QR stands for Quick Response, explaining the main reason for QR codes – very fast readability. QR codes can store more information than traditional barcodes. They can contain numbers, letters, binary data, and even Japanese Kanji characters.
QR codes use a multi-level error correction system. Even if part of the code is damaged, it can still be decoded. The levels are L (7%), M (15%), Q (25%), and H (30%) of the code area.
The code contains fixed zones with information about the version, format, and data type. Three prominent finder patterns help with orientation, while the rest contains the data mixed with the error correction key. Data types include contact info, calendar events, emails, phone numbers, GPS coordinates, Wi-Fi credentials, and URLs.
