Amazon is expected to begin shipping on Thursday the first tablets using the voice-activated Siri technology that the online retailer has been using to sell its own items for months.

The tablets, which will be sold as Amazon Echo Dot devices, will be available for pre-order through Amazon and will cost $159.99 each.

The new devices will also be compatible with Amazon’s own cloud-based e-commerce platform called Amazon Go.

Amazon Go will let users pay for products by scanning their credit card information and shipping details, and will allow them to make purchases using Amazon’s e-wallet service.
