I'm going to teach you how to read QR codes, those ones that look like have random scattered dots. But remember, decoding QR codes requires the knowledge of reading Binary. If you don't know how to read Binary, please read this thread: gdforum.freeforums.net/thread/8327/p1kachu-presents-binaryToday, we will try to decode this: We will mark each black bit by 1, and each white bit by 0.
First step is, you need to know the mask of the QR code. You need to look at these 5 bits first: This 5 bits are 11101. We need to XOR this by 10101. Yes, every QR code XORs by 10101. Therefore, we get: 11101 1010101000 We only need the last 3 bits, which is 000. Therefore, our mask here is "000". Using the chart below: We see that Mask 000 is a checkboard. Which leads us to the next step.
Before we use the mask, we must first determine the useless bits, which are shown in red: Now to remove them: Now, the mask bits are shown in blue: Then apply them by XOR the blue bits: (Sorry if it looks somewhat messy and distorted ) Which leads us to our next step.
Starting from the lower-right corner, we must move as a zigzag motion as follows: Left Up-Right Left Up-Right... Then when you reach a top side, it becomes: Left Down-Right Left Down-Right... So if we read it, it becomes: 010000000111... Every QR code starts with 0100. The next 8 bits shows us how many characters there are. So: 00000111 = 7 characters. Therefore, we only need to get the next 56 bits. Which are: 01010000011010010110101101100001011000110110100001110101 The last step is to convert this to text. It reads "Pikachu"
Therefore, the QR code, when decoded, gives Pikachu! Thank you for reading, I hope this helped.

I do that sometimes... you my friend... have no life. I took computing in college yet we dont have to know what a qr code means (yeah we have to know how they work, but not how to read them :S)

How much IT do you even know??? I barely just got into IP-Adressing and IPV6... I kinda hope you can't do Hex, so i feel a little bit special ;3;
