It is used as an abbreviation for Electronic Commerce. It means that those who want to buy products or services and those who want to sell products and services come together electronically and shop online. In our country, electronic services began to be provided first and mainly by banks, and subsequently, commercial activities, especially retail sales, began to develop through online stores. Nowadays, most of the public services, both provided by the state and municipalities, are provided online. The spread of Online Commerce has also led to the development and spread of online payment systems.
