Cash registers are sold by office supply and electronics stores such as Staples, Best Buy and Office Depot. They can also be purchased from online retailers such as Amazon.com, or club stores such as Costco, BJ's, and Sam's Club.
Standard cash registers usually have a simple keypad and display that shows the individual prices of items purchased as well as the total price at the end of a transaction. More complex cash registers, such as digital point of sale cash registers, connect to a computer terminal to provide a more complete inventory management solution. These cash registers are used by businesses that have a large inventory.
