WISeKey's CEO, Carlos Moreira will appear on Benzinga's 'Power Hour' to 
discuss WISeKey's NFT technology, today at 1:30 p.m. ET 
 
   Geneva, Switzerland -- March 26, 2021 -- WISeKey International Holding 
Ltd (SIX: WIHN, NASDAQ: WKEY), a Swiss based cyber security, IoT, AI 
platform company, today announced that it will auction the first ever 
secure luxury NFT watch on March 31, 2021, using Open.Sea NFT 
MarketPlace. The highest bidder will receive the high-end NFT watch with 
an embedded digital certificate using a secure element with a 
cryptographic public--private key pair unique to each watch. 
 
   WISeKey is launching this auction to demonstrate its technology and 
encourage luxury watch brands to start using it to auction their 
high-end watches through WIS.Watch NFTs. The company successfully 
launched this week its WISe.Art, a digital certificate of authenticity, 
a NFT for art pieces that will live forever on the blockchain, unchanged 
and unchallengeable, as proof of the buyer's ownership. This 
announcement generated strong interest from the luxury and art community 
and WISe.ART is now operation using OpenSea NFT MarketPlace -

   This method secures watches using cutting-edge authentication 
microprocessors combined with identity blockchain technology, which 
together with on-the-ground measures ensures the authenticity of the 
artwork. See video

   A WISeKey NFT is a unit of data on the blockchain, where each NFT 
represents a unique digital item, such as an artwork, audio, video, an 
item in video games or other forms of creative work. While digital files 
themselves are infinitely reproducible, NFTs representing them are 
traced on their underlying blockchains and provide buyers with proof of 
ownership.  Blockchains such as Ethereum, Bitcoin Cash and Flow, each 
have their own token standards to define their use of NFTs. 
 
   WISeKey, the first company in the world to use dual factor 
authentication combined with blockchain technology to secure luxury 
watches, currently protects over 2.5 million luxury watches. Since 2010, 
WISeKey has collaborated with manufactures of luxury watches deploying 
this unique technology to integrate semiconductors tags powered with its 
VaultIC154 NFC secure element and provide brands with the ability of: 
 
 
   -- issuing a storage device comprising of a digital certificate of 
      authenticity 
 
   -- checking, when required, the validity of the digital certificate of 
      authenticity 
 
   -- modifying, when required, the status of validity of the digital 
      certificate of authenticity. 
 
   -- Dematerialization and creation of a Digital Twin with its corresponded 
      Non-Fungible Token 
 
 
   These tags, when placed on any product and tapped by an NFC phone, 
securely authenticate, and track the product much like an embedded 
ePassport and confirm the identity of the product on the blockchain 
ledger. This technology has received a patent in the USA

   Furthermore, WISeKey's technology creates Watch Birth Certificates, 
digital identities which are analogous to birth certificates and can be 
converted into NFTs.  The Watch Birth Certificate is signed, or 
"certified" by a trusted authority and contains basic information such 
as date & time of manufacture (birth), company (parents), and type of 
product.  This digital identity, used throughout the watch lifetime, 
allows the watch to become a "Trusted Object" of the Internet, prove its 
identity and provide verifiable data. 
 
   The Watch Birth Certificate is based on a cryptographic public--private 
key pair that is unique to each IoT device.  The public key for this key 
pair is part of the certificate and can be freely distributed, while the 
private key is used whenever the IoT device needs to verify its identity 
or to sign data to ensure cryptographic integrity. It is the private key 
that represents the essence of the identity of the IoT device. 
 
   A WISeKey NFT virtual meeting involving stakeholders on the Art and 
Luxury Ecosystem will be held on April 14, 2021 at 9:00 am ET
