About This Use Case
Why Build a QR Code Scanner App in 2025?
With the global QR code market valued at over $13 billion in 2025 and growing at a rapid 17% annually (QR Insights), building a dedicated QR scanner and generator app is a strategic move. Over 2.2 billion people—nearly 30% of all smartphone users worldwide—now actively use QR codes for everything from payments to menu access.
Market Opportunity
The adoption of QR codes has exploded, particularly in the United States, where 99.5 million Americans are projected to scan QR codes in 2025 (LinkScan). The shift towards contactless interactions has cemented QR codes as a daily utility. Furthermore, the QR code payment sector alone is expected to reach $19.04 billion by 2025 (Market Research Future), highlighting the immense potential for apps that integrate scanning with wallet or commerce features.
