WISeKey International Holding Ltd. announced the commercialization of WIS.WATCH, a secure mechanical watch powered by contactless secure hardware enabled wallet, designed to offer security and ease of use to cryptocurrency users. The WIS.WATCH can securely store users' private key and allows them to make contactless transactions, including bitcoin and other cryptocurrency transactions. WIS.WATCH uses a combination of Near Field Communication ("NFC") technology with highly secured solutions provided by the WISeKey Semiconductors and is now accessible through the WISeWallet App. Every time a contactless Blockchain transaction is initiated, including a Bitcoin transaction, the private key must be first validated using the NFC technology and then the transaction is enabled. While software wallets continue to get hacked, the secure hardware wallets have gained popularity as they are providing the most secure solution for transaction and payments. Through the WISeCoin Wallet app, hardware wallets have now become contactless and users can establish multiple private keys into the secure store using the same WISeWallet App and access these private keys while making transactions. WIS.WATCH is NFC capable and contactless, is designed with Secure Element that can add hardware authentication factor amongst other multifactor authentication techniques, and protects users' credentials and private keys, which are encrypted/decrypted with sophisticated cryptographic techniques. The WIS.WATCH benefits from the technology of VaultIC Secure Element which integrates software and microchips on the watch, similar to the technology that empowers VISA, MasterCard, Discover and First Data Corporation bank cards. WISeWallet App is compatible with most of the existing blockchain technologies and works as part of payment system using WISeKey Blockchain-as-a-Service ("BaaS") technology offerings. Thanks to WISeID NFC technology, the WIS.WATCH can be used as a unique personal key identifier and trusted device to access smartphones, applications, personal data and secured cloud storage. With the connected WIS.WATCH, secure storage and secure access to users' personal data, documents, and passwords becomes easier than ever. WIS.WATCH is the one stop solution for identity and information security solutions. Payment capability complements secure access functions embedded in the WIS.WATCH and empowered by WISeKey's semiconductors technology which are unique in the market. Secure access functions allow watch owners to unlock WISeID Mobile Application, through a technology which is designed to protect personal digital assets encrypted on consumer smartphones or tablets by storing encrypted replicas of them in a secure cloud buried in a Swiss Alps military bunker.
