202 CMR 5.00 — Unit Pricing and Automated Retail Checkout Systems

Modernizes the Commonwealth's unit-pricing and price-accuracy regime for retailers using scanner and automated checkout (self-checkout, scan-and-go, RFID, AI vision) systems.

Who must comply: Retail food stores and any retailer operating 3 or more automated retail checkout systems (self-checkout, scan-and-go, AI vision, RFID).

What changes
  • All automated retail checkout systems in stores with 3+ registers must be examined by DOS (or a local sealer) at least every 24 months.
  • Unit-price displays must be legible from 3 feet, and included in any digital shelf display.
  • Scan-and-go and self-checkout systems must have a published accuracy rate and a staffed override.
