PQC CARD Dual leverages proprietary memory-saving technology to successfully optimize memory capacity for handling PQC’s extensive cryptographic processing. Against this backdrop, TOPPAN has developed PQC CARD Dual, the world’s first PQC equipped dual-interface smart card, by leveraging memory-saving technology developed for smart cards, along with knowledge gained through quantum and post-quantum cryptography R&D. PQC CARD Dual Features・World’s first both contact and contactless smart card featuring PQCPQC has been successfully applied to dual-interface smart cards that can perform both contact and contactless transactions. At the same time, the standard OS used for smart card platforms is known to take up a large amount of memory space. Looking ForwardTOPPAN aims to carry out PoC testing for PQC CARD Dual and related systems within fiscal 2026 for industries requiring a high level of security, such as public services and medicine.
