Digital Cash

Digital cash aims to mimic the functionality of paper cash, by providing such properties of anonymity and transferability of payment. Digital cash is intended to be implemented data which can be copied, stored, or given as payment (for example, attached to an email message, or via a USB stick, Bluetooth, etc.).  Just like paper currency and coins, digital cash is intended to represent value because it is backed by a trusted third party (namely, the government and the banking industry).
