QR codes, or Quick Response codes, are two-dimensional barcodes developed in 1994 by Japanese company Denso Wave. These codes can store large amounts of information in a compact space and are readable by smartphones and dedicated QR code scanners. QR codes can contain various data types, including website URLs, contact details, and plain text.
They consist of black squares arranged on a white background, though they can be customized with different colors and designs. The functionality of QR codes relies on encoding information into a pattern of black and white squares that can be interpreted by a device’s camera. When scanned, the encoded data is extracted and can trigger various actions, such as opening a webpage, adding contact information to a phone, or initiating a payment.
QR codes are highly versatile and find applications in marketing, promotions, contactless payments, and accessing hidden content. The popularity of QR codes has grown due to their convenience and adaptability. They are commonly found on product packaging, business cards, posters, and in digital formats on websites and social media platforms.
The widespread adoption of smartphones has made QR codes an essential tool for businesses and individuals seeking to share information and engage with audiences in innovative ways.
