Yes, I learn much better when the audio randomly becomes super loud for less than a second & goes back to normal..Especially learn the best whenever he says anything with a 'b' or a 'p' sound & it explodes a deep thunderous 'puff' sound.
For anyone wondering , this is UPC-A barcode generation algorithm . There are many others , for example "Code 128" barcode generation algorithm is capable of encoding alphanumeric characters from ASCII character set.
Easily one of THE most informative videos per minute that I've seen! I learned more about bar codes in four minutes than I did in seventeen years in the grocery biz! Thanks!
I showed a photo of a paint can with a small bar code on it to an employee who scanned the screen and instantly brought up the same product on his phone. I work in a pretty tech industry and it's pretty cool that such a simple design works so well
It's funny, me and my dad were having a conversation about this when I was visiting him, and by chance I saw this video about 40 minutes before he phones, thanks a lot for the upload, this is a great channel.
Thats crazy the 0 and 1 light reflection was exactly the opposite of what I was thinking and this is all interesting. Definitely gonna dive deeper into this.
I might have missed it, but I think you forgot to mention that the numbers on the right side are inverted to those on the left (0 becomes 1 and vice versa). Zero on left: 0001101; Zero on right 1110010
Interestingly, I've noticed no one has pointed out that the right side's number codes are just the inverse of the left side's. Example: Left side 1: 0011001 Right side 1: 1100110
In the case of the barcode, the binaries are just a standard, not the binary equivalent for the decimal number. To convert a binary number to a decimal number you can use this: For example, converting 10101010 into decimal, 1*2^7+0*2^6+1*2^5+0*2^4+1*2^3+0*2^2+1*2^1+0*2^0 So the binary 10101010 is equivalent to the decimal 170.

@boombasticLee If you are attempting to calculate a 13th digit, then you are creating a symbology known as EAN13 (looks similar to UPC). In this particular example, UPCa takes 11 digits and produces a 12th (check digit).

The people who figured out this complicated system, what planet are they from? Whew! Excellent job with the video but I have to go now as my brain is now full! Best of luck!
Use Excel data to print bulk barcode labels - In order to improve work efficiency, you can first enter the value of the barcode in Excel, and then import it into our barcode generator software to make barcodes in batches.
Yep, but a computer does all that idying in a gazillionth of a second, so once the method is programmed with all it's triple security checks, the machine will do it for you at practically no cost and no time...

Especially if you are looking at the much compressed versions that define most of the equations by employing operators such as the gradient, divergence, curl or del operators. Then you have to look all of those up and learn that the bolded letters are actually Vector potentials or Vector fields, and how those function. Then you learn partial derivatives and cross and dot products. By then you will have just scratched the surface. Math, helping the universe confuse us.
That is only one of barcode types commonly used around, the EAN-13. Probably it is the most common one in Europe but even there it is not the only one. Americas have their own similar but not identical ways of doing the same thing. And that is only considering simple linear barcodes. Today 2D barcodes start to gain popularity especially in specific cases like airplane tickets and interactive ads. The video just barely scratches the surface of the whole barcode universe.
Love the way you have explained how barcode works. But how does one know exactly which manufacturer and product has which code? Is there an administered international database that we have to register into? Provided that there is no administered database, can anyone generate their own EAN barcodes for free, with their favorite numbers as manufacturer and product code?
QUESTION! ---- I'd really LOVE TO KNOW the extent of what a barcode can tell me --- I work in a warehouse & I've been told that the first 3 numbers tell you the country it was made in (true or not?), you mentioned the first digit showing standard or weighted things; what about 4 through 9? & do you know of a link or any reading material anywhere for me to look through? I've been looking on the web for ages but this video has told me more then all the other research I've done. Thank you!
The left and right guards only contains three bits "101" and both the left-side and right side code for the number six contain 7-bits, "0101111" and "1010000" respectively. Since "101" is not the same as "0101111" or "1010000" there is no 666. In the UPC code you must have all seven bits for a number to be recognized. Even if you treated "101" as a plain old binary number, it would be a five and not six. FYI, six looks like "110" in plain binary, and 666 would look like "1010011010".
I wish every educational video on youtube was like this. Brief yet comprehensive.
Perfect comment! If only they were!
Yes this channel is best

Finally! Now I can get rid of my POS system and read the bar codes myself!
ConnecticutEmporium Point of sale or piece of shit?
mxm m both, i guess
LOL I know this is a joke but you’d also have to memorize all of the manufacturing codes and the product numbers.
Finally! I know all the steps to shoplift!

