The IQR code works similarly to 2D codes like QR or Data Matrix, representing various data types, such as text, numbers, or binary data. Multiple layers and the complex structure of the IQR code ensure accuracy and reliability, even under challenging circumstances. Here are the components of the IQR symbol:

• Square modules
• Finder pattern
• Corner patterns
• Timing patterns
• Alignment patterns
• Quiet zone border

The layout and number of these patterns depend on the size and shape of the symbol.

Square modules are arranged in a regular square or rectangular array. These square modules contain the encoded data. The encoded data is represented in binary format, with black modules representing a binary 1 and white modules representing a binary 0. The finder pattern in the upper-left corner aids in accurate scanning regardless of the symbol's orientation. Corner patterns are placed in specific corners of the code, while the alignment pattern assists in re-synchronizing the decoding software if the code undergoes slight distortion. Timing patterns, consisting of alternating black and white modules in one row and column, determine the symbol's version and density. A quiet zone border surrounds the entire IQR code symbol. A quiet zone is a blank space or margin that separates the code from any surrounding text or graphics. It provides an explicit buffer zone to prevent interference with the scanning process and ensures reliable scanning and decoding.
