Dr. Ted Long explains the implementation of a QR code system for gathering food feedback from shelter residents. This system aims to improve the quality and variety of meals provided in the shelters.

• QR codes are placed on walls in shelter facilities, clearly labeled in different languages
• Residents can use their phones to scan the QR codes and provide specific feedback on the food
• Wi-Fi is enabled at all sites to facilitate the use of this system
• The feedback collected through this system has led to the removal of certain meals and the addition of more popular options based on resident voting
• This approach provides a direct and accessible way for residents to influence the food options available to them
