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.
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
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.
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!
BokanProductions To answer the question for anyone curious 2 years later here, the code will continue to be allocated to the product for awhile even after discontinuation ad many stores will still be selling the item for awhile, and many suppliers will still have leftover product for awhile. But in the long run yes it will eventually be recycled.
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?
Did they come up with the codes on the left side and then inverted them to get those on the right or are the codes on the left side an inversion of the codes on the right?
@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).
How do you make the translation from binary to decimal ? Left side the binary 0011001 is translated as 1, but on the right 1100110 is 1. I can see a logic in that on the right side the 1 becomes 0 and vice versa, but i can't see the further logic. I haven't been searching too much tbh. :)
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
but what about other barcodes... EAN-13 don't have the Modulo Check number or the Number System Character (0)... how do they work that stuff out... how do they do a final check?Also what is best practice, should we include the Check number and Number system in a barcode or should they not be part of the barcode...I guess you are using a UPC-A code, what is the difference between that and UPC-E?
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.

I think the prices are programmed into the system (the barcode reader device) and decided by whoever runs that local store. Some kind of manager or whoever. If the prices of the same product vary based on which store they're sold in, then printing the price right into the barcode might be inconvenient because if the store wants to change their prices they would have to the replace all of their products for having a wrong price in the barcode.
So does this mean that when a barcode is read wrong there is 1 in 10 chances of it being passed as correct? (as modulo check character is a single digit only)
No, you need to add or subtract 10 to your modulo calculation in order to perceive the same correct solution. This can only happen if multiple digits are read wrong, because the change of one number cannot result in a shift of 10 or a multiple from 10 (if 10 has to be added, you need at least two times an addition / subtraction, even with the multiplication of 3, because 10 is not dividable by 3). The chances of 2 digits being read wrong in such a way that it ads up to 10 is very much lower. And then we even ignore the fact that the chance of 2 digits being wrong-read is also about zero. So the check character provides a pretty accurate check. Furthermore, if such a "false-positive number shift" would happen, it wouldn't necessarily mean that the computer reads the bar code as correct, because if the read bar code is not in the computers database, it would still return an error. If you add this all up: the check character is accurate somewhere around 99.9% of the time.
Tell me if this idea could work or not. Could you go to a store, find a product for which you know coupons exist, take the manufacturer and product codes, and print out a coupon barcode (or enter the numbers of your code directly into the self-checkout)?
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'm pretty sure the instructions that the barcode provides are references to data already set inside the computer that makes sense of the numbers, because in the end the bits provide nothing but numbers that must be addresses already set in the memory. Now I'm not really sure if that's the way the computer makes sense of it, but I am sure that you can't install a virus. Now, unless you had a registry inside the computer which contains an infected file and you could open it by addressing it through the barcode (but this is another guess).
No. The program that reads the bar code can only read, check and write to the display of the computer. If you want to add a virus to the computer, you're gonna need access to the code of the program and change it. Reading a barcode won't do anything.
Timber Husky No. But, depending on the software and OS of the system, and how vulnerable it is, you could give it a specially crafted barcode that exploits a buffer overun and then executes shell code to give you superuser privileges.
I wish every educational video on youtube was like this. Brief yet comprehensive.

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!
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
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.
Way above my comprehension abilities. I got lost about a minute in and then my mind wanders about something I can comprehend.

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
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.

+dukestt What a deal!
dukestt. I saw that dude i was at Wal-Mart when I saw that
🤣😂🤣
i feel less dumb.
Same here;)
I'll never see barcodes the same way ever again. Thank you!
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
Amazing, I learnt this is 5 mins. Wow, great informative video.
Very nice and comprehensive way of giving a lesson. Thanks A LOT!
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
Absolutely fantastic! You make it seem so simple!
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.
It's important to note that this is a UPC, there are many types of barcodes and they work differently than UPCs
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.

