Is your Bluetooth connection secure?
Though, we use Bluetooth as a communication channel, and it will only be initialized when the wallet is turned on within a proximity of 10 meters. The design of our product uses an AES256 encryption to communicate between a wallet and a phone along with a dedicated pairing passcode. Thus, any unauthorized devices are prohibited to communicate with the card for data retrieval. Furthermore, the Secure Element chip inside of the card is critical, it is CC EAL 5+ certified which is equivalent to FIPS complied security level similar as US military’s requirement. Your most sensitive information like private key will be secured inside of this chip. This chip does the calculation of all the necessary algorithms and deliver only the result of the calculation (non-sensitive data) out to the phone via Bluetooth. It's quite impossible to break into the chip and get the private key out of this chip.
