 "description": "Yes, if expiry data is encoded, decoded and acted on by the POS. See the stop-sale chain and why Ambition 2027 alone does not require expiry processing.",
 "territory": "impl",
 "category": null,
 "direct_answer": "Yes, but the barcode does not stop the sale by itself. A retail 2D barcode can support expiry stop-sale when the required product and expiry data are encoded, the scanner and software decode that data and the retailer's host or POS applies a rule that blocks or flags the sale.",
