Since qr codes are based on placement of black and white sqaures, will we ever run out of qr codes?
Practically yes, you can create infinite qr codes.
The maximum capacity for a standard qr code (Wikipedia) is 2,953 bytes or 23,624 bits. Each bit has two states, so the number of possible permutations is 2^23624 or about 3.4*10^7111.
While this is finite number, but we definitely arent reaching that number. Therefore yes, we can create infinite qr codes.
Well if we believe Chris, we are almost out of QR Codes as it is almost 2025.
Jokes, a standard qr code A can have up to 177 rows and columns, which yields 31,329 different modules. And these modules have 2 possible states: black or white.
That means we can have 2^31,329 different combinations.
And if we ever reach these number, we can just add additional modules or squares to produce more original combinations
Thus, no we are not running out of qr codes.
