Nearly a year after it was promised, Amazon.com Inc.’s cashierless convenience store is slated to open to the public on Monday.

The new Amazon Go store, located in the base of Amazon’s main headquarters in Seattle, uses computer vision and machine-learning algorithms to track shoppers and charge them for what they select, thereby eliminating checkout counters.

Amazon announced the new Go store with fanfare in December 2016, and said it would open to the public in early 2017. The opening was delayed, however, as the technology proved more difficult to master than expected, with glitches occurring when too many people were in the store or were moving too quickly, The Wall Street Journal reported in March 2017.

Amazon Go’s technology uses cameras throughout the store to track shoppers once they are inside, though it doesn’t use facial recognition, Mr. Kumar said. A customer entering the store scans his or her phone and then becomes represented internally as a 3-D object to the system. Cameras also are pointed at the shelves to determine interactions with goods.
