Description

WhisperCash is the first fully offline Central Bank Digital Currency (CBDC) that has the same properties as physical cash. It is capable of performing secure consecutive offline payments without compromising on security, privacy or accessibility. WhisperCash allows direct person to person offline payments without any server infrastructure or internet connectivity. The product comes in several form factors. The WhisperCash Lite is a keyring tag for contactless payments. The WhisperCash Basic is a SIM Card sticker that attaches to the SIM card of any mobile phone. The WhisperCash Pro is a battery-powered, self-contained CBDC wallet in a card form factor with an on-card eInk screen and keyboard. To ensure the payment infrastructure never gets interrupted, WhisperCash Satellite Stations are small terminals that can be hosted by Authorized Financial Institutions or Merchants for long-range transactions when other networks are down. They can also be used as standalone merchant terminals or synchronization devices in remote areas.
