Engineering first. For thirty years.

Turkey's first homegrown Mobitex product

Turkey did not get mobile packet data until GPRS opened in March 2001. We were already moving wireless packet data from the field in 1998, on Mobitex — Ericsson's packet-data network — and Mobicom, the operator, gave us an award for the first homegrown product built on it. That is remote telemetry, a quarter-century ago.

A reporter looking for coins, and the machine that didn't need them

At the Bilişim '99 fair a journalist stood in front of a drinks machine, hunting through his pockets for change, before noticing he could pay by card. One of our founders showed him how; the queue that formed behind him made the photograph. He filed the story that evening — and it is the earliest dated, independent record that names us, written the same week the machine went to work.

Our own website already listed the whole platform

You can still read it on the Internet Archive. By December 2000 our site already listed what the platform does now: remote price change, promotions, sales and inventory control, automated and remote control of functions, routing, GPS — and card acceptance across smart cards, proximity (Mifare, Hitag), magnetic stripe, i-Button and U-Key. On the same page, the machines were never only vending: "we control electromechanical devices such as vending machines, taximeters, parking meters, turnstiles, doors, gasoline pumps." And it wasn't just talk: with Turkcell we ran GSM/SMS turnstiles that admitted visitors to the Bilişim 2000 fair, and built GPS fleet tracking and biometric access control alongside the vending work. Two years later the site added the line that still sums it up — remotely control your EXISTING vending machines.

A real-time kernel of our own, under four kilobytes

Designing the board is half the job; something has to run on it. We wrote that too. By late 2000 DMS-OS — our own real-time operating system — was in beta and published with its own spec sheet, aimed at third-party developers who wanted to build on our hardware. Read the numbers with an 8-bit microcontroller in mind: a preemptive kernel with round-robin scheduling, configurable while running, in under four kilobytes of ROM. It later carried across to the 32-bit generation of the same product line. This is the part of the work customers never see and competitors cannot copy quickly.

The first card-paying vending machines in Turkey, in the field

For Pepsi-Cola, we made vending machines accept VISA/MasterCard over a wireless network — no phone line — with sales buffered on the machine and settled with the bank. The independent trade press reported it as a Turkish first, engineered end to end by Turkish engineers.

Our name, printed on the machine itself

This wasn't a back-office contract nobody could see. The usage sticker on the Pepsi card-payment machines — the one a customer reads while paying, complete with WorldCard and loyalty-point support on Yapı Kredi Bankası's rails — put it in plain type at the bottom.

We named QuadC

Our cloud reporting platform has carried the same name, QuadC, since 2005. The architecture we drew then — an in-machine unit over GSM/GPRS to a country server and a .NET application, feeding filling, service and sales reporting to operators — is the same backbone the platform runs on today. Not a rebrand; a continuous line.

The customer, ten years on, said it themselves

This was never a one-off pilot. A decade after the first deployment, Pepsi Bottling Group's on-site consumption director put the relationship on record in the trade press — and named us.

On the city's own channel, in the field

You don't have to take our word for any of it. İstanbulkart's official channel — the operator of Istanbul's city card — filmed our payment device accepting İstanbulkart on İBB's Hamidiye water machines. Watch the screen just before the tap: it reads DMS Tech.
