  1. In a cashierless store, what do shelf weight sensors mainly contribute?
    • Identifying shoppers by their faces
    • Detecting when an item is lifted from or returned to a shelf
    • Printing receipts at the exit
    • Setting prices for each product
  2. Why are some shopping events sent to human reviewers?
    • The law requires a person to watch every transaction
    • Reviewers set the store's prices
    • Reviewers restock shelves remotely
    • The system's confidence about who took which item falls below a threshold, for example on a crowded shelf
  3. What did Amazon do with Just Walk Out in most of its US Amazon Fresh grocery stores in 2024?
    • Replaced it with Dash Cart smart carts
    • Added facial recognition to it
    • Expanded it to cover more aisles
    • Converted the stores to cash-only payment
  4. Which kind of store is generally the best fit for full camera-based checkout-free technology?
    • A large supermarket with lots of loose produce
    • A warehouse club selling bulk pallets
    • A small, busy shop with a limited product range, such as a stadium concession stand
    • A furniture showroom with made-to-order items
  5. Why does combining weight data with vision work better than either one alone?
    • Weight sensors can recognize product packaging
    • Cameras cannot see shelves at all
    • Different products can weigh the same and cameras can be blocked, so each signal covers the other's gaps
    • Combining them removes the need for camera calibration
  6. What role does the planogram play in identifying which item was taken?
    • It tells the system which product is supposed to sit on that shelf
    • It tracks shoppers' faces
    • It processes the payment
    • It sets the receipt format
  7. How do most cashierless systems track shoppers inside the store?
    • By scanning ID cards at every shelf
    • Through GPS on shoppers' phones
    • Through RFID tags worn by shoppers
    • As anonymous figures followed by overhead cameras, generally without facial recognition
  8. How can a family shopping together be handled?
    • Each person must enter with their own payment method
    • One payment account can cover several tracked people who entered together
    • Items passed between people are never charged
    • Groups must use a staffed register
