The Dangers of Shopping Online 
It's just so easy to spend excessively online because online shopping is done by credit card or debit card. Cash never leaves your hands so you don't think about how much you're spending. Beware of e-mail phishers, website pharmers, website / computer crackers, spammers, and scammers, too.
It's also so easy to never leave home (read: laziness).
Payment Processing 
Merchants open an e-commerce merchant account, also called Internet merchant account, in order to accept credit cards as a form of payment. Paypal, which is an online payment service, is also used to make transactions between a business and consumer. Digital wallets, also called e-wallets, give consumers a way of storing they payment information securely for e-commerce purchases.
Certain online stores also offer additional payment services that can be selected during checkout, such as Bill Me Later (a PayPal service) and eBillme. This option allows the shopper to defer their payment until after the checkout process is completed. This allows for greater convenience and security for the consumer since they don’t need their credit cards handy to pay and also do not need to give their credit card numbers to the online retailer. However, a credit check is required first and you must live in the United States and be of legal age. Many of these services also charge an interest rate which you should consider before selecting them. (Morley, Deborah, and Charles S. Parker. Understanding Computers: Today and Tomorrow. 13th ed. Boston: Course Technology/Cengage Learning, 2011. Print.)
Some online stores offer the option to save data like payment information, shipping details and preferences in a digital wallet, also known as an e-wallet. Some e-wallets are offered directly through the store's website, meaning when the customer goes to check out their data is already stored from their last purchase. This makes the purchase easier and quicker for the customer. There are also programs available to download this as a standalone service through your mobile phone. When purchasing from an online store, the app autocompletes the required data so the user doesn’t have to. E-wallets are typically encrypted to keep data safe and password protected to avoid fraudulent use.

Another option for people to be able to shop online without having to worry about hackers getting their credit card numbers is having a virtual account number. These numbers are basically disposable credit card numbers that can be used by the customers to buy things online and the charge will actually go onto their real credit card. Some virtual credit card numbers can be used multiple times but most are good for just one transaction. Since the number only has a one time use, if a hacker were to intercept it, they would not be able to use it to make other purchases.
