Why did QR codes become popular after COVID?|COVID created an overnight need for contactless menus and payment systems. QR codes were already built into every modern smartphone with no app download required, making them the fastest and cheapest deployable contactless solution. US scans grew 94 percent in 2020 and the behavior has not reversed. When did QR codes become mainstream in the US?|QR codes reached mainstream adoption in 2020 during the COVID-19 pandemic. Prior to 2020, roughly 12 percent of US smartphone users had scanned a QR code. By 2021 that number had reached 52 percent, and by 2023 approximately 89 million Americans were active QR code users. Are QR codes still popular after COVID?|Yes. The behavioral familiarity built during COVID has not reversed. Businesses that built QR code infrastructure have kept it. Native camera-based QR reading is a standard smartphone feature. Scan volume has grown every year since 2020. What comes after QR codes?|The next evolution is not a replacement for QR codes but an addition to them — talking QR codes that play an AI voice message when scanned rather than silently redirecting to a webpage. The scan is identical. The outcome is a voice interaction rather than a silent link. Available at TalkingQRCodes.com.
