SYSTEMS AND METHODS FOR FLEXIBLE COMPONENTS, FLEXIBLE CARDS, MULTI-LAYER BOARDS, MULTIPLE SENSOR DETECTORS, NON-TIME SMEARING DETECTION MECHANISMS AND ELECTROMAGNETIC FIELD GENERATORS FOR POWERED CARDS AND DEVICES

摘要

Die may be thinned using a thinning and/or a polishing process. Such thinned die may be flexible and may change operational characteristics when flexed. Detection circuitry may also be provided on the PCB and may be used to detect changed operational characteristics. The thinned die may be stacked, interconnected, and encapsulated between sheets of laminate material to form a flexible card or device. A powered card may include a circuit board with multiple layers, and may include multiple reader communication devices. One of the layers may include an RFID antenna. A powered card may include a plurality of types of sensors used to detect a read-head of a card reader.
