What commenters say

  • The QR code's ability to send users to different destinations based on the angle of view could be used to create interesting and dynamic experiences, such as scavenger hunts or magic tricks.
  • The technology has potential security implications, as it could be used to manipulate users into visiting malicious websites or revealing sensitive information.
  • Some argue that the benefits of this technology are outweighed by the potential risks, and that similar effects could be achieved through more conventional means, such as server-side redirects.
  • Others propose that the ability to manipulate QR codes could be used for targeted attacks, such as phishing or social engineering, by creating codes that appear legitimate but redirect to malicious sites.
  • The use of lenticular design in QR codes could also be used to create physical attacks, such as replacing legitimate codes with malicious ones, or creating codes that change behavior based on environmental factors.
  • There is disagreement over the practicality and effectiveness of using this technology for malicious purposes, with some arguing that it would be too complex or noticeable to be useful.
  • The fact that different devices and platforms parse the QR code differently could be exploited to create attacks that are specific to certain devices or environments.
  • The potential for abuse of this technology highlights the need for increased awareness and education about QR code security and the potential risks associated with using them.
