A POS system dramatically speeds up the checkout process. You can rapidly discover goods, assign orders to consumers, and apply discounts if you have a consolidated database of your products, pricing, and customers. The process is significantly faster if you use a barcode scanner. Customers do not want to wait in line for an extended period to finish their transaction. According to Shamayun Miah, you can limit the number of consumers who leave your store without purchasing if you use an effective POS system.
