You know you've reached the bottom of the boredom barrel when you're sitting around reading barcodes.

Me: That's a lot of math, I don't think anyone can.. *Beep*

1:17 Him: Got it? Me: No. Him: Good.

1:36 The pattern I saw was that the right bars are negative to the left bars.

That smooth transition to the sponsorship

This whole series can be used as a study on how to make effective sponsorship transitions!

I can’t believe the U.S. didn’t make their own versions of barcodes.

0:29 Notice how the building are smudgy? It's because it isn't a drone shot, rather a google earth capture.

Dat sponsorship transition tho

So now i can read barcodes but can't understand it

4:01 my favorite quote "easy right? , at least if you'r a machine"

0:34 it’s pronounced Can-bruh.

Expect a call from your mother after she sees the sorry state of your fridge.

This wasn't half as interesting, I found this fully interesting imo

Half as interesting: you might see a pattern Me: 👁️👄👁️

Instructions unclear, Agent 47 still strangled me.

I knew barcodes were technically a font, but I didn't know that there was an organization of barcode overlords haha. great video!

Is it me or every cool KZfaq channel is now sponsored by Squarespace?

Anyone else feel uncomfortable about the way he said Canberra?

I stumbled onto your channel today and I’ve been binge watching your videos and find them VERY interesting. Never thought I’d be watching a video explaining bar codes but here I am. 👍🏼

You should really distinguish between a barcode and a UPC (Universal product Code). What you described is a UPC, a type of barcode. There are many types of barcodes which are not UPCs, kind of like the way a square is a rectangle, but not all rectangles are squares. Some can be read from any direction, some can't, some are 2D and hold lots of information. Most types of barcodes do not need to be licensed to be used. I think it's really confusing to most viewers to imply that all barcodes work this way, or are organized in this fashion. There is also the matter of country code 4, which is reserved for "local" use and can be used by anyone without licensing. This is often used for things such as store loyalty cards.

what's the barcode number for an airbus A380?

you are a real smooth operator with those slick transitions from your content to the sponsors message. kudos!

This isn't for barcodes in general, just for UPC-A codes which are the most common you see in store products. A more compact UPC-E is a smaller barcode is also common with only 6 digits encoded instead of 12. You see them on things like soft drinks and candy bars. These are basically a shorthand for certain 12-digit codes (ones with lots of zeros) and can be converted back into the full 12-digit code.

Next - Qr codes

This channel should really be renamed "Twice as Interesting" !!!

These videos are amazing. I wish they were longer!

0:33 wow as a Canberran this is probably the most recognition we will ever get

The right hand section isn't just odd numbered it's the inverse bar pattern. So the code for each number is the same, just swap white for black on the opposite side.

Like half of the comments are about the absence of planes in this video.

Whenever I see a great joke, intersting video or a smooth transition to and add, I know I must like

Loving the new channel dude! Twice as interesting 😏

Two videos without planes! Wow!

I’m pretty sure you missed out on how the first digit is depicted in the code. There is not just one set of patterns for the left side, there are two. And the order of those digit patterns on the left side „implicates“ the value of the first digit. That‘s why you only need to code twelve digits (95 bars = 3+5+3+7*12) although there are 13 digits in the code (therefore its name EAN-13)

The attention to detail of that actually being the Tesco in Thurso is great 🙌🏻

Every time I watch some old random Sam's video I get amazed how he improved as a narrator. Fantastic

Video Suggestion: Timezones and Daylight savings time. How and why did it start, and what effect did it have on people or the economy?

You should have explained it better that not every barcode is the same. Just like you have the Baseball "World Series" where only North American teams compete, the American barcode system is called UPC = Universal Product Code. Except that it also only covers small part of the worlds. The actual global system is the EAN = European Article Number which has 13 digits where the UPC has only 12. Then there is the ISBN = International Standard Book Number which has 10 digits which can be converted to an EAN by removing the last digit (the ISBN check digit), adding 978 for "book land" at the beginning and calculating the EAN check digit. ISBN 1408855658 becomes EAN 9781408855652.

