Screen

The Next Bank USB Key features a display screen, so you can verify all sensitive operations at a glance.

Buttons

Any operation on your USB Key is controlled by only 4 buttons. Secure crypto
asset transactions have never been so easy!

State-of-the-art Security

Your private key giving access to your coins is never exposed. It is protected
within a secure chip locked by a PIN code, the same type of chip used for
passports and credit cards.

Multicurrency

The Next Bank Smart Encryption Card S supports over 40 cryptocurrencies,
including Bitcoin, Ethereum and XRP, allowing you to manage multiple assets with
the same card.

Simplicity

A variety of data transfer methods link Next Bank Universal Wallet app.You only
need to attach the smart encryption card to the NFC-enabled mobile phone or
keep it very close to the phone (usually less than 4 cm), and then manage the
assets by simply operating on theNext Bank universal wallet app.

Secure Chip

The Smart Encryption Card is built-in a robust secure chip, engineered to
withstand sophisticated attacks: your private keys are safely isolated inside the
card.

Tamper Proof

No need for an anti-tampering sticker to protect your device! The secure chip
checks the integrity of your device each time it’s powered on – much better than
any sticker would.

Firmware verification

The bootloader verifies the firmware signature. The device only runs if the
firmware is correctly signed by SatoshiLabs. Otherwise, the USB Key warns you.

Special signature

Each smart plus password has a special signature based on an advanced dynamic security
algorithm, and can only authenticate one device after it is activated.
Signatures cannot be deciphereand your assets will be safely left. 

Reliable backup & recovery

Your recovery seed protects you against theft, loss or destruction of your device.
Simply restore the recovery seed, and your wallet is back.
