What is an electronic wallet? from AlanWeb's blog

An electronic wallet is an account in an electronic payment system, a kind of analogue of a bank account. 

You can access the site of such a system from your computer, or from your smartphone, by installing a mobile app. The system displays how much electronic money you have. This money can be withdrawn from the e-wallet to a bank card or in cash, or deposited from a bank card or in cash through terminals.

 is easy enough. You need to choose an electronic payment system, go to its website or download a mobile app and register there by entering your personal details.
