What is the difference between a cash transaction and a credit transaction?
A cash transaction uses currency (dollars and cents) to pay for products or services. A credit transaction means that you are posting the transaction to a credit card or loan. In this case, the merchant gets paid (often the next day) for products or services rendered, and you pay the loan issuer or credit card company back. Sometimes, there are fees involved (a percentage of the transaction amount) to use a credit card - especially if you don't pay the issuer back within the established terms, which is called interest and finance charges.
