Not everything in kids' rentals fits into "a counter reading" or "a wristband at the entrance." A trampoline sold by jumps with no fixed duration, an electric car that carries one child at a time — RentOS has a separate mode for that, "Launches": not a reading, not time spent, but the actual fact of a ride, recorded the moment it happens.

Untimed — a Digital Version of the Tally-Mark Notebook
The simplest rate is literally called that in the interface — "Untimed": one tap on the asset — one ride recorded, instantly. The employee picks a payment method, and that's it — no readings to enter, nothing to remember until the end of the shift. It's essentially a direct digital replacement for the paper notebook with tally marks that many points still use by hand — except this "notebook" never gets lost, never tears, and tallies itself up.
Timed — When a Ride Is Limited by Time
The second option is "Timed": the rate has several duration-and-price options, the employee picks the right one at the start, and the asset's tile shows a countdown. 30 seconds before it runs out, the tile already starts blinking — the warning comes ahead of time, not at the last moment. When time's up, the tile signals with sound, vibration, and pulsing — even if the employee is looking at a different screen of the app at that moment: the warning about a ride ending pops up no matter where the employee currently is, whether it's "Launches" or "Stays" — both modes share the same timer engine.
One Asset, One Ride at a Time — Enforced by the Server
An electric car physically can't carry two children at once — and RentOS won't let you start a new ride on an asset while the previous one is still open. This isn't a hint in the interface you can ignore — the server will reject the attempt to start if the asset already has an open ride.
The 30 Seconds That Stop People From Cheating the Till
Timed rates have a detail that's hard to invent unless you've run into real fraud at a rental point: there's a 30-second window between stopping a ride and confirming the payment method. This protects against a specific scheme: stopping the timer early, while the child is still riding, to record a cheaper, shorter ride on paper and pocket the difference. If the payment isn't confirmed within those 30 seconds, the ride automatically goes back to "in progress" — you can't game the system by pausing it.
The Till — Per Asset, With a Live "Difference"
At results submission, the calculated revenue for "Launches" is shown separately for each asset, not as one lump sum for the whole zone — and right next to it you immediately see the gap between that and what the employee actually put in as cash. There are quick-fill buttons with the expected amount, but they're just a hint, not an auto-filled number: the real cash recount stays independent of the calculation — otherwise the reconciliation loses its point. And as long as even one timed ride is still running, results can't be submitted for the zone — the system will state exactly how many rides need to be finished first.
Who It's For
"Launches" is for anything sold as a single ride that doesn't fit a running counter or an entry wristband: trampolines "by jump," electric cars, go-karts, rides with fixed or flexible ride time. It's the same reliable timer engine as "Stays" — so if a point has, say, trampolines billed by ride alongside a separate play room billed by time, both formats run on the same proven mechanics, not on two different systems inside one dashboard.
