This project aims to improve on the company side costs of stores such as Amazon GO (cashier-less). I reduced the number of sensors and other electronic parts that are required to track customers and their purchases.
A combo of inclined shelves, distance sensors and NFC readers were used to achieve this.
The distance sensor and NFC reader communicate with a We-Mos D1 Mini to communicate their information to the server. Node.JS is used for server-side operations.
