What Qr and blank code let any piece or print host a link to online communication?

QR codes and NFC (Near Field Communication) tags can both serve as links to online communication. QR codes are scannable images that, when scanned by a smartphone camera, redirect users to a specific URL or online resource. Similarly, NFC tags can be embedded in physical objects and, when tapped by a compatible device, can initiate a link to a website or app. Both technologies facilitate seamless access to digital content from physical items, enhancing user engagement.
