QR code vs Barcode

[RoZpr0]

Hey guys,

I am an intern in a huge company and i have been given a task to research QR codes and Barcodes when it comes to the ease of usage especially in hard environment like not enough light, huge storage rooms with lots of equipment.

 

I found that QR code is "visible" from 360 degrees which makes it easy to scan codes from difficult to reach places, but light factor is important as well.

 

Does anybody has any experience or knowledge about how light access (or its lack) affect the readability of QR code and Barcode?

 

Thanks in advance.

As a Amazon employee who deals with barcodes LITTERALLY every 3 seconds of the day...  regular barcodes reign supreme for a reason.  They are durable as fuck.  Get a smudge on a QR code and see how well it scans.  Barcodes are scan and go, QR codes have to be lined up and require a special technique that someone may, or may not, be able to develop.  This doesn't include the price of the equipment to actually perform the action.

Well light does not affect how the scanner will pick it up, as long as the black on the code can be differentiated from the white of the paper. That is the key here.

bar codes were made to that they do not smear when being fast-printed at 50mph

they originally were a circle that could be scanned 360 degrees but it would smudge, so thats why its now lines

QR codes will smudge in the same way if they get fast printed

 

the original circle bar code:

i say just do some tests. print out some QR codes and barcodes, turn the lights off and see what happens

you will have to do this anyway if you want to be able to say that you have an answer

From my experience Barcodes should also be lined up, and it was harder for me to scan barcodes when they were located in hardly possible to reach places.

When it comes to durability thats true, barcodes are way better here.

Barcodes and QR codes have their purpose, however what is that purpose in this case?

 

Generally I'd think QR codes are best for doing something quickly or for something in place of using an NFC tag. Barcodes best for checking in/out something or for products.

[RoZpr0]

The case is checking in/out products, finding them in any location and being able to assing it to a group of other items.

What I meant by groups is for instance, few different products (each one of them has its unique barcode/qr code) are grouped together using software (any ideas for a good one?).

Later on when scanned it will pop out that it is a member of this particular group and also when it was checked in the company etc.

Huge amount of products are stored for instance in storage rooms because they are outdated but still need to be checked for any purpose and then the problem of access is valid same with light and angles

There are also cases where the barcode is printed in a crappy position. 

especially sucked. The lines were printed horizontally, over the ripples, meaning you had to hold it perfectly sideways and line it up perfectly so the scanner can pick up the lines just right.

Fuck blk water.

now that i think about it, if you buy a proper modern scanner i don't think that light (or orientation) will ever be a problem, because it should use a laser to detect the code, and not ambient lighting

 

 

look at that shit. awesome. from now on i'm a barcode scanners enthusiast

[DEDRICK]

It really comes down to the size of the barcode and the type of scanner you are using.  Some barcodes are a pain in the ass to scan when they are printed beside other barcodes.  Apple likes to use REALLLLLLLY tiny  barcodes which are impossible to scan to begin with, then they put 2 of them beside each other as a big **** you.

 

I just tested a barcode in a near pitch black room using a Motorola MC9090(Short Range laser) and it had no issues

Thanks a lot guys I will consider the ideas and forward those tomorrows on conference Will update you with the resolution achieved within company

I promise you that barcodes are FAR easier to scan if you have a SCANNER, not a camera on your phone.

That depends on the scanners, the use case, and whether or not it's going to be rapidly scanned. 
I have a scanner at work that scans both barcodes and QR codes, and it's amazing for bar codes. 
But some of the other scanners have to be lined up perfectly to work. In that case, a QR code might be better, but in most cases a barcode is better.
