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.


Build a machine’s whole layout by scanning barcodes: each product drops straight into the slot.
Top sellers, slow movers, and busiest machines, for today, the last 7 days, or the last 30.

Rain Pay is an MDB cashless reader for unattended machines.
The machine needs an MDB port already; there’s no retrofit kit for machines without one.
Dryline VMS has its own home at drylinevms.com, with a closer look at the planogram, scan-to-fill, and reporting.
Dryline VMS is the vending-management product from Cactus Wash Systems. It shows each machine as its real front, so every slot displays its product, price, and how full it is; you set a machine up by scanning barcodes, review changes in plain English before they go live, and see sales reporting tied to the real product behind each slot.
Dryline VMS is a Cactus Wash Systems product. It has its own site at drylinevms.com, but it is not a separate system to buy and reconcile: vending, wash, and tips share one platform, one login, and one ledger. A wash already on MonsoonOS turns vending on rather than standing up a second tool.
Yes, as long as the machine is MDB-capable. Rain Pay is an MDB cashless reader: it connects over the machine’s MDB port and adds tap, chip, and swipe alongside the coin and bill acceptors already on it.
A couple of minutes per machine. Instead of typing a list of numbers, you point your phone at each product’s barcode and it drops straight into the slot. Save a finished layout as a template and reuse it across machines, and roll back to any earlier version if you need to.
Vending sales, vends, and average vend at a glance, plus your top machines and top products, ranked, for today, the last 7, or the last 30 days. Export any period to CSV when you need the numbers elsewhere.
No, as long as they are MDB-capable, the common interface on modern vending machines. Dryline VMS is software plus a Rain Pay MDB reader for the machines you already run.
