15.4.2 QR Code Model 2 versions and data capacity
Each QR Code Model 2 version can encode a maximum amount of data (numeric,
alphanumeric, byte, Kanji).
QR Code has error correction capability to restore data if the code is dirty or damaged. Four
selectable levels of error correction are available: L (7%), M (15%), Q (25%) and H (30%).
This means if for example error correction level H (30%) is selected, the code can be read
even if up to 30% of the code is damaged.
The numbers in the table indicate the maximum number of characters that can be encoded.
The QR Code Model 2 versions that are indicated with 299 characters in the following table,
are capable of storing more characters. However, 299 is the maximum number of characters
that can be entered with the laser marking system.
