Calculator, adding machine and register may seem to be synonymous terms, but they are each very different machines. A calculator is a device that is able to perform an array of mathematical functions, and it may or may not have the means to print these answers on paper. An adding machine, usually used by accountants, is a machine that uses ink ribbon and paper to print the results of simple mathematical operations. A person uses a register to keep track of and to total money.
Not all businesses need a 10 key adding machine. However, they are helpful for a number of reasons:
1. Adding machines are relatively inexpensive.
2. Adding machines provide paper copies of amounts and totals.
3. Adding machines are simple to use.
If you decide to buy adding machines for your business, remember to keep everything you need for them in stock. You do not want to run out of paper, ink ribbons or batteries just when you need them most.
