How Businesses Use QR Observer
From vending machines to frozen food packaging — see how different businesses turn every product interaction into customer data, repeat revenue, and operational insight.
Vending Machine Operator
VendCo operates 50+ vending machines across New York — transit stations, offices, and gyms. Machines sell coffee, snacks, and bottled drinks. Their goals: reduce maintenance downtime, build a rewards email list, and understand which locations perform best.
They place two QR codes per machine: one on the machine body for service & loyalty, and one printed on every coffee cup for post-purchase engagement.

Frozen Food Producer
DumplingCo makes frozen dumplings in three flavors — pork, veggie, and shrimp. They sell direct-to-consumer via Shopify and in grocery stores like Whole Foods.
Their key insight: different QRs for different channels. DTC packaging pushes reorders. Grocery packaging captures new customers. Two QRs per SKU — 6 QRs for 3 products — each telling them exactly where engagement comes from.
