THE FUTURE.

CBS 2'S ALICE GAINER EXPLAINS

HOW IT WORKS.

AFTER A YEAR OF TESTING, THE

FIRST AMAZON GO STORE IN

DOWNTOWN SEATTLE OPENED THIS

MORNING.

I WALKED OUT WITH THESE TWO

THINGS IN A MATTER OF 30

SECONDS.

THE CASHIERLESS STORE LETS

YOU WALK IN, GRAB YOUR ITEMS,

AND GO.

IT WAS FUN TO WALK OUT

WITHOUT TALKING TO ANYBODY.

THE PRICES SEEMED FINE.

THEY HAD SALES LISTED ON THEIR

APP.

HOW DOES IT WORK?

ENTER AND SCAN YOUR AMAZON GO

APP ON YOUR MOBILE DEVICE.

CAMERAS AND SENSORS TRACK WHAT

YOU PICK AND PUT INTO YOUR BAG

AND ALSO WHAT YOU PUT BACK.

ONCE YOU LEAVE, YOUR ACCOUNT IS

CHARGED.

WE'VE HAD PEOPLE DOING SELF

CHECK OUT FOR A WHILE NOW.

BUT THIS IS JUST A MORE

ADVANCED VERSION OF IT.

AND IT MAKES IT A LOT MORE EASY

TO DO.

DAVID, EXECUTIVE EDITOR AT

CNET SAYS WHILE REACTION TO

THIS NEW WAY OF SHOPPING HAS

BEEN MOSTLY FAVORABLE.

THERE'S ALWAYS THE OTHER SIDE

TO THE TECHNOLOGY.

YOU KNOW ALL THE DATA

COLLECTED ABOUT YOU, DO YOU

REALLY WANT THAT -- THERE'S A

TRADE OFF.

AS FOR WHAT'S DONE WITH THE

DATA.

WE NEVER KNOW, WE ALWAYS

DISCUSS THIS WITH AMAZON W THE

AMAZON ECHO, IT'S LISTENING TO

YOU IN YOUR HOME.

IT KNOWS WHAT QUESTIONS YOU'RE

ASKING IT.

SO AMAZON IS ABOUT COLLECTING

DATA.

IN A CITY FILLED WITH PEOPLE

WITH ZERO PATIENCE.

HOW WOULD A STORE LIKE THAT

FAIR HERE.

NO LINES.

I'M ALL FOR IT.

IF YOU'RE NOT INNOVATING

YOU'RE KIND OF BEHIND.

I THINK THAT'S HAPPENING WITH

THE MALLS AND ALL THE RETAIL

STORES YOU'RE SEEING THAT.

I THINK IT'S GOOD THAT AMAZON

IS INNOVATING.

THEY'RE DOING THE RIGHT THING.

AND FINDING A WAY FOR SHOPPERS

TO WANT TO COME TO THE STORES.

LEST YOU THINK HUMAN

INTERACTION GOES THE WAY OF THE

CHECK OUTLINES, AMAZON SAYS

THERE WILL BE EMPLOYEES IN THE

STORE COOKING PEOPLES AND

HELPING CUSTOMERS.

-- COOKING MEALS AND HELPING

CUSTOMERS.
