1. Project Overview

In 2024, a private investor launched a network of sampling vending machines with a total of 18 units deployed across Hanoi, Da Nang, and Ho Chi Minh City. This is a completely new model in Vietnam, combining automated vending technology with smart product marketing strategies, and has delivered results beyond expectations.

2. How Do Sampling Vending Machines Work?

Unlike traditional vending machines, sampling vending machines are specifically designed to distribute trial-size samples of consumer products such as:

• Cosmetics: skincare cream, perfume, mini lipsticks…
• Food & beverages: energy drinks, new snacks, instant cereals…
• Small household items: toothbrushes, razors, innovative packaging…

Operation:
- Users interact directly via a touchscreen, scan a QR code or enter a promo code to receive a sample.
- You can configure the machine to:
+ Distribute samples 100% free of charge, or
+ Charge a small fee (2,000–10,000 VND/sample) to increase perceived value.
- The system records data such as: pickup time, location, number of samples distributed, and customer information (if registration is enabled).

3. Trial Product Distribution Model in 3 Major Cities

Hanoi: 6 machines installed in high-rise office buildings and shopping centers (e.g. Times City, Keangnam, The Garden…).
Ho Chi Minh City: 8 machines placed on university campuses, hospitals, and high-end residential areas.
Da Nang: 4 machines piloted at the airport, administrative centers, and office buildings.

➡ Locations were chosen based on three key criteria: high foot traffic – right target audience – easy user interaction.

4. Benefits of Sampling Vending Machines

For Investors:

- Dual revenue streams: from sample fees + leasing ad space to brands.
- Easily scalable thanks to automated operation and low staffing needs.
- Customer insight collection for brand partners (e.g. gender, trial time, conversion to full purchase…).

For Brands:

- Targeted sample distribution to real potential users instead of mass handouts.
- Increased engagement and brand recall through personalized experiences.
- Measurable campaign performance via real-time analytics software.

5. Why Should You Invest in Sampling Vending Machines?

1. Modern Marketing Trend

Traditional sampling methods (handouts, supermarket stands) are becoming less effective due to poor measurability and high costs. Sampling via vending machines offers a smarter solution — cost-efficient, data-driven, flexible, and targeted.

2. Stable Profit – Low Operational Costs

- Revenue comes from sample sales, screen advertising, and brand partnerships.
- Each machine can generate 10–20 million VND/month, depending on its location and partner brands.

3. Nationwide Sampling Network

- Easily scalable into a chain covering North – Central – South regions of Vietnam.
- Perfect for brands launching nationwide marketing campaigns with controlled budget and high effectiveness.

Conclusion

After nearly a year in operation, the 18-unit sampling vending machine network has proven to be efficient, flexible, and commercially viable in the context of modern marketing.
This model not only serves as an innovative product distribution channel, but also opens up a promising revenue stream for individual investors and product distributors alike.
