Homeowners usually call an electrician once or twice a year, often in urgent situations like sparking outlets or tripped breakers. When your electrician installs a new panel, they leave a card by the breaker box. Years later, when the homeowner needs to add a circuit for an EV charger, they can easily book you using that card—no marketplace fees or lead competition.Electrical work is rare but valuable, making repeat customers crucial. A single NFC card can lead to multiple jobs worth thousands over a decade, all from a $5 investment.

Garage doors break in predictable ways. Springs wear out. Openers fail. Tracks bend. And every time, homeowners panic because their car is trapped or their house is exposed. That panic makes them click the first paid ad—which costs you dearly.Your technician replaces the spring, leaves a card magnetically attached inside the garage. A few years later, the opener motor dies. Instead of searching, the homeowner taps the card and books you instantly. No competition. No Yelp reviews. Just immediate contact.Garage door companies see 30 to 40 percent return rates because doors require ongoing maintenance, spring replacements every few years, and periodic opener upgrades. One card install delivers years of direct access.
