Secured miniaturized system-in-package contactless and passive authentication devices featuring NFC

The presented devices provide better HF-coupling characteristics than Coil-on-Chip approaches, which also enable verification of authenticity of tagged products through NFC-enabled smart phones. Thanks to the miniaturized package sizes of 3 × 3 mm, integration into high-priced products, casings, consumable materials, etc., can be achieved in a discreet way. Furthermore, the integrated CIPURSETM chip enables not only the anti-counterfeiting use-case, but also micropayment, ticketing, access control, and password storage in a secured way. Therefore, this miniaturized contactless authentication solution will open up whole new fields of applications.
