You start by describing UPC-12 but the country codes only appear in EAN-13.

wow. that is the most confusing explanation of number to bar code conversion that i've ever seen in my life! it was easier figuring out the pattern myself 20 years ago. back then, i worked as a cashier at a grocery store. when i was bored waiting one day, i decided that i wanted to figure out how bar code numbers were encoded. so i did. the difference between left and right numbers is so much simpler that this video explains. and not mentioned at all in this video is that every digit can essentially be written in reverse order. every digit has 2 bars and 2 spaces. the width of each bar and space can be anywhere from one unit width to 4 units wide. and an entire 'digit' of 2 bars and 2 spaces always use 7 units of width. so how many ways can we add 4 numbers to total a width of 7? there are 20 ways to add 4 digits to 7, which gives us 20 ways, with 10 digits and a revers way for each digit: 1+1+2+3 or 3+2+1+1, (both mean digit 0) 2+2+2+1 or 1+2+2+2, (both mean digit 1) 2+1+2+2 or 2+2+1+2, (both mean digit 2) 1+4+1+1 or 1+1+4+1, (both mean digit 3) 1+1+3+2 or 2+3+1+1, (both mean digit 4) 1+2+3+1 or 1+3+2+1, (both mean digit 5) 1+1+1+4 or 4+1+1+1, (both mean digit 6) 1+3+1+2 or 2+1+3+1, (both mean digit 7) 1+2+1+3 or 3+1+2+1, (both mean digit 8) 3+1+1+2 or 2+1+1+3, (both mean digit 9) The 1st way shown is the 'normal' (forward?) way. The 2nd way shown above is the 'reverse' way. (Notice the order of numbers are reversed.) These numbers are how many units wide each bar or space is for the alternating bars and spaces for that digit. Note that for all widths, on the left half of a grocery barcode, the widths represent bar widths that are white, black, white, black. And for the right half of the bar code, the colors are black, white, black, white for each digit. There is a black, white, black bar pattern between the left and right sides. So when this video shows the patterns, because it's overlaid on a white background, it's impossible to determine these specifics from the video. (I just looked at 3 bar codes for my list i just made.) For most groceries, only the forward way is used, that is, 1+1+1+4 for digit 6, not 4+1+1+1. But i have noticed that in some cases (like short bar codes [small products]), some of the digits are reversed, and which digits are reversed follow a common pattern too. Books (in the USA) also have an ISBN number that uses this same bar code encoding except there is an extra prefixed short bar code beside the normal bar code. And some digits on the ISBN bar code are reversed and it always seems to be the same digits. Well, that's what i noticed when i played around with reading bar codes. ;P

That was the most interesting thing I've learned today, srsly nowadays everything is becoming more and more complicated and un intuitive, theres so much cryptic bullshit floating around us that we can't even imagine how fucked we all really are, likeis electrosmog a thing, where is my data saved, who saves my data, why is there is no fucking apocalypse out there and everybody is driving cars when in fact we are like a decade late for deadline to a final solution to the oil alternatives, the world wide apocalypse that should have happened in like 2008 or so that we should all have died from long time ago... I mean we are still alive because reasons, but we don't really know when it really happens and even if it really happens. Just an example... Anyways, understanding the logic behind crap like bar code, like shit I thought to be unimaginable electro wizard fuckery I could never understand, gives me back at least some sanity. Thanks mate!
Its not can-beara, it's canbrrrrra

Cool advice: if you read "italian food" somewhere, check if the barcode is 80. If it's not, it's fake (spoiler alert: almost 99% of supposed italian food abroad is fake)

0:34 UGGHHH!! Why is it so hard for people to look up the correct pronunciation for Australian places?!? It's "Can-bra". "Can-bra". Not "Can-bear-a", or "Can-bar-a" or anything like that. "Can". "Bra". Simple!

Amazing video. However at around 4:00 when describing how to calculate the check digit, you stated that the multiple of 10 closest to 73 was 80! Regardless, very informative video. Keep up the good work.

I really think that this was a great video, because it taught me very much about how the barcodes are set, programmed and eventually read by the scanning machines. But what's also great is that you can get 10% off at the Squarespace platform where you can easily build your own website by using their beautiful templates.

Let B={x_1,x_2,x_3…x_12 },where x_1,x_2,x_3…x_12 are the digits of the barcode in left to right order. So,the check digit (ie x_12 )=10(⌈(3(∑_(i=1)^5 x_2i )+∑_(i=1)^6 x_(2i-1) )/10⌉)-(3(∑_(i=1)^5 x_2i )+∑_(i=1)^6 x_(2i-1) ) So plug in the digits, and you will be good.

The code for six on the right is exactly the same as the dividers - i.e. 666. It's a fact. The last book of the Bible foretold 2000 years ago that in the last days we wouldn't be able to buy or sell without the mark of the beast and his number, 666. There is also a third set of numbers which can be randomly used to replace lines on the right to obfiscate the fact of the six bar. The owo didn't want the public to work it out but a man named John was given the code in a dream in 1984.

this is the funniest thing u said there are 95 bars and then u said where the 9 always are but the u said the remaining 84 when there are actually 86 remaining

Are barcodes being recycled also?
Mike Corleone (3 months ago)
They just skip over the fact that the three at the front, middle, and end that divide them are all 6's. (666)
AnantaSesaDas (3 months ago)
More simply put is that the number of WHITE spaces on the LEFT is exactly the number of BLACK spaces on the RIGHT. They are just inverted. Much easier. And every digit uses 2 black bars regardless of space width.
