Payment · One layer of the platform

Every way your customers want to pay.

Card, contactless, QR, meal cards, İstanbulkart and CSC closed-loop credit — accepted through one certified terminal and one platform. Payment is where DMS started in 1999; today it is one layer of the platform, not the product.

Four payment worlds, one integration

The same terminal speaks every scheme your customers carry — grouped here into the four families it actually integrates. On the machine that is the NEXGO UN20 (sold in Turkey as Pavo): one certified device, every brand below.

These are the manufacturer's published figures, not our measurements. We deploy the device; NEXGO builds and certifies it. Manufacturer's specification

Two of those rows are codes rather than numbers, and they are the ones that decide whether a machine can stand outdoors. Here is what they mean.

IP65

Dust-tight, and sealed against water jets

The first digit is dust: 6 is the top of the scale — no dust gets in at all, not merely 'enough to keep working'. The second is water: 5 means jets of water from any direction do not get in. That covers rain, wind-driven spray and a wash-down bay. It does not cover immersion — a rating of 7 or 8 would be needed for that, and this is not one.

IK10

Holds up in demanding public spaces, not just in an office

The impact scale runs to IK10 and this is the top of it: the front has to survive a 20-joule blow — roughly a five-kilo mass dropped onto it from 40 cm. That is not a laboratory nicety on an unattended machine. A terminal in a public corridor gets kicked, leaned on and occasionally attacked, and the screen is the part nobody can replace in the field.

−20 °C … +70 °C

It keeps working through a Turkish winter and a sealed cabinet in August

The low end matters for an unheated car park in Erzurum; the high end matters more than people expect, because the inside of a closed machine in direct sun runs far hotter than the air outside it. The touch panel is also specified to work through gloves — the same cold, seen from the hand that has to pay in it.

One honest limit: these ratings belong to the terminal, not to your finished machine. Protection is only as good as the cut-out it sits in and the gasket behind it — an IP65 device mounted badly in a machine door does not make the door IP65. Ask us how it is mounted, not just what the device is rated.

What the terminal accepts

One terminal, every method that matters

A single certified terminal on the machine takes the full range of payment types Turkish and international operators need — so a customer never walks away because their method was not supported.

Credit & debit — contact Chip-and-PIN card acceptance through the terminal's certified EMV stack.

Contactless Tap-to-pay for cards, phones and wearables — the default for fast self-service.

QR payments Bank QR has taken a serious share of Turkish payments in the last few years, and the flow runs this way: the customer picks QR on the terminal's screen, a code generated for that one transaction appears there, and they scan it with their own banking app. No card comes out of a wallet. That keeps the customer who carries no card — and the one who simply expects to pay by phone. There is also a version that is not a payment at all, and it runs in the opposite direction: an item paid for at the till and collected from the machine by QR — the till asks our server for a code scoped to that branch and that quantity, prints it on the receipt, and the machine reads it, validates it and dispenses. This runs today on Nestlé Professional's Coffee Corner machines.

Meal cards Multinet Up, Edenred, Pluxee (formerly Sodexo), Setcard, MetropolCard and Macellan — the meal-card ecosystem that drives Turkish vending.

İstanbulkart Closed-loop transit-card acceptance for machines sited across the city.

CSC — closed-loop credit Corporate entitlement: staff pay with the access card they already carry — any technology, from Mifare to proximity to magnetic (AnyID) — spending a credit their company defines. In production since 2010.

Since 1999

Payment is where the engineering started

DMS put the first online card payment on a vending machine in 1999. Every acceptance method since has been engineered in, not bought in — which is why payment on our platform behaves like part of the machine, not an add-on stuck to the side.

1999

First online card payment on a vending machine, on Yapı Kredi Bankası infrastructure.

2008

Contactless credit and debit acceptance, via Garanti Bankası.

2010

CSC — closed-loop corporate credit: staff buy from machines with the access card they already carry (AnyID), on a company-defined credit.

2010s

Akbil closed-loop payment — early experience with badge and prepaid schemes.

2015

Transit cards, İstanbulkart among them.

2018

The meal-card schemes, one after another: Setcard, then Multinet and Ticket/Edenred in 2019, Metropol in 2020.

2020

QR payments.

Twenty-five years of acceptance, every method engineered into the platform — not a reseller's terminal list.

Payment in context

Acceptance is one layer — not the whole story

Taking the payment is the easy part. The value is what sits around it: the same Hero Nexus that authorizes a card also drives the machine and reports telemetry, and QuadC reconciles every transaction across the fleet.

Payment on the same edge as control

Hero Nexus takes the payment and drives the vend or the PLC in one flow, so a paid transaction always maps to a real dispense.
Every transaction reconciled in the cloud

QuadC records each sale against its machine, method and time — revenue, refunds and reporting for the whole fleet in one place.
Offline-first acceptance

Payments authorize and vends complete even when the network drops, then reconcile the moment the link returns — nothing is lost.
Visible the moment it happens

Every payment lands in HERO with its machine, product, method and time. Sales, alarms and statistics open in a browser — from a phone in front of the machine or a desk in the office — with nothing to install.
What happens once it is fitted

Two separate things, and they should not be confused. First, substitution: where cash and card sit on the same machine, 80-90% of sales go through the card — we see that in our own dashboard. Second, growth: operators report that total sales at the same spot, on the same machine, rise as well — lately by 60-70%. That figure is theirs, not ours: we hold no data from the machine's cash-only period, so we do not measure the increase. Many operators eventually remove the coin mechanism and note validator altogether; nobody takes a thing out of a machine while it is still selling. Where cash stays, we keep servicing those units — so the decision remains yours.

Accept every method, on the machines you run

Tell us your machines and the methods your customers use. We will show you how the platform takes payment — and what it does with every transaction after. On machines that take card, 80-90% of payments go through it — and operators report that sales on the same machine grow as well. Whether cash stays is a decision you can make later, on your own numbers.
