I was inspired to make this video based upon an explanation of barcodes I found in a great book called Code: The Hidden Language of Computer Hardware and Software amzn.to/pR9MwK . I highly recommend it.

I wish every educational video on youtube was like this. Brief yet comprehensive.
Perfect comment! If only they were!
Yes this channel is best
78u
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.
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!
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
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.
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!
Your voice should be on TV. Even when you say chicken soup it's interesting.
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
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.
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.
Absolutely fantastic! You make it seem so simple!
Very nice and comprehensive way of giving a lesson. Thanks A LOT!
This is very useful lesson for me. Thanks to you I have made a project at my university!
very clear, short, yet enough info to understand barcode system. Great!
Amazing, I learnt this is 5 mins. Wow, great informative video.
Thanks a lot for such a brilliant lecture just in one lesson. Thanks again.
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
every answer to every question I had about barcodes right here!! thanx really helpful!!!
THEPROGOLDLION hey lol
Omg this is mindblown for me. Thank you very much! Old but gold video.
Magnificent video tutorial. Very clear voice and wonderful illustrations. Thanks a lot :-) Subscribed.
WOW!! I feel so enlightened!
i work in a warehouse and im super glad to finally understand this
Very good course to quickly understand how bar codes work.
It's unbelievable that all that happens in just one second when I beep my product in a store :0
Very elegant and clear presentation, thanks!!!
Up to now, i’ve come to know how barcodes work. Really interesting information.
Thanks a lot because i have a presentation tomorrow on this topic.
This really helped me in my college math class. Thank you! :)
how
Thankyou so much for this amazing explanation :)
This small video has everything and it was really easy to understand 😃
I'll never see barcodes the same way ever again. Thank you!
That's help me understand and make my own DIY Barcode with MS-Excel, 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
You are really amazing
You did this just in 4 minutes
Thank you
Very well explained; thanks for sharing!
Thanks this lesson helped me alot.
Thank you for this lesson. Can you share the presentation you used?
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
🤣😂🤣
Very informative! Thanks a lot!
Thanks for the lesson.
Dude your videos are awesome!!
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
This is awesome. Thanks so much.
Holy crap. That was way more than I could have imagined.
great, concise explanation!
that was freaking awesome
Quick and easy. Thanks
Simply AWESOME!
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.
@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).
So helpfull!!!!!! I always wanted to know how it works.
Great job sir,thanks
@n40798
Yes, it is UPCA. UPCE takes in the same amount of data but produces an 8 digit barcode.
i feel less dumb.
Same here;)
Thank you so much. I was able to create a program to generate a barcode
straight to the point good video
Moooore video plz. This chanel could be in the top 10 edu channels on youtube!
Best amongst the best....Too Good
thanks sir..Very easy n effectively explained..
My TaoHorse barcode scanner works great for 1D/2D barcodes, iPhone, PC, etc., finally know what happens, thanks:)
Great videos hope to see more
That was great! Thank you
well done Sir. Thank you.
excellent...no words
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
Thank you very much ....
Thanks man for the video
AWSOME !!! very very nice explainde!! keep it up man!!!
You are one damn good teacher man
Great explanation. Why the channel stopped producing this type of videos?
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.
neat and perfect!!!!
wow what a fascinating video. kudos
What a fantastic video! :D
Really very useful Thank u
What's happens when it's completely scratched off is it still readable like able to read what barcode was there last?
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
Very good job.
Finally a video that answers my shower thought about a barcode knowing if it is upside down. Thanks lol
Fantastic!
very well explained
nice work Sir
Thank You!
crazy stuff, thanks!
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?
You are awesome,
this is also 1 lession:
my-youtube-account + awesome lessions = subscribed
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?
Great video!
Interesting and informative video, thanks (y)
thnxx really very helpful for me ;)
superb..
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!
Do we have to feed the manufacture and product codes in computer first?
Thanks for that!
This is an amazing video 😍
