DOOH (Digital Out-of-Home) on smart vending machines is redefining outdoor advertising in Vietnam. Instead of "display and hope" like traditional billboards or LCD screens, Dropfoods' DOOH Retail Media platform enables brands to measure the entire journey — from ad display, to interaction, to actual purchases at the point of sale. This article explains what DOOH on Smart Vending is, the two advertising product types, the 3-tier measurement framework, and the 300+ machine network across Ho Chi Minh City.

1. DOOH on Smart Vending — How is it different from traditional outdoor ads?

DOOH (Digital Out-of-Home) refers to digital advertising displayed in public spaces — commonly seen on LED billboards, LCD screens at airports, shopping malls, or elevators. However, most traditional DOOH platforms can only measure the number of video plays (impressions), without knowing who actually watched, interacted, or made a purchase after seeing the ad.

DOOH on Dropfoods Smart Vending Machines differs in 3 fundamental ways:

  • Point-of-Purchase: Ads are displayed right where consumers make buying decisions — on the LCD screen of the vending machine. The distance from "seeing the ad" to "making a purchase" is just one tap.
  • Non-skippable & Captive Audience: 6–10 second video ads play continuously for 15 hours/day (7AM–10PM), 100% unskippable. Buyers stand in front of the machine for 15–45 seconds while selecting products — this is precious "captive attention" time.
  • Closed-Loop Measurement: For Type A products, Dropfoods can precisely measure: which videos played, who interacted, and how many purchase transactions occurred — directly on the same device, at the same moment.

💡 The Core Differentiator

Billboards give you impressions. Facebook gives you clicks. Dropfoods gives you Verified Purchases — proof that your brand was not just seen, but directly generated purchase transactions at the point of sale.

2. Two DOOH Product Types: Type A (Closed-Loop) vs Type B (Interactive)

Each type serves a different group of brands, with distinct measurement methods and value propositions.

Closed-Loop

Type A: DOOH + Product on Machine

For: Brands WITH products sold on the machine (beverages, snacks, dairy, food...)

  • Video ads + Product placement on machine
  • Measurement: D-Spots → Interacted → Verified Purchases
  • Closed-loop: View → Interact → Purchase — all measurable
  • Crystal-clear ROI: know exactly how many purchases followed an ad view
Interactive

Type B: Pure DOOH (Ads + Interaction)

For: Brands WITHOUT products on the machine (banks, insurance, automotive, apps...)

  • Video ads + Interaction (games, surveys, QR, sampling)
  • Measurement: D-Spots → Interacted (clicks, game plays, QR scans)
  • Lead collection: phone numbers, emails, survey data
  • Brand activation at point of sale
Comparison Type A — Closed-Loop Type B — Interactive
Target Brands with products on the machine Brands without products on the machine
Core Value Ads + Product placement + Purchase data Ads + Engagement + Lead data
Top Metric Verified Purchases (100% VCR) Interactions (game, survey, QR)
Examples Beverages, snacks, coffee, dairy Banks, insurance, automotive, apps

3. The 3-Tier Measurement Framework: D-Spots → Interacted → Verified Purchases

From "video played" to "actual purchase" — each tier measures a different level of engagement.

🥉 Tier 1
D-Spots
Video plays in loop
(ambient, passive)
🥈 Tier 2
Interacted
Ad clicks, games,
surveys, QR scans
🥇 Tier 3
Verified Purchases
Watched video + bought
(Type A only)
Metric Meaning Applies To
🥉 D-Spots Video/banner played in the loop cycle — with or without a direct viewer. Equivalent to "impressions" in traditional DOOH. Type A + B
🥈 Interacted User actively engages: clicks the ad, plays a game, answers a survey, or scans a QR code. Type A + B
🥇 Verified Purchases Video plays directly when a buyer selects the product → watches the full video → completes the purchase. 100% Video Completion Rate. This metric is unique to Dropfoods. Type A Only

📊 Real Case Study — 3-Tier Measurement in Action

In a Type A campaign spanning 48 days across 100+ machines, Dropfoods recorded:

  • 🥉 5,466,932 D-Spots — continuous video play 15h/day, unskippable
  • 🥈 542 Interacted — direct clicks on the advertisement
  • 🥇 7,040 Verified Purchases — watched video then purchased right at the machine
  • Cost per Purchase: only 3,636 VND (~$0.15) — 14–82× cheaper than Facebook, Google, YouTube
