Digital vs. Physical Buzzers: The End of the Plastic Coaster
Key Insights
- •Coaster pagers get dropped, walked off with, and worn out, so a fleet is a cost you keep paying — you're always replacing a few.
- •They only work within radio range of the base station, so a guest who wanders too far misses the buzz the pager was meant to give them.
- •A pager only ever costs you money. It lights up and that's it — there's no way to put a special or an offer in front of the person holding it.
- •Move the buzzer onto the guest's own phone and that same alert screen becomes something you can actually sell from.
For two decades, the flashing, vibrating plastic coaster was the gold standard for managing waiting lines. Today, it represents an unnecessary operational anchor that actively restricts the customer experience and bleeds revenue.
The cost that never stops
Coaster pagers get dropped, sat on, and walked off with, so the day-one price tag is only the start. Commercial systems aren't cheap: a premium kit from a supplier like JTECH or LRS can run past $1,000 for a base station and around twenty coasters, while budget kits start lower — a 20-pager Retekess set is advertised around $219 (supplier listings, 2026).
Whatever you paid up front, the fleet keeps costing you: every coaster that leaves in a coat pocket has to be replaced, and the premium coasters most sit-down venues use typically run $40–$70 each to swap out. With a phone-based system like Bzz, there's no fleet to lose — the "pager" is the phone the guest already walked in with — so that replacement cost simply goes away.
The range problem
A coaster only works within radio range of its base station, which ties the guest to a tight circle around the host stand. That's the opposite of what a pager is meant to do: instead of freeing people up, it quietly herds them back into an already-packed doorway so they don't miss the buzz.
Digital trackers use cellular networks. A customer can register at a food truck or clinic and wait blocks away to find shade, or await their slot in the comfort of their car. They receive live countdowns wherever they are.
What you gain by moving the buzzer to the phone
No hardware to buy or charge
No upfront fleet, no bulky charging docks, no transmitter to mount — you start with the phones guests already carry.
Wait anywhere
Guests aren't tethered to a radio range around the host stand. They can sit in the car or browse next door and still get the buzz.
A screen you can sell from
Show a menu preview, an upgrade, or a quick feedback prompt while the customer is already looking at their status — something a puck can never do.
Contactless check-in
A shared coaster passes from hand to hand all day; a guest's own phone doesn't. Some venues simply prefer to keep check-in hands-off.
The bit a coaster can't do
Here's the real difference, though, and it's not about cost. A coaster does exactly one thing: it lights up and buzzes. That's the whole of it.
Move the buzz onto the guest's phone and you get something a puck never could — a screen the customer is actively watching while they wait. That turns a dumb signal into a place to sell. A coaster just tells someone to come back; the phone can shape what they order when they do.
