The term Digital Wallet, also known as E-Wallet, is a digital tool that enables users to make monetary transactions electronically through smartphones, smart devices, and computers. Apart from online and offline transactions, they are used to authenticate user credentials. A digital wallet can store complete user information including credentials, debit cards, transaction history, and personal details, so users need not have to carry the physical cards/cash with them. Some digital wallets allow users to store money, such as a cryptocurrency digital wallet like Coinbase. Through this, users can convert their money into cryptocurrency. Digital wallets have mainly two components, software, and information. The software component stores personal information and provides security and encryption of the data. The information component is a database of details provided by the user which includes their name, shipping address, payment method, amount to be paid, credit or debit card details, etc.