Magnificent video tutorial. Very clear voice and wonderful illustrations. Thanks a lot :-) Subscribed.
It's unbelievable that all that happens in just one second when I beep my product in a store :0
very clear, short, yet enough info to understand barcode system. Great!
every answer to every question I had about barcodes right here!! thanx really helpful!!!
THEPROGOLDLION hey lol
When a product is discontinued do they reuse that product's barcode for a different product? I mean it's not like it's ever going to be used again.

You did this just in 4 minutes
Thank you
i work in a warehouse and im super glad to finally understand this
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?
@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?
Very elegant and clear presentation, thanks!!!
What's happens when it's completely scratched off is it still readable like able to read what barcode was there last?

Adrian Roata i think you convert the binary number based on the list in 1:40
not to decimal
I just spent the last hour trynna to figure out this x)
@@emad3241 Are those translations just completely arbitrary or is there some methodology which means that 0011001 = 1 etc?
What happens if u were to draw a line through the lines would it obstruct the processing of the barcode?
Go to your supermarket and find out!

Very good course to quickly understand how bar codes work.
Which program did you use to create this video ?
I need to do something similar for school and this would be exactly what I need....
This small video has everything and it was really easy to understand 😃
:( i wanted him to go into the tracking of items, very informative though! thanks!
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.

"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
Do we have to feed the manufacture and product codes in computer first?
but what about other barcodes... EAN-13 don't have the Modulo Check number or the Number System Character (0)... how do they work that stuff out... how do they do a final check?Also what is best practice, should we include the Check number and Number system in a barcode or should they not be part of the barcode...I guess you are using a UPC-A code, what is the difference between that and UPC-E?
Up to now, i’ve come to know how barcodes work. Really interesting information.
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
Thanks a lot because i have a presentation tomorrow on this topic.
This really helped me in my college math class. Thank you! :)
how
FABULOUS video!!!! Bravo. Request: Can you do a similar video for 2D Barcodes/QRCodes?
The people that came up with this were way ahead of their time.
Moooore video plz. This chanel could be in the top 10 edu channels on youtube!
Omg this is mindblown for me. Thank you very much! Old but gold video.
Is it work with ought numerical digit?
some barcode it seeing with numerical digit and some without digit!!
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.
Is the modulo check character similar to a checksum?
Holy crap. That was way more than I could have imagined.
Great job sir,thanks
i have learn how to make barcode, but i still dont know hot to set price on them !!!!????? if you kan help me with that
Is it possible to know the price of the thing that has this barcode on it ?
WOW!! I feel so enlightened!
You said that the first digit (in this case 0) shows the type of the product - so how about if the digit is 7?
1 - Reserved for future use
2 - Items sold by varying weight, such as meats and cheese.
3 - Drug and health items
4 - Used by stores for local needs
5 - Manufacturer coupons that can be doubled or tripled.
6 - General merchandise
*7 - General merchandise*
8 - Reserved for future use
9 - Manufacturer coupons that cannot be doubled or tripled.
It was a copy-paste so don't thank me about it.

Most efficient video on youtube
i feel much more clever now than i was when i woke up this morning
Very informative! Thanks a lot!
You are one damn good teacher man
Dude your videos are awesome!!
How does a store get their local price to be detected through the barcode?
I think the prices are programmed into the system (the barcode reader device) and decided by whoever runs that local store. Some kind of manager or whoever. If the prices of the same product vary based on which store they're sold in, then printing the price right into the barcode might be inconvenient because if the store wants to change their prices they would have to the replace all of their products for having a wrong price in the barcode.
thanks sir..Very easy n effectively explained..
I understood everything until the modulo check number and then I was like, "Yeah, I'll never be able to explain this to anyone..."
Great explanation. Why the channel stopped producing this type of videos?
That's help me understand and make my own DIY Barcode with MS-Excel, Thank you.

Im not sure those are differ or similar. But you can do googling and find it out. Bcuse i ever searched about it before.
Very well explained; thanks for sharing!
do you have any sources so i can use some of this info in a paper?
AWSOME !!! very very nice explainde!! keep it up man!!!
that was freaking awesome
So helpfull!!!!!! I always wanted to know how it works.
I can now read barcodes without a scanner, thanks!
