When you sign up with a company to process your credit cards, they will tell you about several options for a credit card machine. The most well-known option is the small unit which will accept the swiping of a credit card, or it will accept the punching in of all of the numbers on the customer’s credit card. It can also be used to refund money to the customer. At the end of the day it “settles” the account, giving you the total for the sales and the number of transactions that went through.
Some credit card processors provide this terminal for you free of charge – others may charge up to $200 for it, and still others may lease them to you for a monthly fee. Make sure you ask!
