• 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:

Ø Developing a secure solution through customer identification.

Ø Modification of existing hardware to implement our system.

Ø 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.
