Design a UI interface for a grocery store checkout system.
For a grocery store checkout system, the user interface should be simple, intuitive and easy to use. Here is an example of how the design could look:

1. **Header section:** This section should display the store's logo, name, and location, so customers can easily identify it.

2. **Scanner and Input section:** The main part of the interface is the scanning and input section. This would consist of a scanner that will scan the barcode of each item that is being purchased. Additionally, there could be a keypad or touch screen for manually entering items that do not have a barcode, such as fresh produce.

3. **Item display section:** As items are scanned or manually entered, they should be displayed on the screen in a list format. Each item should display the name, quantity, and price, as well as a small image of the product for easy identification.

4. **Total and Payment section:** This section should display the total cost of the purchase, including any taxes or discounts. It should also include options for payment, such as cash, credit card, or mobile payment. Clear buttons should be displayed for customers to choose their preferred payment method.

5. **Customer interaction section:** The interface should also have a section for customer interaction, such as a thank you message or survey. This could be displayed after the payment has been processed and could include an option to print or email the receipt.

Overall, the design of the UI interface for a grocery store checkout system should prioritize efficiency and ease of use, making the checkout process as smooth and quick as possible for customers.
