Great information about the QR code

Really helpful video

Thank You Sir

Can't imagine the mind who created QR codes

Is there a video using version 3?

Great❤

Hi! You are really good at this, and you moved me closer to some answers. But maybe because of my non well english i missed some important information. Whats the logic that you use to split qr to sectors? Because in my way i tried to decode QR by using your methodic (it was version 1 21x21 blocks). And i clearly know, that it starts from $ symbol (dec 36, 00100100 binary) but i cant get this combination even if i start from the bottom, what do i do wrong? I started to understand QR logic because i spotted some interesting QR from one company. He seems like regular one but have some hidden information inside. I used all scanners online and apps to decrypt it, but nothing works. For example when I am scanning it, it shows WT:1:40:102 and based on version 3 (29x blocks), but when Im generating my one, exact the same message converts to version 1 (21x blocks). And when they scan my generated QR it on their software it shows that nothing store inside, but if they scan their own with exact same text but based on version 3, showing hidden content inside.

For those wondering if the qr code in the video leads to somewhere. It doesn't

brooooooooooo best solution for Xnor gate hahahahahahahaha........

Weird question, but how do I recreate the error detection

I thought that I would find this video but it is cool

Thanks!

Once the readers can see more than 2 colours (black & white) we would be able to fit loads more data into a QR Code.

Thanks for the video, interesting! One qouestion: Is there a code that can be read in the 3 alignment squares? Or can they be read?

No. I don't think there is any readable information. They are there to help the QR code scanner locate and align the code, ensuring that it can be read correctly even if it is slightly distorted or rotated.

I know that, but if it where for them to be read, could they be read? they must be, only i do not know how! I wonder if there is any corelation to number 6. In the previous barcode, the three 6 were always present. It must be the same whith this one. For correct alignment one square only would have been enough.

Just want to say this first. I learned this topic specifically for this video. I am not an expert and this was made a while ago so I cannot answer you professionally. However, here I tried my best to give some assumptions. While a single alignment square might be enough, three squares provide more reliable alignment, especially qr code has more dimensions than a barcode. This also explain why larger qr code needs more small alignment square in the middle. Also, having three squares allows room for error correction even if one of the square is damaged. I don't think they directly contain readable information, but their spacing could theoretically be used for data encoding.

Sir I have a problem what I fill in E1,E2,E3,E4 etc plz help me

Is there any way to decode bigger QR Codes? :)

they are slightly more annoying, but certainly possible. For size 2 and up you have to skip over the alignment pattern, which makes your groups skewed and slightly more difficult to read. While for size 3 and up every group of 8 bits are alternating between the first half and the second half of the string. the wikipedia article on qr codes has a nice image of the pattern for version 3 and up. the idea is basically that the first four bits are the encoding type as usual, then the next four bits are the first half of the length, then you skip 8 bits and continue with the next four bits after that being the second half of the length and so you keep going, with each byte being four bits, skip eight, and then the other four bits, until you get to the end at which point you look at all the bits you skipped

Hi are you going to do any giveaways

Sexy 😄 By the way did you plot the qr in excel pixel by pixel or made use of some automation?

Thanks. I just plotted them pixel by pixel and some copy & paste because I am dumb. I think there should be better methods to do it.
