BrightMarker (invisible QR code technology)

2023: Product Announcement

On August 15, 2023, US researchers at the Massachusetts Institute of Technology (MIT) unveiled an invisible labeling technology called BrightMarker. This system can become an alternative to the usual bar codes and QR codes.

Experts say that QR codes, which were especially widespread during the COVID-19 pandemic, provide a quick and convenient transition to websites. Despite the widespread use of such tags, there are security risks. The fact is that cybercriminals can falsify a QR code by directing a user, for example, to a phishing page or site with malicious software. In addition, in some cases, QR codes can spoil the design of goods.

The BrightMarker system provides for the use of fluorescent labels that cannot be seen with the naked eye. An infrared camera is used to read them. The technology involves the creation of objects by 3D printing: at the production stage, fluorescent threads are woven into the product, so it is impossible to fake such a code. Scientists argue that such tags do not change the shape, functionality or appearance of the object.

The fluorescent composition emits light in the near infrared range: due to this, the marks are displayed with high contrast when viewed through infrared cameras. Researchers have developed two compact accessories for reading fluorescent codes: one of these gadgets can be connected to a regular smartphone, and the other to a virtual or augmented reality headset. Project participants claim that BrightMarkers can be used to track the history of certain products, verify the authenticity of products and for many other purposes.^[1]
