A cash register is a device that combines a secure drawer for storing money with the functionality to calculate and record sales transactions. When items are purchased, it tallies the total cost, processes the payment, and provides a printed receipt for the transaction.

Additionally, modern cash registers often come equipped with features to track sales data, supporting the broader point-of-sale operations critical for efficient business management.

4 types of cash register

Different businesses require different types of cash registers; here’s a look at the options that could suit your specific needs.

Electronic cash registers are the traditional backbone of retail checkout points. Equipped with a cash drawer and an input method, such as a keypad or touchscreen, ECRs are designed for durability and ease of use.

How to use a cash register?

A cash register is an essential tool for streamlining sales transactions and maintaining accurate financial records. Here’s a practical guide to using a cash register, which will ensure a smooth checkout process for both your staff and customers.

1. Prepare the cash register: Start by verifying that the receipt tape is loaded correctly, as this is vital for providing customers with transaction records.

2. Set up the cash drawer: Ensure that the cash drawer is organized, with designated spaces for different denominations of bills and coins. Keep larger bills and credit card slips underneath the drawer or in a secure compartment.

3. Scan items: Each product selected by the customer must be scanned by the cash register. This action records the sale and deducts the item from your inventory count while determining the price.

4. Calculate total: Once all items have been scanned, press the “Total” button. The cash register will display the total amount due, which you should communicate to the customer.

5. Process payment: Enter the amount tendered by the customer into the register. If they’re paying in cash, the register will calculate the change due. For credit card payments, process the card through the connected terminal, which will also print a receipt.
