Amazon has announced a new version of its smart shopping cart. The new Dash Cart can transport more groceries and includes new features. Amazon says the latest version can carry four grocery bags, up from two previously, and has dedicated shelves for delicate and oversized items. The latest version is also weather-resistant so you can take it to your car.

As before, the cart will automatically weigh produce and keep a real-time tally of all the food you buy. Amazon has tweaked the software on the touchscreen to display images of nearby fresh fruit and produce. The company's software will now also do a better job of keeping track of where the cart is in stores and notifying you of deals. Lastly, the latest version has a bigger battery, which should translate into the new Dash Cart being more frequently available for customers to use.

Speaking of availability, Amazon is finally bringing the Dash Cart to Whole Foods, starting with the chain’s Westford, Massachusetts location and expanding to “a few additional” stores in the coming months. Previously, Dash Carts were only available at the company’s Amazon Fresh grocery stores, of which there are only about two dozen locations in the US at the moment.

Once Dash Carts arrive at your local Whole Foods, you can start using them by scanning the QR code you find on each one in the Amazon or Whole Foods Market apps. As you find items you want to buy, you scan them with one of the cameras near the cart's handlebar. Once you’re done shopping, you exit the store through the dedicated Dash Cart lane. Amazon will automatically bill the credit card associated with your account, and you’ll get an emailed receipt after leaving the store.
