She/he could even scan products using a scanner which enters the price of a particular product being scanned. The person using cash register at the counter can key in the products and look for PLUs (Price looks ups) against the products. Businesses that use barcodes on their products have barcode scanners that can be attached to the cash register. It indicates the amount of each sale and records the amount of cash received. Cash registers consist of keyboard that is used to input entries, a drawer to hold cash (notes and coins) and a printer. Business owners who do not wish to invest in POS Systems find cash registers easy to manage their small to medium businesses. Cash Registers CASH REGISTERS-HOW A SIMPLE MACHINE CAN HELP YOU WITH SALES Cash registers made their way in Point of Sale in 1800s and have since come a long way.Cash drawers can be printer or terminal driven. They may be the simplest part of your POS but making sure you have the right cash drawer is key. Cash Drawers Cash drawers are one of the core components to every Point of Sale System.The twelve digits are further divided as the first six numbers – identification number of the manufacturer, next five digits – the item’s number, last digit – check number, which is to verify if the barcode is scanned correctly. It consists of two parts – the vertical black and white stripes (barcode) and a 12 digit UPC number. Most of the products have a linear barcode and is easy to recognize visually. HOW DO BARCODE SCANNERS WORK? Barcode is of two types – Linear and 2D. The initial invention included the use of Morse Code, thus, giving rise to ‘Linear barcode system.’ Later, the linear system was replaced by circular rings and was known as ‘Bulls-eye system.’ Technological advances brought innovations in barcode scanners and, in 1973, barcode developed by George Laurer was widely accepted for its simplicity and power to hold more information. When the question ‘how to automatically read product information?’ arisen Silver, along with his friends, experimented with various potential solutions. Barcode Scanners THE ORIGIN OF BARCODE SYSTEM The idea for modern Barcode system originated back in 1948 in the mind of a graduate student Bernard Silver from Drexel Institute of Technology, Philadelphia.
