Temperature Test
• Domino's Pizza Pickup Station is a student-designed, cost-
efficient, self-serve system that will allow prepaid customers to
avoid the line and pick up their order.
• Key technical challenges of our project include the following:
¾ Developing a secure solution through customer identification.
¾ Modification of existing hardware to implement our system.
¾ Integrating the software and hardware for fluid customer
and employee experiences.
Project Success:
A prototype of the pizza pickup station with four doors has been
designed and built. An Android application and a back-end service
to manage customer orders has been developed. The software
and hardware has been integrated and validated for fulfillment of
stakeholder objectives.
Next Steps :
1. Implement defenses to common software security
vulnerabilities.
2. Attach more powerful signifiers for customers and employees.
3. Use production-level NFC hardware for a more fluid customer
experience.
4. Provide an intuitive graphical user interface for
employee operation.
