How BARCODES Work

Barcodes In One Lesson. Barcodes have revolutionized modern life. Discover what happens every time you hear a beep at the checkout.
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.

[@PacoOtis]

Perfect comment! If only they were!

[@aaryashukla8404]

Yes this channel is best

[@paulshevyakov4542]

78u

[@LeonSheeter]

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.

[@ConnecticutEmporium]

Finally! Now I can get rid of my POS system and read the bar codes myself!

[@mxmm744]

ConnecticutEmporium Point of sale or piece of shit?

[@m0llux]

mxm m both, i guess

[@melodysm]

LOL I know this is a joke but you’d also have to memorize all of the manufacturing codes and the product numbers.

[@moneybandzzzz4352]

Finally! I know all the steps to shoplift!

[@fdgxtgtybfgvg1086]

Walmart Employer: "So... what's a skill you have?" Me: "I can understand barcodes."

[@vasistamahadev]

[@MrJerzy624]

[@abdelrahmanmagdy298]

HAHAHA

[@niktwister]

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.

[@LMBee00]

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

[@DenizDales]

Your voice should be on TV. Even when you say chicken soup it's interesting.

[@foadrightnow5725]

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!

[@Danielmountford_]

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

[@pinche1994]

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.

[@arturshchukin2341]

Concise and straight to the point! Thank you for making us learn and saving our time.

[@TRAVELLEROFWORLDS]

This cashier is grateful for the lesson!

[@lolgerman]

[@OliverBack]

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.

[@mouadsifessalam]

Great videos hope to see more

[@deathby1hpgaming485]

The people that came up with this were way ahead of their time.

[@mark0nius]

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

[@DaElfer]

Thank you so much. I was able to create a program to generate a barcode

[@alhdlakhfdqw]

AWSOME !!! very very nice explainde!! keep it up man!!!

[@Poornima_life]

[@3ds12Game]

You are awesome, this is also 1 lession: my-youtube-account + awesome lessions = subscribed

[@EarlWallaceNYC]

Quick and easy. Thanks

[@Drevilbreakfast]

straight to the point good video

[@IDAutomation]

@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).

[@joni4757]

Interesting and informative video, thanks (y)

[@xerox844]

You are one damn good teacher man

[@oceantrolls73]

well done Sir. Thank you.

[@umargul5644]

Great job sir,thanks

[@AmDsus2Fmaj7Am]

"do you know how barcodes work?" that would be a cool opener for that cute cashier :) LOL

[@Dee-df3mo]

I'm sure that cute cashier is on hour six of her shift and gives two fucks about how a bar code works lmao

[@IDAutomation]

@n40798 Yes, it is UPCA. UPCE takes in the same amount of data but produces an 8 digit barcode.

[@CrabMinded]

Moooore video plz. This chanel could be in the top 10 edu channels on youtube!

[@carlziade4353]

Thank you for this lesson. Can you share the presentation you used?

[@james77011]

This is an amazing video 😍

[@LinoJustin]

Thanks man for the video

[@appoline2327]

My TaoHorse barcode scanner works great for 1D/2D barcodes, iPhone, PC, etc., finally know what happens, thanks:)

[@deepaklokare]

Really very useful Thank u

[@craigmichael19]

crazy stuff, thanks!

[@hideokuwaki]

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

[@jlemus6976]

[@mahbubahaque3506]

very well explained

[@mattG527]

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!
