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 HDH locations are cashless.

How does the technology work?

This streamlined shopping experience is made possible by using 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.

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 feel you have an incorrect charge you will be able to inquire using the support function through the Triton2Go app.

What other schools feature Just Walk Out technology?

Seven higher education institutions across the country feature this technology, Cal State Long Beach is the closest university to UC San Diego.

Will this lead to campus market cashiers losing their jobs?

UC San Diego does not anticipate any reduction in force as a result of this program.

Is CalFresh available at these locations?

CalFresh will continue to be available in its current format at markets that include the technology.

How much do I need in Dining Dollars or Triton Cash to enter the markets?

When generating a QR code in the Triton2Go app, the system will run a balance check to ensure that there is at least $20 in your account to enter the store.

What if I spend more than my account balance while in the store?

An HDH team member will reach out to assist you with resolving the remaining balance needed for your recent purchases.

Why was my credit card charged when I entered the store?

When entering the store using a credit card, a $20 pre-authorization will be sent to your bank or card provider. It is a temporary hold placed on a payment card to verify that it is a valid card and there are available funds. The preauthorization will not be debited to your account. It will disappear within a few days, depending on your financial institution.

How much will my credit card be preauthorized for?

When using the credit card payment feature via the Triton2Go app, there will be a $20 preauthorization. When utilizing a physical credit card or mobile wallet at the in-store credit card terminal, there will be a $50 preauthorization.
