Retail giants have increasingly leveraged in-store technology that allows customers to buy products without waiting in line for the cashier. By marrying advancements in artificial intelligence and computer vision, cameras and sensors, and deep learning algorithms, these locations permit visitors to shop by simply picking up goods or placing products in their carts, nixing the need for a cash register altogether. The trend appears to be catching on across the retail industry . Kroger and Albertsons have partnered with smart cart startup Veeve for a pilot that has rolled out in select stores. Amazon Go stores began opening to the public in 2018.

It might feel as though artificial intelligence has reached a critical mass, but it hasn't. In fact, it's only starting to make an impact in some sectors, including retail. But, according to findings collected by KPMG, retail AI has room to grow -- and a lot of it. And by 2027, AI in retail will balloon to $19.9 billion from around $7.3 billion in predicted spending in 2022, per Meticulous Research. All this, and only half of the retail professionals believe they've scratched the surface of what's possible when the technology meets in-person shopping.

After launching it in Go stores and then bringing it to larger Fresh supermarkets, Amazon's cashierless "Just Walk Out" tech will soon arrive in two Whole Foods locations. The service, which lets you pick up goods from shelves and (yep) just walk out, is coming to new stores in Washington DC and Sherman Oaks, California next year, the company announced. "By collaborating with Amazon to introduce Just Walk Out shopping at these two Whole Foods Market stores, our customers will be able to... save time by skipping the checkout line," said Whole Foods co-founder John Mackey. As we've detailed previously, Just Walk Out uses computer vision, sensors and AI to let you walk into a store, sign in with an app, fill up your bags and leave without the need to join a checkout line. On top of using the tech in its own Go and Fresh stores, Amazon signed a deal last year to license its technology to third-party retailers.

Amazon (AMZN) has introduced shopping carts that make it faster and more convenient to shop by automatically tracking the items put in the cart, enabling consumers to eliminate the checkout line. The new Dash Carts will first be featured at Amazon's Woodland Hills, California, grocery store, set to open this year. To use the Dash Carts, shoppers will need to have an Amazon account and a smartphone. Shoppers simply scan a QR code located within the Amazon app to begin loading items into the cart. The Smart Cart is fitted with computer vision algorithms and sensor fusion to recognize merchandise that is put into the cart.

Amazon has created a smart shopping cart that knows what you're selecting and can charge you for it without a cashier. It's called the "Amazon Dash Cart" and the idea is to make "a quick grocery trip even quicker by allowing you to skip the checkout line," the e-commerce giant said in a post on Tuesday. The Dash Cart largely looks like a typical shopping cart, only bulkier at the bottom. Patrons will use their Amazon account's unique QR code to sign-in to the cart, according to a video the company posted on its website. Then you add your shopping bags to the cart and proceed to shop around the store.

Identifying different foods on a tray can be a non-trivial task (Image source: Chris A. Tweten on Unsplash) Unfortunately, we don't always have sufficient time to enjoy a leisurely lunchtime meal. Suppose some of your workmates invite you to join them for lunch at a local fast-food restaurant. You all typically have a limited amount of time for your lunchtime break and you need to use this time wisely and efficiently. First, you have to get to the restaurant, either by walking or perhaps by taking a short drive. When you reach the restaurant, you have to select your food, pay for it, and eat it.

From cashierless Amazon Go stores to Walmart's self-driving vans for food drop-offs, tech is revolutionizing grocery shopping with an emphasis on speed and convenience. Now a lesser-known startup is entering the fray with its AI-powered shopping carts that could put an end to bothersome checkout lines at your local store. Equipped with an interactive display and card swiper, the Caper smart shopping cart lets you scan an item's barcode as you shop and pay before you leave. It's already available in two stores in New York, claims the company, which lists Key Food Fresh, Met Fresh and Pioneer Supermarkets as its retail partners on its website. But Caper will need a bigger team-up if it wants to go the distance. For now, it's marketing its smart cart as a more affordable, scalable solution for businesses looking to get in on the autonomous shopping action.

Walmart's membership-only retail warehouse chain is prepping to take on Amazon with the launch of a new concept store that has no cashiers or registers. A Sam's Club in Dallas, Texas is testing a new store format where shoppers use an app to buy groceries without the need to stand in a checkout line, according to CNBC. The concept closely mirrors Amazon Go, the cashier-less stores launched last year by the internet giant. A Sam's Club in Dallas, Texas is testing a new store format where shoppers use an app to buy groceries without the need to stand in a checkout line or deal with cashiers The 32,000-square-foot store is smaller than other Sam's Club locations and mostly features basic food items like produce, meat and alcohol. For now, it's rolling out for select customers, but the firm expects to expand soon, CNBC said.

Cyber retail giant Amazon is planning to add a checking-account-like product to their platform. Practically all of its profits come from its cloud computing division, Amazon Web Services (AWS). Beyond that, Amazon has a growing advertising business, offers a variety of services to third-party merchants, and runs one of the biggest streaming video services in the world. Amazon is still concentrated on various retail efforts as well. It recently opened its Amazon Go store to the public in Seattle, and it reportedly plans to open up to six more across the country this year.

We're all only about ten years away from sauntering into stores, grabbing whatever it is we want, then quick-stepping out like we stole it. It'll be possible because many shops will be ringed with machine vision-enabling cameras and sensors, that keep tabs on what you take while inside and then charge it to the corresponding app as you leave. Analysts say the big shift is being ushered in by retailers trying to stave off the online shopping explosion. People tend to cite crowds and lines as reasons they avoid stores, so the hope is that tech will be the savior of the remaining brick and mortar mainstays. But while that checkout change might thrill some customers, it'll also dramatically change employment for low-skilled retail jobs and comes with a host of privacy concerns.