Critiquing, not criticizing. This is only one type of barcode, albeit, the most recognizable. This is EAN-13 (International Article Number). What we typically see in the US is UPC-A, a subset of EAN-13. There are other formats (e.g c128) that aren't regulated by any organization, and that are encoded differently. QR codes are technically a 2d barcode, and encoding is very different. For the codes discussed in the video... The middle 3 bars (the middle guard) is actually 5 bars long.. white, black, white, black, white. The left side of the code is technically 6 digits long, but only has space for 5 characters. The 6th digit is encoded. There are two sets of numbers for the left side (set G and set L). Depending on on what the first digit of the code is, the L/G pattern changes. I.e LLLLL is 0, LGLGLG is a different number, etc... Thus, the black/white pattern for each number isn't always the same on the left side of the barcode. The check digit is normally called the checksum and calculating it is a bit different than described. You add the odd digit positions and multiply by three, add the sum of the even digits to the result of the odd digits, store that number as x, round to the next number divisible by 10 (which l will call y), then calculate y-x. This is your checksum. The right hand side of the barcode isn't necessarily odd white spaces. It's actually the inverse of the L patterns mentioned earlier.. and happens to be odd 😂

Do one on airport designs

Can-bra, God damn it! It's Can-bra!

This is how my friends teach me something Basically.

4:09 is literally the best ad transition I've ever seen on a video, lol!

Shout out to Tesco

How to read QR codes please!

I shop at Coles in Canberra. That just made my day. Of all the stores on Earth you could've said, you said the one I shop at.

Got it? Me: no Good. Me: Erm

Clicked so fast I broke the sound barrier

CanbeRRa smh

hai + baumgautner art restoration: smooth ass ad transitions that feel nice

Thank you for this video. Ever since I worked in retail I wanted a barcode video. I think they are simple genius!

This was hilarious as it was informative. Keep rocking on, Half as Interesting!

In Australia we tend to get really pissy about how foreigners pronounce our city names. Canberra: Can-bra Melbourne: Mel-bin Brisbane: Briz-ben/Briz-bin Cairns: Cans Yes it's awkward but it how we say it

Very interesting. I've done work involving barcode scanning, and have recently been given a scanner. I'm going to be checking stuff out now.

A lot of thought went into this. I like it

This was a really informative video, and so wonderfully written so anyone can understand! I’m actually gonna check barcodes now when I go shopping to see if I notice company codes!

What about ambiguity? For the sake of simplicity and explanation let's say these barcodes had 4 digits. How do you differentiate between a barcode with company code 59 and product code 39, and another barcode with company code 593 and product code 9? :/

I don't normally watch the sponsored bits but that was smooth well played

I work in a meat room at a grocery store and the barcode system there is a lot different than how it works in other places, according to your video. Most of the numbers on the barcode are taken up by the PLU for the meat and the price. Say the barcode is 2 04009 91366 3: The 4009 is the PLU for that particular cut of meat. A small pack of porkchops might be 4010; a chuck eye, 3030. I have no idea what PLU is or what it stands for, but it's the code we put into the computer to tell it what it is we're making a label for. They also exist for produce and some grocery items (especially ones that are difficult to scan, like bags of road salt or ice). I can only assume that the first "0" before the PLU is kept blank in case of a 5-digit PLU, though I could be wrong. The 1366 is the price; in this case, $13.66. I have no idea what the other numbers mean in this system; any insight would be appreciated.

Thank you! Very easy and engaging! What's the next week video? QR codes? 😂

Very smooth ad transition

it’s crazy that there’s so much thought put into something as normal as a barcode and the people doing it are making big time money from it

That transition was so smooth I almost didn't realize it was a sponsor.

622 code isn't Switzerland. It's Egypt. Switzerland is 760 to 769

Thanks for the awesome videos! I think you may have misrepresented the check digit in this video: During the summing of the digits to be multiplied by 3, you show 3, 0, 7, 4, and 6, but according to GS1, the numbers to be multiplied by 3 are 2, 2, 0, 3 (because of the central and non-enumerated digit being an even entry), 7, and 6; which coincidentally add up to 20 as well. This caught my eye when watching the video and figured you'd want to be sure you're accurate. Thanks again! And keep up the awesome work!

