Add cashless to your MDB machines.
- Tap, chip, or swipe on any MDB-capable machine
- Runs alongside the coin and bill acceptors already on it
- Every card vend tied to the real product behind the slot
- The same reader runs your self-serve car wash
Dryline VMS puts every machine on one screen. See each slot, fill it by scanning a barcode, and add card payments to your MDB-capable machines with Rain Pay — all on the same MonsoonOS platform that runs your wash.

You see the real machine front, not a list of numbers. Every slot shows its product, price, and how full it is. Low and empty slots turn copper, and anything missing a price or a barcode gets flagged before it costs you a sale.


Build a machine’s whole layout by scanning barcodes — each product drops straight into the slot. Save a layout as a template and reuse it across machines. Every change shows in plain English before it’s live, and you can roll back to any earlier version.
Every card vend is tied to the real product behind the slot, so your top sellers, slow movers, and busiest machines are just there — today, last 7, or last 30 days. Export any period to CSV when you need the numbers elsewhere.

Rain Pay is an MDB cashless reader for unattended machines. If a machine is MDB-capable, it adds tap, chip, and swipe alongside the coin and bill acceptors already on it — and the same reader can run your car wash. Wash, vending, and tips all settle on one ledger.
Rain Pay connects over MDB, so the machine needs an MDB port already — there’s no retrofit kit for machines without one. We confirm fit before quoting.
Every slot shows its product, price, and how full it is on the real machine front. Edit it with a tap, not by hunting through a list of numbers.
Point your phone at a barcode and the product drops into the slot. Set up a whole machine in a couple of minutes and reuse layouts as templates.
See every change in plain English before you publish it, and roll back to an earlier setup any time. Nothing goes out that you did not read first.
An honest running count for every machine, with each card vend tied to the real product, so top sellers and slow movers are just there — not guessed at.
