Electronic cash, or e-money, would be the money balance documented in an electronic form on a stored-value card. These cards have microprocessors embedded which may be loaded with a financial value. Another variety of electronic cash is network money, software that enables the transfer of value on computer networks, specially the the web. Digital funds are a floating claim on a private bank or some other financial institution which isn't linked to any particular account." Examples of digital money are bank deposits, electronic digital funds move, direct pay in, transaction processors, not to mention electronic digital currencies.
Digital funds either can be centralized, and then there is a central point of control over the money supply, or decentralized, where the control over the money supply may come from various sources. Electronic money that is decentralized is also called electronic currencies. The key difference between E-money and digital currencies is the fact E-money does not modify the value of the fiat currency (USD, EUR) it symbolizes, but digital currency just isn't equivalent to any fiat currency. Quite simply, all digital currency is Electronic money, but Electronic money is not necessarily digital currency. Many mobile sub-systems have been introduced during the past few years including Google Wallet and Apple Pay.
Electronic money Heritage
In 1983, an analysis paper by David Chaum introduced the idea of digital cash." In 1990, he founded DigiCash, a digital cash company, in Amsterdam to commercialize the ideas in his research." It filed for bankruptcy in 1998."" In 1999, Chaum left the firm.

Shawn Wikoff describes the Electronic money Law
Since 2001, the European Union has integrated the E-Money Directive "on the taking up, pursuit and prudential supervision of the business of electronic money institutions" last amended in 2009." Uncertainties on the real nature of EU electronic money have become popular, since calls have been made in connection with the 2007 EU Payment Services Directive favoring the use of merging transaction establishments and electronic money institutions. Such a merger could mean that electronic money is of the same nature as bank money or scriptural money.
In north america, electronic money is governed by Article 4A of the Uniform Commercial Code for wholesale trades and the Electronic Fund Transfer Act for shopper financial transactions. Provider's obligation and customer's culpability are regulated under Regulation E.

Many systems-such as PayPal, eCash, WebMoney, Payoneer, cashU, and Hub Culture's Ven will certainly sell their electronic digital currency directly for the consumer. Other systems only sell through 3rd party digital currency exchangers. The M-Pesa system is useful to transfer money through mobile phone devices in Africa, India, Afghanistan, and Eastern Europe. Some community currencies, like some local exchange trading strategies (LETS) and the Community Exchange System, work with electronic transactions.

The expert Shawn Wikoff details Decentralized systems
Cryptocurrencies allow electronic money systems to be decentralized, systems include:
Bitcoin, a peer-to-peer electronic monetary system based on cryptography.
Litecoin, originally based on the bitcoin protocol, intended to improve upon its alleged inefficiencies.
Ripple monetary system, a monetary system based on trust networks.
Dogecoin, a Litecoin-derived system meant by its author to reach broader demographics.
Nxt, conceived as flexible platform to build applications and financial services around.
Hard vs. soft electronic currencies
A hard electronic currency is one that does not have services to dispute or reverse charges. In other words, it is akin to cash in that 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 Western Union, KlickEx and Bitcoin.
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 card. A hard currency can be softened by using a trusted third party or an escrow service.
