Electronic Money
Electronic money (also known as e-currency, e-money, electronic cash, electronic currency, digital money, digital cash, digital currency, cyber currency) refers to money which is only exchanged electronically. Electronic Funds Transfer (EFT), direct deposit, digital gold currency and virtual currency are all examples of electronic money.
A number of electronic money systems use contactless payment transfer in order to facilitate easy payment and give the payee more confidence in not letting go of their electronic wallet during the transaction.
A hard electronic currency is one that does not have services to dispute or reverse charges. In other words, it only supports non-reversible transactions. Reversing transactions, even in case of a legitimate error, unauthorized use, or failure of a vendor to supply goods is difficult, if not impossible. The advantage of this arrangement is that the operating costs of the electronic currency system are greatly reduced by not having to resolve payment disputes. Additionally, it allows the electronic currency transactions to clear instantly, making the funds available immediately to the recipient. This means that using hard electronic currency is more akin to a cash transaction. Examples are TokenPay, Bitcoin, and Western Union.
A soft electronic currency is one that allows for reversal of payments, for example in case of fraud or disputes. Reversible payment methods generally have a “clearing time” of 72 hours or more. Examples are Paypal and credit cards.
A hard currency can be softened by using a trusted third party or escrow service.
