Circumtec
Circumtec cashless card readers — the practical MDB retrofit
Circumtec — also written Crimtec — is the pragmatic cashless choice when you have good site locations but older MDB machines that were never sold with card payment in mind. It wires into the existing loom and gets you off coin without replacing hardware.

Circumtec — often written Crimtec — is the pragmatic choice when you have acquired good site locations but the machines on them are older MDB units that were never sold with cashless in mind. The module is compact, wires into the existing loom, and gives the customer a simple tap-or-insert card experience without you replacing the machine.
Reporting is deliberately lighter than a full telemetry platform: sales counts, cash-versus-card split and basic fault flags, which is usually all you need on a route where you are already visiting for stock. Setup is commonly under an hour per machine, and the lower landed cost of roughly $450–$700 means the payback window on a modest site can be a single quarter.
If your plan is to run a compact metropolitan route in Sydney, Melbourne, Brisbane, Perth or Adelaide with machines you already own, Circumtec is the cheapest credible way to stop taking coins.
- Retrofitting older MDB machines rather than replacing them
- Small routes where hardware cost matters more than analytics
- Operators testing a new site before investing in new equipment
Why a retrofit beats replacing the machine
A serviceable snack machine with a healthy compressor and a clean cabinet has years of earning left in it. Replacing it to gain card payment costs five figures; fitting a Circumtec module costs a few hundred dollars and takes under an hour, and the customer experience at the machine front is identical — they tap and the product drops.
That maths matters most when you have just bought a verified site location and want the machine earning this month rather than next quarter.
The reporting you actually get
Circumtec gives you sales counts, the cash-versus-card split and basic fault or connectivity flags. It is not a route-management platform and does not pretend to be.
On a compact route where you are already on site every week or two for stock, that is generally enough: you can see whether a site is performing, whether cashless has grown the take, and whether a machine has gone quiet. If you later scale past thirty machines and drive time becomes your biggest cost, that is the point to look at a full telemetry platform.
Fit, compatibility and install
Any machine with an MDB harness is a candidate — the module presents to the machine as a payment device on the same loom the coin mech uses. Installs are commonly done during a normal stock run rather than a dedicated trip.
Check mobile coverage before you commit on basement, plant-room and steel-clad warehouse sites; a cashless module with no signal is a very expensive coin mech.

Circumtec questions Australian operators ask
Will a Circumtec module work on my older vending machine?
Almost certainly, provided the machine has an MDB harness — that covers most snack, drink and combination machines built from the mid-1990s onward. Pre-MDB or proprietary controllers are usually cheaper to replace than adapt.
Is Circumtec the same as Crimtec?
Yes — Australian operators use both spellings for the same cashless payment hardware. We use Circumtec as the brand name and keep Crimtec alongside it so searches for either land on the right information.
How much does a Circumtec cashless retrofit cost?
Roughly $450–$700 landed per machine plus a modest monthly plan and merchant rate near 5–6%. On a machine turning over $700–$900 a month, payback on the hardware is commonly inside a single quarter.
