QRposting is a unique subgenre of internet culture where the humor is hidden behind a functional QR code. This trend gained traction as a way to rickroll unsuspecting users or to share hidden messages in plain sight on platforms like Twitter and Reddit. By transforming a utility into a comedic tool, QRposting challenges the viewer to engage with the content physically by scanning it with their smartphone. Whether the code leads to a niche image, a specific song, or a cryptic message, the meme relies on the curiosity of the digital audience and the tension between the physical and digital worlds. It has evolved from simple pranks into complex glitch art where the QR code patterns themselves are manipulated to resemble faces or iconic characters while remaining scannable.
