QR Code / Development Terms QR Code A QR code (Quick Response code) is a two-dimensional barcode that stores data and can be scanned using a smartphone or QR reader. When scanned, it directs users to digital content such as a website, contact information, a download link or a payment portal. QR codes provide a quick and convenient way to bridge offline and online experiences, especially in mobile-first environments. These codes are commonly used in marketing materials, product packaging, signage and event promotions. For example, a nonprofit might place a QR code on a flyer that links to a donation form, while a SaaS company could use one on a trade show booth to direct attendees to a product demo. QR codes are highly adaptable, easy to generate and can be customised with logos, colours and frames to match a brand’s visual identity. QR codes offer a contactless, efficient way to engage users and track offline campaign performance. When paired with analytics tools, they can reveal user behaviour, scan locations and conversion data. For B2B and SaaS companies, QR codes support lead capture, onboarding and customer support flows. For nonprofits, they help increase donor conversions, distribute resources and streamline event check-ins. Best practices include placing QR codes in visible locations, using high-contrast designs and providing clear calls to action to encourage scanning.
