See every featurePOS Cart Attributes adds cart and item attribute capture to Point of Sale—no backend. A smart-grid tile sets order-level attributes from an admin key list. The line-item action sets per-item values (e.g. serial numbers) from a separate list. Both use the same pick-key, enter-value flow. Curate keys in Shop metafields so every device stays in sync—no per-device setup.
