Technology can be very confusing for a buyer, especially when there a hundreds of products to choose from and it is necessary to decide which will suit his or her needs. Knowing some basics about point of sale (POS) requirements will simplify things to a large extent. Here is some basic information about POS equipment for a beginner! Every POS system has some hardware requirements and needs physical input and output devices to carry out the commands of remote system software and to guarantee the smooth functioning of business transactions in a restaurant or a retail outlet. Some of the mandatory hardware includes computer terminals, receipt printers, cash drawers, magnetic stripe readers, check readers, monitors or screens, keyboards, barcode scanners, and customer display screens. These are aimed at time-effective and error-free sales transactions, where every activity is machine driven and manual input is minimal. Computer terminals with operating systems like Windows or Linux are essential to map the software into Windows or Java and to integrate it with the mechanical devices. Receipt printers for retail outlets and hotels come with cash drawer ports and both the printers and the cash drawers share a single port with the PC, leaving other PC ports free for other peripherals of the POS system. Barcode scanners read product information from the price tag of the products and feed the information into the computer, which then processes it and prints it. Magnetic stripe card readers and check readers are essential for vendors who accept payment through cards and checks. Apart from drawing money from the customer's account, these devices also prevent fake checks and credit card accounts from getting submitted. The scanners and readers are usually wedges in point-of-sale keyboards, which come with a maximum of 101 keys for industry-specific functions. Monitors and touch-screen displays are used as both input and output devices depending on the individual needs of a vendor. Fourteen-inch monitors are most widely used, but nine- or ten-inch monitors are used in some cases, especially when they are used as display boards for product or menu information and pricings. |
