EAST RUTHERFORD, N.J.—Hudson announced it is the first retailer in the travel industry to offer Amazon’s palm recognition service, Amazon One. Amazon One is now available at Hudson Nonstop, uses Amazon’s Just Walk Out technology, at Dallas Love Field Airport (DAL).

Hudson Nonstop at DAL allows travelers to enter the store and pay in two ways. They can either insert their credit or debit card, or they can hover their palm over the Amazon One device at the store’s entry gate. First-time Amazon One users can sign up at the dedicated Amazon One enrollment kiosk located outside of Hudson Nonstop to associate a credit or debit card with their palm signature before entering the store.

If a traveler has previously enrolled in Amazon One at an Amazon Go, Amazon Books, Amazon 4-star, Amazon Fresh, Amazon Pop Up location or Whole Foods Market store, they will not need to visit the enrollment kiosk. The Amazon One device will recognize their palm, allowing them to enter.

Once travelers have completed their shopping, the card linked to their Amazon One ID will be charged for the items they selected and left the store with.

“The introduction of Amazon One to the Hudson Nonstop store at the Dallas Love Field Airport brings another convenient way for travelers to quickly shop and be on their way,” said Dilip Kumar, vice president of physical retail and technology at Amazon.

“With consumers increasingly demanding greater convenience and speed, we look forward to leading the charge in introducing new innovative solutions and retail concepts that are designed to meet and exceed the expectations of our travelers and partners,” said Jordi Martin-Consuegra, chief executive officer of Hudson.

Hudson currently has two Hudson Nonstop stores powered by Amazon’s Just Walk Out technology—one at DAL and the other at Chicago Midway International Airport.

Amazon recently launched its Just Walk Out technology at select Whole Foods Stores. One store will open in Washington, D.C., in the Glover Park neighborhood, and the other will be in Sherman Oaks, Calif. Convenience stores are also utilizing checkout-free experiences to minimize friction for customers. Choice convenience stores in Denver offer self-checkout, walkout technology and an app, which all sync and communicate with each other.