Way above my comprehension abilities. I got lost about a minute in and then my mind wanders about something I can comprehend.
Wow, this was a great video. Very interesting and informative. Now I have a great conversation piece to break the awkward silence on a first date.
Lmao awesome
You're going to bore a date to death on the first date???
....and the last......😴
Hey girl wanna learn about barcodes lmao!! that would def be an ice breaker kinda funny too
HAHAHA
Walmart Employer: "So... what's a skill you have?"
Me: "I can understand barcodes."
🤣
LOL
hahahaha

These type of videos are what I always wanted! I wish the internet was more populated with this type of stuff. LOVE IT. KEEP MAKING MORE! And thanks.
Your voice should be on TV. Even when you say chicken soup it's interesting.
This cashier is grateful for the lesson!
Tobie Allen II same lmao
I'll never see barcodes the same way ever again. Thank you!
Concise and straight to the point! Thank you for making us learn and saving our time.
It's funny, me and my dad were having a conversation about this when I was visiting him, and by chance I saw this video about 40 minutes before he phones, thanks a lot for the upload, this is a great channel.
The most articulate explanation you can ever get in this world... Well done for Excellent videos.
Thats crazy the 0 and 1 light reflection was exactly the opposite of what I was thinking and this is all interesting. Definitely gonna dive deeper into this.
The people that came up with this were way ahead of their time.
i work in a warehouse and im super glad to finally understand this
It's important to note that this is a UPC, there are many types of barcodes and they work differently than UPCs
Very nicely done. I only wanted to know the basics of barcodes before I present a proposal to a company and it is well explained.
I might have missed it, but I think you forgot to mention that the numbers on the right side are inverted to those on the left (0 becomes 1 and vice versa). Zero on left: 0001101; Zero on right 1110010
Thanks a lot because i have a presentation tomorrow on this topic.
Amazing, I learnt this is 5 mins. Wow, great informative video.
Absolutely fantastic! You make it seem so simple!
very clear, short, yet enough info to understand barcode system. Great!
my scanner works on my phone, at least, and it really is Campbells Chicken Noodle soup. $1.29 apparently.
+dukestt What a deal!
dukestt. I saw that dude i was at Wal-Mart when I saw that
🤣😂🤣
Up to now, i’ve come to know how barcodes work. Really interesting information.
It's unbelievable that all that happens in just one second when I beep my product in a store :0
Great job sir,thanks
This is very useful lesson for me. Thanks to you I have made a project at my university!
Holy crap. That was way more than I could have imagined.
Very nice and comprehensive way of giving a lesson. Thanks A LOT!
You are really amazing
You did this just in 4 minutes
Thank you
"do you know how barcodes work?"
that would be a cool opener for that cute cashier :) LOL
I'm sure that cute cashier is on hour six of her shift and gives two fucks about how a bar code works lmao
Thanks a lot for such a brilliant lecture just in one lesson. Thanks again.
Interestingly, I've noticed no one has pointed out that the right side's number codes are just the inverse of the left side's.
Example:
Left side 1: 0011001
Right side 1: 1100110
every answer to every question I had about barcodes right here!! thanx really helpful!!!
THEPROGOLDLION hey lol
This really helped me in my college math class. Thank you! :)
how
In the case of the barcode, the binaries are just a standard, not the binary equivalent for the decimal number.
To convert a binary number to a decimal number you can use this:
For example, converting 10101010 into decimal,
1*2^7+0*2^6+1*2^5+0*2^4+1*2^3+0*2^2+1*2^1+0*2^0
So the binary 10101010 is equivalent to the decimal 170.
Maybe this can help you: watch?v=Fmb3TCvlETk
Omg this is mindblown for me. Thank you very much! Old but gold video.
Finally a video that answers my shower thought about a barcode knowing if it is upside down. Thanks lol
This small video has everything and it was really easy to understand 😃
Very good course to quickly understand how bar codes work.
My TaoHorse barcode scanner works great for 1D/2D barcodes, iPhone, PC, etc., finally know what happens, thanks:)
Very elegant and clear presentation, thanks!!!
Moooore video plz. This chanel could be in the top 10 edu channels on youtube!
Magnificent video tutorial. Very clear voice and wonderful illustrations. Thanks a lot :-) Subscribed.

