Nowadays, point-of-sale systems have become an integral part in retail stores. The sole purpose of POS system is to make the process of sale and purchase easy and organised. Ideally, a point-of-sale hardware includes a POS computer, keyboard, cash drawer, POS monitor, customer pole display, barcode scanners and receipt printers. Barcode scanners are used in retail business for a myriad of different reasons. Warehouse owners and retailers use barcode scanners to keep a tally of several items and keep an eye on their prices and stocks. These scanners read barcodes printed on various surfaces of the products with the help of decoder circuitry which converts the barcode into a number. Barcode scanners are highly useful tools to store the information that is mention on the products in the form of barcodes. The scanners register the details in quick time and help the people on counter to calculate the prices. These scanners work by having a beam of light that converts the code on a product into electronic impulses and then a decoder converts these impulses in data that we can read easily. The data then can be supplied to a computer for analyzing it and to have it on thermal receipt printers. Types of barcode scanners include hand-held scanners, cordless laser barcode scanners, Omni directional desktop barcode scanners, area imager, USB scanners, wand scanners and PDA scanners. A barcode scanner is useful in POS system because- 1)It brings accurate results 2)Improves operational efficiency with quick recording of information 3)Saves time by enhancing the speed of data processing 4)Reduces error 5)Easy-to-install and use 6)Saves cost 7)Tracks the movement of items Like barcode scanners, thermal receipt scanners are also vital to the POS system. Thermal receipt printers are better than inkjet printers because they can be used by the sales personnel on the field and even without electricity. Thermal printers use heat-sensitive receipt paper to create an image through a chemical reaction. The initial cost of thermal receipt printers is higher than that of inkjet printers, but in long-term it comes out be a good investment decision. There are some models of thermal receipt printers that can print 2-color as well. Thermal receipt printers are beneficial for retail stores that need faster operation. They are not suitable for heat-intensive environments. Some of the benefits of a thermal receipt printer include- a)Faster print throughput- The technology used in a thermal receipt printer facilitates the printing speed. b)Leads to shorter checkout time and shorter lines of customers- An efficient thermal receipt printer helps in performing quick transactions at the sales counter resulting shorter checkout time and lesser time spent by customers in the waiting lines. c)Improved receipt durability- The quality of receipt produced through a thermal receipt printer is better than that of others, making them more durable. d)Almost silent performance- Unlike inkjet printers that are noisy, thermal receipt printers produce the receipts quietly. e)Cuts cost- With the help of a thermal receipt printer, retail owners can save cost generally spent on traditional receipt printing. f)Allows payment through credit cards- Receipt printers facilitate payment through credit cards, making it a sound investment.
