Keepser: Maximum Security
The Keepser card is the most secure card in its class. Combined with an app installed on a smartphone, an unprecedented level of security is achieved by combining a highly reliable and secure authentication and storage device based on a patented segmented key technology. This means that, unlike all other solutions, private keys are segmented into several parts that are distributed among the different components of the Keepser Cold Wallet solution, providing an unprecedented level of security.
NFC Crypto Hardware Wallet: Your Safety on Autopilot
The app includes a complex library of functions that are activated via NFC. An administration console is provided to configure various settings. Depending on the model, up to 3 trust criteria can be defined to strictly control the conditions of authorised access, make the KEEPS invisible, manage a fleet of cold wallets or configure many other parameters. The accumulation of trust criteria is an innovation of the Keepser Cold Wallet solution. They may include criteria of geographic location (geofencing), network address (SSID), use of scanning, barcode or QR code scanning, and many other combinations. A state-of-the-art encryption generator ensures that the secrets can only be read by the intended recipient. Therefore, financial transactions or sensitive applications can be performed through reliable, private and anonymous communication channels.
Keepser's Technology
Keepser is the only internationally patented cold wallet in the world, awarded the Innovation Award at CES 2022.
The technology implemented in Keepser cards is also a world champion in the WORLD CHAMPIONSHIP OF INTERNATIONAL INVENTIONS IN GENEVA 2021.
Thanks to the association with an application installed on your smartphone, you achieve an optimal level of security by combining a highly reliable and secure authentication and storage device, based on segmented key technology. Unlike other solutions on the market, private keys are segmented into multiple parts that are distributed among the various elements of the Keepser Cold Wallet solution, providing an unparalleled level of security.
1. INTRINSIC SECURITY
KEEPSER cards are passive components (there is no hackable firmware) and are protected against physical attacks. All accesses used during manufacture and testing are automatically and permanently destroyed after the final validation.
2. NATIVE SYSTEM SECURITY
Each card has an encrypted unique identifier that is used to create native security and control functions, automatically managed by the Keepser Cold Wallet solution, which no one can access (neither the user nor Keepser).
3. ADMINISTRATION SECURITY
The administration interface, which is separate from the user interface and has a different access security, enables the user to define comprehensive security rules and associate trust criteria to each keeps. The administration and user interfaces can be managed separately by two different entities.
4. TRUST CRITERIA
1 to 3 "trust criteria*" can be defined for each keeps to control how the KEEPSER app can access and decrypt keeps or other data stored on the card. Trust criteria may include the following techniques: passwords, biometrics and, above all, geofencing, with the aim of prohibiting card use outside a geolocated area. (*The trust criteria depend on the Keepser model purchased).
5. DATA SECURITY
All keeps and trust criteria, as well as all keys and stored information are encrypted on the card with state-of-the-art technology using AES 256 or other techniques, as well as proprietary segmented key technology. Lost or stolen cards are not accessible and their data cannot be hacked.
6. CONNECTIVITY AND TRANSACTION SECURITY
The KEEPSER app can use the keys stored on the card to establish end-to-end encrypted communication channels and perform ultra-secure transmissions or transactions through any type of link (Ethernet, Wi-Fi, Bluetooth, NFC). Encryption keys and ECC mechanisms are updated in each session.
Contactless / NFC Tapping: In one step
Protect your data quickly and easily. Connect and transfer your data effortlessly, with a simple movement.
Just place your Keepser Cold Wallet behind a smartphone with an NFC antenna and the connection will be instantaneous. The card works with the Keepser mobile app and possibly a previously installed web browser plugin. Autofill or automatically log in to connect to secure websites or perform web transactions by simply placing the KEEPSER CARD near an NFC terminal with the KEEPSER app.
