I work as a cashier at a grocery store, and I have always wondered how a barcode scanner works. The one thing I would love to see is how they are built
I have a question: the angle of approach doesn 't have to be perpendicular, although the scanner detects the beam after reflection. I always learned in optics that the angle of approach is the same as the angle of reflection. How can the scanner then detect the reflected beam?... sincerely, Bart
Hi Bart! Thank you for your question! A photodiode is able to pick up the reflected light from the barcode that goes back-and-forth between the mirrors. :)
@@twowaymirrors Think of the self-checkout machines in supermarkets. What I could imagine is that the machine is in "nothing recognized" status at the beginning and it keeps scanning for barcodes at a certain rate. When you put a bottle of beer in front of the scanner, it enters "beer recognized" status. Then it keeps reading the barcode but it won't regard it as a new one until its status returns to "nothing recognized". However, the scanner is not guaranteed to recognize the barcode on every scan, so even if you keep holding the beer bottle at the scanner, it might return to "nothing recognized" status by mistake. This is the case the time-delay mechanism could help with --- when the machine is in "something recognized" status, it won't return to "nothing recognized" until the scanner has been recognizing nothing for a certain length of time...

i would like to use a bar code for an art project and stretch it to make a look like a pillar. So the lines are only getting longer but not out of proportion otherwise. Will people be able to read the bar code with an app or will it not work if just a section of the entire width of the stripes are scanned?
As long as you can see the barcode in it's entirety horizontally (left to right; first line to last) I don't see why it _wouldn't_ work ... it's not like some lines are fatter on top and skinnier on bottom, so it should only need to read the arrangement of lines in between the first and last line no matter what vertical point it's at on the barcode. If that makes sense lol 🤷♂️
Hi I am looking to start a theoretical project that involves barcode tech and have some questions. I will be in contact soon. I am very interested in the possibility of barcodes that are invisible to the naked eye but can be picked up by the scanner.
hey! it was a nice video but I have a doubt ....could I able to change the color of the text on the screen after it decoded for each product or the same product family..! example 1,2,3 are green and 4,5,6 are red so on and so forth...!
Hello. Very interesting video! especially the mirrors. I'm the R&D guy at Patriot Fluid Power. We have a qr code scanning web app and some of the people in the office just aren't as efficient with the camera in the iphones. I would love to chat with you.
I have my barcode scanner tied to the circuit that cuts the power to the scanner when the label maker prints the label. Once the label is removed the power is back on and the barcode scanner and key board will turn on. My challenge is that the Barcode scanner doesn’t come back instantly after you remove the label and takes 11secs to turn back on. Do you know a setting or a device that can help me eliminate this delay!

So the light doesnt read a barcode, It just uses red light to see the code? Im confused as how the red light captures data. Ide also like to know how the lines are translated by the computer.
Sir, Hi. Do you know how much MW on avarage are the laser machines in grocery stores where you put your products code bars to check the prices?, the ones that are posted on the wall in some sections. I was wearing some tinted prescription glasses of security that I use in work, they are made of some sort of plastic so my concern is... When I checked the coding bar ( bar codes) of some socks, the plastic bag which I placed underneath ( very close to the mirror where the laser beam is ) the machine red super bright laser reflected / shined ( indirectly and without a particular pattern, just everywhere ) on the surface of the white sticker where the code bar is and the bag surface and my eyes hurt in that moment. Did I possibly cause damage? Because I was wearing plastic security regular tinted indoor outdoor security glasses and my retina could possibly be in that moment more open and vulnerable to exposure due the tinted feature and the shine of the laser in the surface of the plastic bag and sticker reached and hurt momentarily my retina? I saw the beam shine for 3 to 4 seconds. Thank you for your time

Great video. You said the software has a time-delay program that helps prevent double scan. Do you have any details about how it works to prevent it?
That's a great question! It's probably programmed into the software with a timer delay function.

What’s the maximum distance can the barcode scanner could scan it ?? Any possible to scan an item which is in bags without taking it out ?
It's theoretically possible at any distance, given the proper optics.
our scanners' maximum distance is 20m

Depending on the scanner you chose for the application, it can be short range to very long range
This is such a great video
Thanks so much!
Nice video..i have a doubt that how these black and white is being identified by the laser beam ?
The image bounces back to the sensor, allowing detection.

What exactly is an optical scanner and what are its primary functions??..
An optical scanner is a computer input device that uses a light beam to scan codes, text, or graphic images into a computer or computer system
So the light doesnt read a barcode, It just uses red light to see the code? Im confused as how the red light captures data. Ide also like to know how the lines are translated by the computer.
The right light bounces back into the device onto a sensor
was hoping for more details about the laser and motor system
Good idea, we'll cover that in our next video!
wow so helpful. :)
So glad!

Yes

Thanks for sharing! I don't think a brief exposure like that would be bad, but it's always good to have an annual eye doctor exam to scan for problems

How does it see the code? Is it a camera?
The light bounces back into the sensor with the barcode info
how can you make a curved barcode scanner? So it scans 3 dimentional

How does the POS Machine read the barcode value
The barcode scanner we used was from Amazon. It imports the barcode value into an excel spreadsheet.
where does a scanner store the information on it, further how do groceries stores use it to check out their products
It's actually a PC!
