The Seattle Seahawks took a loss against the Las Vegas Raiders on Sunday, but fans at Lumen Field who are into cashierless concession stands can at least count the day as a win.

The Seahawks debuted three more stores at the stadium utilizing Amazon’s “Just Walk Out” technology, designed to eliminate checkout lines and get fans back to their seats faster.

The new locations are on the main stadium concourse in sections 103, 105 and 123. They are called District Market, just like the store that opened in section 323 at the start of the season. The stores serve beer, wine, seltzer and non-alcoholic beverages as well as chips, peanuts, popcorn and candy. The original location is the only one which serves hot food right now.

Fans can enter, shop, leave and pay without having to deal with any food handlers or cashiers. The retail tech, used in Amazon’s Go convenience stores and some of its full-size Fresh grocery stores, relies on overhead cameras and sensors to track what customers grab. Payment is facilitated automatically via a credit card scanned at entry or a card that’s linked to a biometric scan of a shopper’s palm, via Amazon One.

Professional sports franchises across the nation are rolling out checkout-free stores from Amazon and other competitors in a test of the nascent technology.

Amazon licenses its tech for use in such places as stadium and airport stores. In addition to Lumen Field, Seattle’s two other sports venues use Just Walk Out. It’s in use at three stores in Climate Pledge Arena, where the Seattle Kraken play, and at T-Mobile Park, home of the Mariners, where it was introduced in May at a new “Walk-Off Market.”

In September, GeekWire interviewed fans at Lumen Field as they tried the technology for the first time before the Seahawks took on the Denver Broncos. Watch the video below:
