Frequently Asked Questions | 
Just Walk Out

What if I do not have a mobile phone or the app?

Using the Triton2Go mobile app provides a seamless experience and allows you to use your Triton Cash or Dining Dollar accounts, in addition to a credit card. Visitors to campus have the option to use a credit card to enter the market. There is no cash option, as all UC San Diego Residential Dining locations are cashless.

How does Just Walk Out technology know when a product is taken and by whom?

Just Walk Out technology is made possible by artificial intelligence like computer vision and deep learning techniques, including generative AI, to accurately determine who took what in any retail environment. Amazon built synthetic datasets to mimic millions of realistic shopping scenarios—including variations in store format, lighting conditions, and even crowds of shoppers—to ensure accuracy in any environment. The technology detects what shoppers take from or return to the shelves and creates a virtual shopping session. When guests have completed their shopping experience, they are able to leave the store without having to wait in line, and their choice of payment method will be charged for the items they took with them.

Who do I contact if I am charged for items I did not take?

If you believe you were incorrectly charged for an item, you can submit a support request through the Triton2Go app or at support.ucsd.edu. Please include a copy of your receipt with the ticket to expedite resolution.

What is tailgating and how do I avoid being charged for someone else's purchases?
