The cash register is an indispensable office equipment in modern business activities. It can quickly and accurately complete transaction settlement and provide convenient cashier services for merchants. So how does the cash register work? Let's understand the working principle of the cash register. 1. Input Devices First, customers select the products on the cash register and scan the barcode or enter the product code. These information are input into the cash register through input devices (such as scanners or keyboards). 2. Data Processing When the product information is input, the cash register will process the data through internal programs. These data include product prices, quantities, discounts, etc. The cash register will quickly calculate the total price according to preset rules and algorithms. 3. Payment Processing Customers can choose different payment methods for payment, such as cash, bank cards, mobile payments, etc. The cash register will process accordingly based on the payment method. If it's cash payment, the cash register will calculate the change; if it's bank card or mobile payment, the cash register will connect to the bank or payment agency system for transaction verification and fund transfer. 4. Printing Receipts After completing the transaction, the cash register will print a receipt. The receipt will show transaction details, such as product information, prices, transaction time, etc. The receipt is an important proof of transaction, which helps merchants for financial management and customer service.
