"Digital commerce is the electronic buying and selling of goods."
When buying or selling goods online it is important to know if you are using a secure system that will keep you and your money safe. When putting information in on a site be very careful and make sure that it is a secure site before inputting personal and card information.
Ex: If you are shopping online, make sure that it is a trusted website and you have done some research over it to ensure it is not a scam before entering your payment information.
