Type 1 (Model 1) is the most common type of QR code. It can store up to 4,296 alphanumeric characters, with a capacity of up to 2MB. Model 2 codes have the same storage capacity and size as Model 1, but there is additional flexibility for error-correcting levels. A micro or tiny QR code is often square in shape, making it significantly smaller than a model 1 code (which may be up to 10 centimeters in size). They can only hold up to 256 symbols, but they’re great for storing URLs or contact information. IQR codes are an even smaller version of the micro code and can only hold up to 16 symbols. SQRCs combine the greatest qualities of model 1 and micro codes into a single code that is small enough to fit in the subject line of a text message, or email yet has a vast storage capacity of 26 bytes.
