What is a QR Code?

A QR Code (Quick Response Code) is a two-dimensional barcode that encodes binary data into a square matrix using black-and-white markers. It was originally developed by the Japanese automotive industry to track automotive parts. There are 40 standard versions and 4 micro versions of QR codes. QR codes support four data encoding modes:

1. Numeric (Numeric): 0-9
2. Alphanumeric (Alphanumeric): 0-9, A-Z, space, $, %, *, +, -, ., /, :
3. Byte/Binary: Encoded according to the ISO/IEC 8859-1 standard
4. Japanese Kanji/Kana: Encoded according to the Shift JIS JIS X 0208 standard

QR codes have four error correction levels:

1. L (Low): Can correct up to 7% of the code
2. M (Medium): Can correct up to 15% of the code
3. Q (Quartile): Can correct up to 25% of the code
4. H (High): Can correct up to 30% of the code
