About

sAxess

Features
Read full description

The Serenity sAxess card, developed by S Technology, is a cutting-edge biometric authentication solution designed to integrate multiple functions like Wallet solutions , secured access and many others. This card represents the convergence of blockchain technology through self custodial integrated wallet , accessible with biometrics, Through its integration with S Technology (Serenity) Blockchain layer sAxess plays a key role in S Technology's DeDasp ( Decentralised Data survivability protocol ) and RWS ( Real world services ) Key Features & Technology Biometric Authentication: At the core of the sAxess is biometric authentication. This provides a higher level of security compared to traditional authentication methods, such as passwords or PINs, by associating the cardholder's identity directly with their unique biological characteristics (e.g., fingerprint, iris scan, facial recognition). Biometric data, stored securely on the card, ensures that only the authorized user can access or control the data tied to their identity, whether it’s sensitive personal information or valuable digital assets. Integrated wallet:   The sAxess card is designed to integrate with EVM built in networks for decentralized storage of digital assets . The user can receive, store and send crypto assets from this integrated wallet. The user can open new wallet or migrate an existing EVM wallet into the sAxess card for better and safer log in through biometrics ensuring a seamless and secure onchain interaction. The biometric authentication which is the first step in the mobile app, makes it more safe and secure than other such wallets in the market . Blockchain integration :  sAxess card is integrated with a Blockchain layer where users can store , view and recover their wallet seed phrases for disaster recovery. This can also enables a succession mechanism based on simple inheritance or recursive succession based on the user's requirements . sAxess is a core component of DeDasp and RWS for 2 main reasons : The extra security the Biometrics validation of sAxess provides, also sAxess enables mass and mainstream adoption for Serenity's RWS ( Real world services) where clients can access their solutions/systems directly through biometrics validation.
