Shopping cart software is software used in e-commerce to assist people making purchases online, analogous to the American English term 'shopping cart'. In British English it is generally known as a shopping basket, almost exclusively shortened on websites to 'basket'.
The software allows online shopping customers to accumulate a list of items for purchase, described metaphorically as "placing items in the shopping cart". Upon checkout, the software typically calculates a total for the order, including shipping and handling (i.e. postage and packing) charges and the associated taxes, as applicable.
Licensed vs. Hosted Shopping Carts
Shopping cart software can be generally categorized into two main categories.
- Licensed software: The software is downloaded and then installed on a Web server. This is most often associated with a one-time fee, although there are many free products available as well. The main advantages of this option are that the merchant owns a license and therefore can host it on any Web server that meets the server requirements, and that the source code can often be accessed and edited to customize the application.
- Hosted service: The software is never downloaded, but rather is provided by a hosted service provider and is generally paid for on a monthly/annual basis; also known as the application service provider (ASP) software model. Some of these services also charge a percentage of sales in addition to the monthly fee. This model often has predefined templates that a user can choose from to customize their look and feel. Predefined templates limit how much users can modify or customize the software with the advantage of having the vendor continuously keep the software up to date for security patches as well as adding new features.
PCI Compliance
Main article: Payment Card Industry Data Security Standard
The PCI security standards are a blanket of regulations set in place to safeguard payment account data security. The council that develops and monitors these regulations is composed of the leading providers in the payment industry: American Express, Discover Financial Services, JCB International, MasterCard Worldwide and Visa Inc. Inc. International. Essentially, they define the best practices for storing, transmitting, and handling of sensitive information over the internet.[1]
Shopping Cart Software providers are responsible for any liability that may occur as a result of non-compliance to VISA regulations. For this reason business owners and online merchants must use only VISA Certified Shopping Cart Software providers as listed on Visa's Global List of PCI DSS Validated Service Providers.[2]
