanely fast, without using the cloud. In my group at university we are working with qr and bar code scanning libraries that don't connect to the cloud, so all the processing is done on the phone. The two limiting factors for all the phones we have tested are camera launch speed and autofocus speed, since the processing itself is instant.

[@daemiax]

+Christoffer Nørskov Datamatrix is getting more common , also I think code 128 is as common as EAN-13... and thankfully none of that crappy interleaved 2of5

[@chris195868]

Daemi Ax I have seen datamatrix a couple of places, but often for more specialty purposes, would say QR is still more common for the consumer to see. Don't think i have seen code 128 (or recognized it) anywhere. At least products in the store still use EAN 13 here.

[@hustlesprouts]

Hey Chris do you still dabble in QR codes?

[@IDontDoDrumCovers]

Nah qr codes mess up way more than barcodes in retail. One wrinkle and it's dead. They're also slower to scan. I'm a checkout opporator they drive me and everyone else nuts. Apparently all the other departments like them though >.>
