ROI and Cost-Benefit Analysis

The return on investment analysis shows that, although the initial cost of hotel étiquettes électroniques for buffets is higher than paper solutions, the benefits become evident in the medium term.

This system eliminates several recurring operational costs, such as printing materials, labour time associated with manual label updates, and errors that often generate waste. Taken together, these factors represent a significant reduction in annual operating expenses.

In addition, automation contributes to greater efficiency, consistency in displayed information and a better customer experience.

Overall, the investment tends to be recovered within a relatively short period, subsequently generating continuous and sustained savings over time.

Additionally, intangible but relevant benefits:

• Reduction in working hours spent on low-value tasks
• Lower error rate and consequent reduction in waste
• Autonomy of labels (several years without battery replacement)
• Enhancement of guest experience with positive impact on reviews
• Enhancement of guest experience with positive impact on online reviews (1 additional star can increase revenue by 5–9% according to Cornell University studies)
• Reduction of complaints related to allergens or incorrect information
• Contribution to sustainability and quality certifications

Hotel Étiquettes électroniques: More Than Dish Identification

The solution implemented at Vila Galé demonstrates that hotel étiquettes électroniques go beyond simply replacing paper with screens. It is an integrated digital communication system that:

• Automates processes through intelligent rules
• Centralises management of multiple properties
• Increases operational flexibility with immediate response capability
• Improves customer experience with clear and multilingual information
• Reduces environmental impact by eliminating paper waste

FAQ – Frequently Asked Questions about Digital Labels in Hotels

How long does the battery of digital labels last?

The e‑paper digital labels used by the Vila Galé Group have batteries lasting up to 5 years under normal use (if updated once per day). E‑paper technology consumes energy only when the image is refreshed, not during static display, which enables this exceptional durability. The batteries can be easily replaced by the hotel’s own staff without the need for a specialised technician.

Do digital labels withstand restaurant environments (humidity, temperature, splashes)?

Yes. The digital labels were specifically developed for food service environments. They are resistant to temperature variations typical of buffets (hot and cold food), high humidity, and have appropriate protection ratings. In the case of Vila Galé, after months of intensive use, no failures related to environmental conditions were recorded.

Is it necessary to have Wi‑Fi throughout the entire buffet area?

No. Our labels communicate via low‑energy Bluetooth (BLE) with a central gateway connected to the network. Only the gateway requires network connectivity (Wi‑Fi or Ethernet). The labels themselves do not need direct Wi‑Fi, which greatly simplifies the required infrastructure.

How long does it take to update the labels when I make a change?

Updates are practically instantaneous. When the hotel team makes a change in World VDS (for example, updating a dish or activating an urgent playlist), the information is sent within 2–5 seconds to all affected labels. This allows rapid response to unexpected situations.

What if a label runs out of battery during service?

The labels have low‑battery indicators in the World VDS system, alerting staff weeks in advance when autonomy is nearing its end. Additionally, even with a completely depleted battery, the last displayed information remains visible on the e‑paper label (it does not disappear), ensuring service continuity until the battery is replaced.

Can I use the labels for purposes other than identifying dishes?

Yes. The World VDS system allows labels to be programmed for multiple uses:

• Outside buffet hours: display the hotel logo, promotions, or institutional messages
• Special promotions: highlight special days, feature specific dishes, or showcase chef’s specials
• Nutritional information: in addition to allergens, display calories and nutritional values
• Signage: use larger labels for directional or informational signage in the restaurant

Conclusion: The Future of Hotel Management Is Digital

The case study of the Vila Galé Group with digital labels for buffets by Amplitude Net represents a significant transformation in how hotels manage their food service operations.

The replacement of manual processes with intelligent automation, combined with operational flexibility and environmental sustainability, demonstrates that digitalisation is not just a trend but a competitive necessity for contemporary hospitality.

With this project, Vila Galé strengthens its position as a reference in technological innovation in Portuguese hospitality, proving that investing in digital labels for restaurants delivers tangible returns in efficiency, sustainability, and guest experience.
