Encrypted NFC communication for X1 cards
The X1 Cards interface with the X1 Vault using NFC technology. NFC not only brings convenience to the overall user experience of the Cypherock X1, but also the potential to be interoperable with interfaces such as mobile phones and POS systems. A common criticism for NFC is that it may be possible for an attacker to read and modify the information that is stored on the X1 Card.
To address the concerns of NFC communication, Cypherock has implemented end-to-end encryption in the communication between the X1 Cards and the X1 vault. This implementation makes extracting any meaningful information from the Cypherock X1 impossible.
