Physicists at TU Dresden write, read and erase with the use of light
A team of physicists headed by Prof. Sebastian Reineke of TU Dresden developed a new kind of storing information in fully transparent plastic foils. Their innovative idea is now published in the renowned online journal “Science Advances”.
These novel tags can be manufactured in any size. The low material costs of fewer than two dollars per square meter promise a wide range of application scenarios: Information like barcodes, serial numbers or addresses can be hidden for on-demand readout only. Also, these invisible tags could lift document security and anti-counterfeiting to a whole new level.