*that smooth transition to square space*

I've looked this up before, and all I could find was how to read UPCs (the numeric code under the bars). I finally came across this video showing the actual bar code instead of the UPC.

That transition though at the end... Jokes on you I self taught myself to code and for free 😎

A lot of things suddenly makes sense to me. I hereby proclaim myself Master Checkout Lord

Okay I just took the nearest product from me and the barcode ends with ">" WTF

2:12 yoo my mans on the KZfaq diet 😭 got bless you bro 🙏🏻

what i fully understand from those five minutes is that i need to buy a squarespace account, because it just works. not my fault, my brain's barcode is only 1 digit

What about barcodes that have a secondary barcode after the primary one, that typically denotes the price? Where do those barcodes fit in with the rest of the GS1 codes?

That has got to be one of the best segways I’ve seen in a while

Hey that was the smoothest ad transition yet!

I immediately tried the check digit verification out on product close at hand, and I couldn't do it. I researched and found out that it's because how you calculated your check digit is wrong... Though, funny enough, it still works for that particular barcode either way. When you said the add the odd digits, you added the second chunk digits together; however, you were supposed to add the odd sequence placement digits: ie, 6+2+1+3+7+6=25. Multiply that by 3 to get 75 then add the even spacing digits: ie, 2+2+0+0+4=8. Take both numbers and add them to get 83. Subtract that from the equal or *higher* value of ten to get your check digit value.

The transition to squarespace was so smooth, i almost thought it had something to do with barcodes

I noticed that, for the same digit, that the white spaces on the left are at the same place as the black spaces on the right. Also YOUR VIDEOS ARE AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I learn something new each time.

I learned something about the complexity of the system AND why it works worldwide...for me it was worth 5 minutes of my life to listen...spend an hour a day getting news & random bits of knowledge...I might or might not ever use...

Where the planes at?

Me: "sounds like wendover, but can't be, right?" *checks description* Knew it!

Amazing transition!

I can't go anywhere without hearing about Squarespace, skill share, Brilliant or Hover. I even started playing a game of guess which sponsor it is

That transition into the squarespace sponsorship was so good at the end

So what does this have to do with planes?

At work, I discovered our terminals have various barcode formats installed as system fonts (e.g. each glyph in the font's character set maps to a certain encoding) so I actually set up some formulas into an Excel spreadsheet where I can type in an arbitrary UPC number and get the corresponding UPC barcode. WHICH ACTUALLY SCANS. (This wasn't just a nerd exercise: we have one customer who periodically orders a large number of items at a time, often the same items, so printing out a list of them with scannable barcodes instead of just the UPC numbers saves me the time of actually locating each item to physically scan, or typing in UPC numbers by hand)

Useful information Thanks for sharing

i never knew how barcodes work all i knew was "they scan them and they know what it is"

That advertisement transition was sly AF Good vid btw

I feel such a genius right now 😎 this is awesome content keep up the good work

I gave a like for how smoothly you transfered into the squarespace add 😝

Interesting! Top tip. When pronouncing an Australian word, especially an Aborigional word, leave out any hard sounds within the word. CAN-bara, not CAN-BEAR-a. Same with places like Toowoomba, Wagga Wagga or Onkaparinga, all having soft sounds

Thank you I can finally read Agent 47's barcode.

HAI is known for its smooth transition to ad.

Dat SMOOTH advertising at the end tho.

I came here to learn how to read barcodes. All I learned here was about formatting and not actually how to translate the numbers at the bottom of a barcode into the number the barcode scanner reads, which is different.

Girl: come over. HAI: I can't, I'm busy. Girl: I need someone to teach me about international standards and the companies that regulate them. HAI: I'll be there in 5.

i always wondered about these bar codes ..thanks

Good info, especially the country code
