In addition, the POS system may speed up transactions - which is critical in a restaurant or coffee shop, for example, where a long line at the counter leads to grumbling customers.

In theory, a company knows how many lattes, sweaters, or golf clubs left the storefront, and if any were returned. With the POS technology, the system's software uses the barcode on the label of the item you bought (or the key code for the particular entrée or drink, in the case of a restaurant) as an inventory regulation system as well as an efficient way to control the transaction.

Think about how often you use a debit or credit card for transactions - buying gas, paying for your daily latte or groceries, or purchasing that awesome new skirt or a set of golf clubs.
