A standard QR code is identifiable based on six components: Quiet Zone - This is the empty white border around the outside of a QR code.
Without this border, a QR reader will not be able to determine what is and is not contained within the QR code due to interference from outside elements. Finder pattern - QR codes usually contain three black squares in the bottom left, top left, and top right corners. These squares tell a QR reader that it is looking at a QR code and where the outside boundaries of the code lie.
Alignment pattern - This is another smaller square contained somewhere near the bottom right corner. It ensures that the QR code can be read, even if it is skewed or at an angle. Timing pattern - This is an L-shaped line that runs between the three squares in the finder pattern. The timing pattern helps the reader identify individual squares within the whole code and makes it possible for a damaged QR code to be read. Version information - This is a small field of information contained near the top—right finder pattern cell.
Data cells - The rest of the QR code communicates the actual information, i. Numeric mode - This is for decimal digits 0 through 9. Numeric mode is the most effective storage mode, with up to 7, characters available. It allows up to 4, characters to be stored. Byte mode- This is for characters from the ISO——1 character set. It allows 2, characters to be stored. Kanji mode - This is for double—byte characters from the Shift JIS character set and used to encode characters in Japanese.
This is the original mode, first developed by Denso Wave. However, it has since become the least effective, with only 1, characters available for storage. However, some newer QR code readers will not be able to read this character set. There are two additional modes which are modifications of the other types: Structured Append mode - This encodes data across multiple QR codes, allowing up to 16 QR codes to be read simultaneously.
