The card includes a Bluetooth antenna and an NFC reader, which allows wireless communication with other devices safely.
The Bluetooth connectivity establishes an encrypted two-way communication with the mobile phone or computer to receive the transactions to be signed, and return them once signed or rejected after review on the e-ink screen.
The NFC connectivity allows the recording of the Recovery Card, as well as receiving its data to recover the HASHWallet in case of loss of the original card.
The use of this NFC chip as a payment method is planned for future developments.
In addition, the card is charged through this NFC chip wirelessly with the mobile phone and in the future we will offer a wireless charger that works at the same time as a connection to a computer, to synchronize the card with the desktop application HASHWallet Manager.
Remember that HASHWallet is a non-programmable device and the keys that it stores cannot be accessed or modified from the outside.
