D4A is an online platform for selling and buying used disability equipment. It aims to connect people with disabilities in the most developed European countries with those in less developed countries, enabling them to purchase second-hand equipment to increase their social inclusion, mobility, and product quality. The offer will be structured in several user-friendly ways–by type of disability, product group, and interest (e.g., sports, culture) and will provide helpful information about the products themselves. Due to the language barrier, the team's goal is a multilingual system that works effectively in key European markets and later globally.
