Cash registers are mechanical devices or machines that were used during the early days to record business transactions. James Ritty and John Birch invented the cash register in 1884. This mechanical device looked much like a clock and was used to record cents and dollars exchanged in stores. Improved versions of this register soon appeared. Advanced equipments have a keyboard, scanner, drawer, and printer attached to it. Traditional cash registers were known as a 'till' in UK and Commonwealth countries.  In the antique market, we can see cash registers made of wood, brass, marble, and other metals. They are usually big in size.
