Zusammenfassung: | Systems, devices, and methods for authenticating a value article are provided herein. In an embodiment, a system for authenticating a value article that includes a luminescent material includes a portable computing device and an authentication device that is physically and electronically separate from the portable computing device. The portable computing device includes a microprocessor and a data receiver. The authentication device has the capacity to electronically connect with the portable computing device, and the authentication device includes an exciting light source, a photodetector, and a data transmitter. The exciting light source is provided to excite luminescent material of the value article, and the photodetector is provided to detect emitted radiation from the luminescent material after excitation. The data transmitter has the capacity to transfer a detected radiation signal or data derived therefrom from the authentication device to the data receiver of the portable computing device when electronically connected. |
