Abstract
Radio frequency certificates of authenticity (RFCOAs) and associated scanners and methods are presented. In one implementation, an array of miniaturized antenna elements in an RFCOA scanner occupies an area smaller than a credit card yet obtains a unique electromagnetic fingerprint from an RFCOA associated with an item, such as the credit card. The antenna elements are miniaturized by a combination of both folding and meandering the antenna patch components. The electromagnetic fingerprint of an exemplary RFCOA embeddable in a credit card or other item is computationally infeasible to fake, and the RFCOA cannot be physically copied or counterfeited based only on possession of the electromagnetic fingerprint.
