An ever-growing number of biometric authentication services. Next is "external liberation"

Try Amazon One

Details about Amazon One are summarized in a series of articles in a separate magazine, but there are three ways to enter stores that have this mechanism: You can choose.

Instead of using the conventional Amazon Go app at stores that have introduced Amazon One, you can enter and exit the store with a two-dimensional code that can be displayed on the Amazon app.

To be precise, you use the code reader device next to the Amazon One device, but if you load the corresponding screen of the Amazon app here, you can enter like a conventional Amazon Go. However, since the operation of the Amazon app changes depending on the region of the linked account, for example, if you register a Japanese account, the screen configuration will change, and you will not be able to display the 2D code required for entering and leaving Amazon Go. .

Therefore, when ordinary Japanese travelers use stores like Amazon Go in the future, they will choose the first “palm” authentication or the third “credit card” entry. When you enter the store, insert your credit card into the Amazon Go device to open the gate, and when you leave the store, your card will be charged.

The growing number of biometric authentication services.

For "palm" authentication, the credit card and "palm" information are linked using the Amazon One device installed at the gate or the registration machine installed at the entrance of the store.

After inserting the credit card, the registration process is completed by loading the "palm" information in the order of right and left, and finally entering the phone number. At this point, it has not been linked to your Amazon account, but you will receive an SMS short message to the phone number you entered last, and clicking on the link in it will take you to a site for linking with your Amazon account. Transition. As a result, it will be possible to check usage records on Amazon One on the site.

In addition, the Starbucks Pickup store that just opened in New York City the other day is equipped with the unmanned payment system "Just Walk Out" as standard, and it looks like a combination of Starbucks and Amazon Go. Although it is a business form, Amazon One is also available here. In this way, it can be said that Amazon One is gradually expanding its range of use beyond the group brand "Amazon".

However, as you can see from the video in the previous article, Amazon One's "palm" authentication is frustrating because it is not easily recognized.

When I entered and exited the Amazon Fresh store using Amazon One

After retrying the video many times, I shot it in a "fairly" used state, so it went relatively smoothly, but at first When I registered for Amazon One on , it took nearly 10 minutes just to register because the "palm" information was not read. At Whole Foods, you'll see guide-like protrusions installed in the Amazon One device to make it easier to keep your hand above the device about 10cm, which is required for recognition.

This "slowness" of recognition is a big problem, but the problem is the specification of "personal information management" of Amazon One. This is covered in detail in the article linked earlier, but in Amazon One, the other party recognizes information that should not have been registered, and notifies that fact on the screen.

The main theme of this time will be this part.
