Cashierless stores utilize artificial intelligence, computer vision, and IoT to facilitate seamless shopping without traditional checkouts. Customers enter using apps or biometrics, items are tracked in real-time, and payments occur automatically upon exit. This innovation, seen in Amazon Go and JD X-Mart, aims to improve convenience and efficiency.

Functionality relies on sensors for item detection, AI for virtual cart management, and cloud systems for transactions. Applications include urban stores and campuses, reducing wait times by up to 80%. The global market is projected to grow from USD 81.4 billion in 2024 to USD 962.6 billion by 2033, at a CAGR of 31.59%.
