QR Code Resources
QR codes have moved from a niche technology used in logistics and manufacturing to a ubiquitous part of daily life across Asia and globally. Singapore hawker centres display QR codes for cashless payment. Malaysian businesses used them for safe entry during the pandemic. Restaurants worldwide replaced physical menus with QR code links. Understanding how QR codes work and how to create effective ones has become a practical skill for anyone running a business, managing events, or working in marketing.
The articles on this blog cover the practical questions people actually have about QR codes: how to scan them on older phones, whether they expire, what size to print them at for different surfaces, how to link a QR code to your Google Business profile for reviews, and how to customise them with colors and logos while keeping them scannable. Each article connects to the free QR code generators on this site where you can immediately create what you need.
All QR codes generated here are static codes created entirely in your browser. Unlike dynamic QR codes that require a paid subscription service to function, static QR codes encode data directly in the image and work forever with no ongoing cost. The tradeoff is that the destination cannot be changed after creation - but for most use cases like restaurant menus, business cards, and WiFi sharing, this is not a limitation that affects day-to-day use.
