My wife's family is engage in a merchandising business. There are numerous little items being sold on the store. Sometimes computation gets tough and to do it right and exact we bought this electronic calculating and note checking machine.
This machine has the numbers, operations and memory buttons for calculation. The buttons' sizes are good although the display monitor is relatively small but numbers are readable. Calculating is not hard because the machine is very sturdy. No need to hold it. Just put it on a flat surface and computes.
One thing best about this machine is the note checker. It is hard to be paid with fake money without knowing it. This machine helps in detecting fake money. It has magnet indicator and ultraviolet sensitivity adjuster that identify fake ones from the true ones.
My mother-in-law is very happy to have this. Although she knows some tips on how to check a fake bill, there is no problem if she will get a second opinion from this machine.
