GENEVA / New York – November30, 2021: Ad-Hoc announcement pursuant to Art. 53 of SIX Listing Rules - WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, AI, Blockchain, and IoT company, today announced that it will hold a metaverse holograminar during its Investor Day scheduled for December 13, 2021, at the Nasdaq MarketSite in Times Square, NYC.

WISeKey will be organizing a hologram transmission integrating its MyWISeID digital signature and strong authentication capability into the end-to-end encryption channels in hologram technology powered by its transmission software. By adding the ability to verify digital identities, users will be able to communicate securely to submit their vote remotely, conduct financial transactions, access health consultations and much more.

The WISeKey NFT platform is secured by WISeKey’s various security technologies enabling the authentication of digital identity based NFTs, physical objects as well as digital assets, in a safe end-to-end process. The user is in full control of its WISeID NFT and other NFTs need to request access to its identity information so WISeID NFTs users can decide by themselves what level of information they wish to share, thus keeping full control. The WISeKey approach to the Metaverse has as objective to provide safe infrastructure identity services based on blockchain technologies for a wide range of users, including individuals, corporations and government institutions. As our digital lives become increasingly digitalized, Metaverse will leverage the advantages of the internet to establish a virtual world for its users. Businesses and communities will depend on users’ digital identities to manage assets.
