A QR Code (Quick Response Code) is a type of matrix barcode, or two-dimensional barcode, originally designed in 1994 for the automotive industry in Japan. Unlike standard one-dimensional barcodes that are read by a narrow beam of light, a QR code is detected by a 2-dimensional digital image sensor and then digitally analyzed by a programmed processor.
The capacity of a QR code is significantly higher than that of a traditional barcode. It can store up to 7,089 numeric characters or 4,296 alphanumeric characters. This flexibility is what makes WhatsApp QR codes so versatile for Send WhatsApp message.
For standard print materials like business cards, a QR code should be at least 2cm x 2cm. For larger signage, ensure scale matches viewing distance.
Maintain high contrast between foreground and background. Avoid placing dark codes on dark backgrounds or using light pastel colors.
QR codes include "Reed-Solomon Error Correction." Higher levels allow the code to remain scannable even if partially damaged.
