Hybrid banknote with electronic indicia using near-field-communications
A hybrid high-security document includes a document and one or more independent light-emitting modules disposed on or embedded in the document. Each module comprises an antenna with multiple turns, an electronic circuit, and a light emitter mounted and electrically connected on a substrate separate from the document. The electronic circuit is responsive to electrical power provided from the antenna to control the light emitter to emit light. The electronic circuit can include a memory storing information relevant to the hybrid high-security document or its use. The information can be accessed by external readers providing electromagnetic energy to the hybrid high-security document. The hybrid high-security document can be a hybrid banknote.
