e-Wallet

Electronic money, or e-money, is the money balance recorded electronically on a stored-value card. These cards have microprocessors embedded which can be loaded with a monetary value. Another form of electronic money is network money, software that allows the transfer of value on computer networks, particularly the internet. Electronic money is a floating claim on a private bank or other financial institution that is not linked to any particular account.[1] Examples of electronic money are bank deposits, electronic funds transfer, direct deposit, payment processors, and digital currencies.

Electronic money can either be centralized, where there is a central point of control over the money supply, or decentralized, where the control over the money supply can come from various sources. Electronic money that is decentralized is also known as digital currencies. The major difference between E-money and digital currencies is that E-money doesn't change the value of the fiat currency (USD, EUR) it represents, but digital currency is not equivalent to any fiat currency. In other words, all digital currency is Electronic money, but Electronic money is not necessarily digital currency. Many mobile sub-systems have been introduced in the past few years including Skrill, NETELLER, PayPal, AtwPay, Google Wallet and Apple Pay
