The retail industry has undergone significant changes in the last ten years as a result of digitalization and technological advancement, and retailers have had to adapt by putting new business models and competitive strategies in place to meet the needs of their customers. The sector has been impacted by numerous new trends over the past few decades, including the emergence of supermarkets, the onset of e-commerce, the introduction of cashier-less stores, and more. In the latter, human involvement is minimized through the use of cameras, sensors, and self-shelving units. This is a new form of store that is entirely computer-based and digitalized. The introduction of Amazon Go, this growing idea was first introduced by Amazon, but other start-up businesses are quickly embracing the difficulty. The online retailer Amazon runs a chain of Amazon Go convenience stores in the United States and the United Kingdom. Nowadays, no one likes waiting in line at the register when shopping. Amazon developed automated Go stores that incorporate computer vision, deep learning algorithms, and sensor fusion for the buy, checkout, and payment phases involved in the retail transaction to automate this process. There are 32 stores in the United States as of March 2021 (both announced and established), and there are 15 in the United Kingdom. We shall examine every facet of this technology in this essay. This essay aims to examine customer knowledge of cashier-less stores and the applicability of many aspects of this novel type of store.
