It is important for a cashier or for a sales agent to have an effective barcode scanner otherwise it will not be easy for them to track the prices they wanted to encode on their cash register. In today’s generation everything is fast phasing, if you are not updated with the latest technology, you will get behind. Just like if you don’t have the best scanner the customers will soon transfer to a store that is not using the manual type of tracking the prices of a certain product. Like of what happen at the store last week, the barcode scanner of the cashier was not functioning so she is typing the barcode one by one on her cash register. On her lane, she had the longest line of customers, later the customers left their purchases in a basket and leave. See how it affects the business? I guess they lost some income that day.
