Grocery scan vs EMS alert
Food allergy?
Scan barcodes free → build profile → print wallet QR ($4.99). Hidden ingredient keywords on every label.
Beyond food?
When the risk is meds EMS gives — not peanuts in the pantry. Build an EMS profile → wear it on a shirt sleeve.
Same QR engine
Both lanes use the same profile builder and short links. Different defaults, different marketing — same scan-to-responder view.
