Dollars in seconds

Funds settle to the operator's own account at the quoted amount. No price risk, no Bitcoin held.

No chargebacks

Payment is final before the product drops. Nothing for your operators to fight.

Running on Custom Vending OMNI Series machines today.

Why integrators add it

Everyone ships the same card reader.

RFPs get won on price. Here is the line item nobody in unattended payments is competing on.

Same features as the next bid

Telemetry and card acceptance are table stakes a competitor matches by next quarter.

Flat attach revenue

Growing revenue on your installed base usually means a hardware cycle and a truck roll per endpoint.

Small-ticket fees

A fixed per-transaction fee eats a $1.75 vend before the percentage even applies. Your operators call you about it.

Chargebacks nobody wins

No signature, no cardholder present. A dispute on a $2.75 vend costs more to fight than to lose.

The math your reps take into the room

Cash is the most expensive tender in the machine.

Every dollar has to be collected, counted, transported and deposited, and some never arrive. Set the assumptions to a real operator in your base.

The operator

What each tender costs

IHL Group research on attended retail puts cash handling at 4.7% to 15.3% of cash revenue. Unattended operators carry a similar set of costs: route labor, counting, transport and downtime.
Effective rate on small tickets once the fixed fee is spread over a low average sale.

The riverArk side

Sets the operator's rate tier: 3.75% at the smallest volumes down to 1.00% above $1M a month.
An optional premium the paying customer covers. 2% recommended. Surcharge rules vary by state.

Your side

Up to 20%, 30% and 40% of riverArk net revenue. Maximums; your actual share is set in your agreement.
Their cash problem$0

spent every year handling cash across one operator's base. That's per endpoint, per year.

Your annual commission$0

Cost per $100 collected

Lower is better. Your assumptions, not riverArk's claims.

A virtual machine to transact against

A browser-based unattended machine at ark.riverArk.io/demo. Add an API key, machine ID and base URL, then run a real payment on real Lightning.

Runs beside the reader already there

A software addition, not a hardware swap. A second tender path is real uptime insurance when a reader fails.
