Style Guide
Final Design
High-fidelity prototypes will be designed and tested rigorously to ensure that the self-checkout system aligns precisely with user expectations and preferences.
When using the self-checkout machine, customers are prompted to scan items on the main screen. For assistance or extras like bags, a button is available at the bottom right. To ensure a fast checkout, options for bags or scanning membership cards won't automatically appear during the process.
Checkout Process
When a customer wants to purchase fresh products that do not have scannable codes, they have the option to input the product's name and then weigh it before adding it to their shopping cart.
Buy Fresh Products
To purchase age-restricted items, the system prompts for age verification via camera or directly with staff.
Camera verification analyses the customer's face; if unsuccessful, a valid ID must be shown to staff.
Customers can also opt to verify their age by presenting their ID to a staff member directly.
Buy Age Restrcited Product
When a customer intends to purchase a product with a security tag, the system will identify the presence of the security tag and guide the customer on how to remove it.

Reflection
The system aims to improve self-checkout, especially for age-restricted and security-tagged items, with visual instructions and assistance features. However, reflection is crucial to ensure it truly optimizes the shopping process.
How well does it handle these items and what improvements are needed?
Are the instructions effective and clear enough?
How often is the assistance feature used and what do users think about its effectiveness?
How does the system meet user expectations and what changes could make the checkout journey better align with their needs and emotions?
