Amazon Go /Big Basket Smart Machine - Tech Analysis

Amazon Go

• QR Code for user account linking
• Pick items, Auto detected
• Multiple validation points (Video Object Detection, Shelf Weight sensor-based confirmation, RFID reads etc)
• Multiple RFID readers to capture item movement across ISLEs

Cons

• Massive surveillance 
• Real-time computation

IMO, Big Basket Smart Machine is also similar to the implementation

• QR Code for user account linking
• Pick and Buy
• Mobile App integration 
• Weight Sensors used to detect Shelf Item Quantity
• Unique Items in each row. It is not mixed

Since its a standalone machine, it will not need any tracking with RFID / Video camera. Only Weight sensors sufficient and it is a single person operated at a time.

Happy Learning!!!
