How Does the POS System Work?

Here is the step-by-step process of how the POS system works

• The cashier or the user initiates the POS transaction on the POS system or machine by selecting “new transaction” or a similar option.

STEP 2: Item Scanning

• Each product has a barcode that contains information about the item, such as its name, price, and other details.

• The cashier scans the barcode using a barcode scanner connected to the POS system.

STEP 3: Product Information Retrieval

• The POS system retrieves the POS data or information about the scanned product from its database.

• This information may include the product name, price, quantity in stock, and any other details configured in the system.

STEP 4: Price Calculation

• The POS system calculates the total purchase cost based on the scan and price.

• It may apply discounts, promotions, or taxes as configured in the system to calculate an accurate final amount.

STEP 5: Payment Processing

• After calculating the total amount due, the customer provides payment for their purchase.

• The POS system supports various payment methods, including cash, credit/debit cards, UPI (unified payments interface), mobile wallets, and other electronic payments.

• The cashier selects the appropriate payment method on the POS system and completes the transaction.

STEP 6: Receipt Generation

• After successful payment, the POS system generates a receipt for the customer.

• The receipt typically includes details such as purchased items with their prices, discounts applied, the total amount paid, and transaction details like date and time.
