A QR code
(quick-response code) is a type of two-dimensional matrix
barcode. It was invented in 1994 by the Japanese company Denso
Wave for labeling automobile parts.
Here are some key points about QR codes:
Design and
Structure:
A QR code consists of black squares arranged in a square grid on
a white background.
It includes fiducial markers that help imaging devices (such as
cameras) read and interpret the code.
Unlike traditional barcodes, which are linear, QR codes are
two-dimensional, allowing them to store more information.
Data Encoding
Modes:
QR codes use four standardized modes of encoding:
Numeric: For encoding numeric characters (e.g., phone numbers).
Alphanumeric: For letters and numbers (e.g., URLs or text).
Byte or Binary: For encoding binary data (e.g., images or
files).
Kanji: Specifically for Japanese logograms (characters).
Applications:
Originally used for tracking automobile parts, QR codes have
expanded to various applications:
Product Tracking: Faster reading and greater data storage
capacity.
Item Identification: Replacing individual bar-code labels.
Time Tracking: Used in document management and logistics.
General Marketing: QR codes can link to websites, vCards,
emails, and more.
Scanning QR
Codes:
Most modern smartphones have built-in QR code readers in their
camera apps.
You can scan QR codes to:
Open webpages.
Add contacts (vCards).
Connect to Wi-Fi networks.
Compose emails or text messages. |
