A security document is disclosed which includes an electrical circuit embedded in a document substrate, where the electrical circuit includes a power source with at least one electroactive polymer power generator, and an optical display including at least one electroluminescent display element and at least one nanohole array which forms a layer of the electroluminescent display element. A method of authenticating a security document is also disclosed, the method including illuminating an encoded nanohole array in the security document with a focused light beam or laser light source emitting at least one defined wavelength of incident light, detecting a transmitted portion of the incident light transmitted through the nanohole array with an optoelectronic sensor, analyzing at least one wavelength of the transmitted portion of light to produce a detected signal, and comparing the detected signal with an authentication signal to authenticate the security document.
