Free WiFi as a Marketing Channel
Every restaurant offers free WiFi. Very few use it as a marketing tool. With a simple captive portal setup, your free WiFi becomes a customer data collection machine that builds your marketing list automatically.
A captive portal is the login page customers see when they connect to your WiFi. Instead of open access, you require them to enter their phone number or email before getting internet access. This opt-in gives you permission to market to them.
Setting Up WiFi Marketing
What you need:
The customer experience:
Privacy and consent: Include a brief consent notice: "By connecting, you agree to receive occasional offers and updates from [Restaurant Name]. Unsubscribe anytime." This keeps you compliant and respectful.
Most restaurants collect 20-50 new phone numbers per day through WiFi marketing — that is 600-1,500 new contacts per month for your WhatsApp marketing list.
Using Collected Data Effectively
WhatsApp broadcasts: Send weekly specials, festival offers, and new menu items to your WiFi-collected numbers. Include your Restrofi ordering link for direct ordering.
Personalized offers: Track how often a customer connects (returning customer) vs first time. Send different messages to each group: welcome offers for new visitors, loyalty rewards for regulars.
Win-back campaigns: If a customer hasn't connected to your WiFi in 30 days, send a "We miss you" message with a special offer.
Peak-hour management: WiFi connection data shows exactly when customers visit. Use this to plan staffing, prep, and promotions for slower periods.
Combining WiFi data with Restrofi ordering: When customers who logged into WiFi also order through Restrofi's QR system, you get a complete picture: who they are (WiFi data) + what they ordered (Restrofi data). This enables powerful personalized marketing that drives repeat visits and higher spending.
WiFi marketing costs ₹5,000-15,000 one-time for a marketing router and produces ongoing value for years. Combined with QR ordering through Restrofi, it transforms anonymous diners into known, marketable contacts.
