Food Trucks Don't Have Room for a Printed Menu Board
A food truck runs on limited space and a line that needs to move. A big printed board eats space you don't have and can't change fast enough for how a truck actually operates.
Space is the truck's scarcest resource
Every square foot of a truck's exterior competes for branding, a window, and a menu board large enough to read from a line. A QR code takes up a sticker's worth of space and does the same job as a full board.
Daily specials are the whole point of a truck menu
Trucks live on rotating specials based on what's fresh or what sold out yesterday. Repainting or reprinting a board for that is impractical - most trucks end up with a handwritten sign taped on, which looks improvised. A digital menu updates in seconds and always looks intentional.
A faster-moving line is more revenue per hour
Customers who can browse the full menu on their phone while still in line - instead of squinting at a board and holding up the person behind them - order faster once they reach the window.
No signage to weatherproof or replace
Printed signage on a truck takes a beating from sun, rain, and constant handling. A QR sticker is cheap and simple to replace; a full printed board is not.
Set up once, use it at every location
Same QR code works whether you're parked downtown or at a weekend market - one setup that travels with the truck.
