A transparent security system demonstrates multiple touchpoint operation of a transparent capacitive type sensor based on inkjet printed material. The active touch part of the device utilizes high transmittance values which makes it hard for the human eye to distinguish where the sensing part is located and increases the security level offered by the device. The system can be realized on both rigid glass substrate (used in windows, showcases, displays), as well as on flexible substrates (used in door lockers, and other curved surfaces). The demonstrator utilizes non-organic, and printed technology in both rigid and flexible forms.
