Secure chip

Data stored on the Ace Card is protected while sitting on a certified secure chip(a hardware with temper-resistant security), that saves sensitive credentials for access to the blockchain in a secure spot that is not publicly accessible. All of this data is transmitted over a secured communication protocol and can only communicate with the respective Ace Wallet app.

Ace Card common storage

The Ace Card also provides a common storage. The storage is available for the user  and can be utilized in the same way as with any standard microSD Memory Card. However, no sensitive data is stored here. That data is stored happens in a special, secure part of the microSD card which can only be accessed by the Ace Wallet app via two step authentication.

Encrypted communicationsing

The mobile device communicates with the Ace Card  a specially developed protocol. The whole communication is encrypted and password protected by the Ace Card owner. This communication cannot be captured by a “man-in-the-middle attack” and only the Ace Wallet can communicate with the secure chip of the Ace card.