that was awesome! exactly what i was looking for for the last 2 hrs! thanks for breaking it down for us!!
I'm replying to a 9 year old comment.XD
The people who figured out this complicated system, what planet are they from? Whew! Excellent job with the video but I have to go now as my brain is now full! Best of luck!
I can now read barcodes without a scanner, thanks!
@n40798
Yes, it is UPCA. UPCE takes in the same amount of data but produces an 8 digit barcode.
Thank you for this lesson. Can you share the presentation you used?
i feel much more clever now than i was when i woke up this morning
This is in Morse Code. It's dots and dashes to generate numbers.
Most efficient video on youtube
WOW!! I feel so enlightened!
Great explanation. Why the channel stopped producing this type of videos?
i feel less dumb.
Same here;)
Thank you so much. I was able to create a program to generate a barcode
Very informative! Thanks a lot!
I understood everything until the modulo check number and then I was like, "Yeah, I'll never be able to explain this to anyone..."
That's help me understand and make my own DIY Barcode with MS-Excel, Thank you.
Thanks 🙏🏻
You are one damn good teacher man
Use Excel data to print bulk barcode labels - In order to improve work efficiency, you can first enter the value of the barcode in Excel, and then import it into our barcode generator software to make barcodes in batches.
FABULOUS video!!!! Bravo. Request: Can you do a similar video for 2D Barcodes/QRCodes?
straight to the point good video
Dude your videos are awesome!!
This is one heck of a complicated way for identifying a product. We should make things more simple.
Yep, but a computer does all that idying in a gazillionth of a second, so once the method is programmed with all it's triple security checks, the machine will do it for you at practically no cost and no time...

The first 3 digits actually indicates the Country of Origin.
Very well explained; thanks for sharing!

Best amongst the best....Too Good
So helpfull!!!!!! I always wanted to know how it works.
Nice tutorial. Now when I work as a cashier and I can't see the numbers, I can just read the barcode with my eyes and write it by hand!
Thanks this lesson helped me alot.
Next time i see a tough guy with a barcode tattooed on the back of his head I'll be able to figure it out. It'll say Chicken Noodle Soup probably.
that was freaking awesome

Great videos hope to see more
Great source of information , in hardly 5 minutes
thanks sir..Very easy n effectively explained..
AWSOME !!! very very nice explainde!! keep it up man!!!
Quick and easy. Thanks
:( i wanted him to go into the tracking of items, very informative though! thanks!
You are awesome,
this is also 1 lession:
my-youtube-account + awesome lessions = subscribed
So theoretically, could I replace the type of barcode on lets say an apple from a 2 to a 0, and just get the apple without having to weigh it at all?
i never thought about the barcode needing an error check for being upside down- I’ve been a retail manager for 2 years
Thankyou so much for this amazing explanation :)
I searched up the bar code on the title screen on googly lens and it took me to Campbell's chicken noodle soup.
What's happens when it's completely scratched off is it still readable like able to read what barcode was there last?
wow what a fascinating video. kudos
so all this (over 4 minutes of explanation) happens at the split second bip of the check out! whoaahhhh!!!
I came here after I heard the song This is America, in the end of the song the guy says “we’re just a barcode”
