What we do
Four core capabilities, one team
We take on the whole chain, from hardware design to the software running in the field. That keeps accountability in one place and removes the supplier risk in between.
Payment & campaign apps
Time and attendance, loyalty and vending machine payment applications, built to run on your own business rules — and without card data ever leaving the device.

Our own contactless terminals
Because we develop the hardware and the software together, communication between the device software and the server-side application never comes as a surprise.

Software solutions
Applications that follow your business rules
We do not store card data. The applications process your data on your own servers; the terminals only verify identity.
Time and attendance application
Employee attendance control driven by card taps.
- Entry / exit and shift records
- Leave, overtime and score tracking
- Per-employee detailed reports
- Authorisation and role management
Loyalty application
Turning customer retention into a programme you can measure.
- Membership, points and campaign management
- Customer segmentation
- Spending tracking and limits
- Integration and API support
Vending machine payment
Turning vending machines into contactless payment points.
- Contactless card payment
- Price and product configuration
- Sales and error reporting
- Remote device management
EFT POS application development
We write applications that run on third-party terminals
We develop the application you need on top of the terminals you already own, without changing their make or model. The work runs on the hardware vendor's ADK and SDKs, and card data never leaves the device.
EMV banking applications
For banks and acquiring merchants
- Experience developing applications at EMV L2 level
- Chip and contactless card transaction flows
- PIN entry, secure keypad, SAM and key management
- Online and offline authorisation, bank–acquirer integration
- Technical support during L3 certification testing
- Branded screen, menu and workflow design
Closed-loop and loyalty applications
Non-banking — no EMV required
- Loyalty and points programmes, campaign management
- Closed-loop prepaid wallets: campuses, public transport, municipalities, corporate canteens
- NFC / MIFARE reading, balance and counter stored on the card
- Kiosks, vending, turnstiles, canteens and access control
- Offline, online and hybrid operating modes
- Shorter time to market, since no certification is required
Banking work requires certification and security auditing; closed-loop work requires flexibility and speed. They are different disciplines — and we deliver both from the same team.
ADK / SDK integration
The application is written against the terminal vendor's development kits and verified on the device.
Branded interface
Terminal screen, menu structure and workflows designed to your brand identity.
Secure transactions
Payment steps are controlled on the device with DES / 3DES encryption and SAM security support.
Pilot and field support
Controlled rollout, training and technical support after go-live.
Innovative IoT projects
We make the physical world measurable
We design every layer together, from the sensing device to the cloud interface, so clients receive a system shaped around the need — not an off-the-shelf product.
Infrastructure & energy monitoring
Regular meter data collection, anomaly detection and reporting.
Fleet & asset tracking
Position, temperature and motion data gathered and sent to a central dashboard.
Retail & stock sensors
Shelf fullness, temperature and motion sensors monitoring store operations.
Smart city solutions
Environmental measurement in parks, waterfronts and public spaces, with a live data dashboard.
Custom sensor & device design
Project-specific hardware design, PCB layout and production planning.
Data visualisation
Turning collected data into dashboards and reports for decision-makers.
How we work
Five steps from idea to field
1
Discovery
We listen to the need in the field and document the existing infrastructure and constraints.
2
Design & prototype
Hardware placement, interface flows and the integration plan are settled.
3
Pilot
A controlled group of users tries it out in a real environment.
4
Production & rollout
The approved version is produced in volume, deployed and trained.
5
Support
Updates, compliance tracking and technical support continue after go-live.
Why Ets Teknoloji
You work with the team that designs the hardware, not a reseller
Hardware and software in one hand
We develop both the device and the application, so an interface change, a device setting and the server side can ship on the same day.
Proven in the field
Time and attendance, loyalty and vending projects are systems that people actually use every day — not prototypes.
EMV and closed-loop, one team
You should not have to change your terminal fleet: we develop both banking (EMV) and closed-loop and loyalty applications on top of existing EFT POS devices.
With you after delivery
Patching, compliance updates and technical support continue long after the project is finished.
FAQ
Frequently asked questions
Yes. Electronics design, device firmware and the user interface are ours; production runs through our supplier network. That keeps both cost and supply continuity under our control in volume manufacturing.
Usually not. We install the new system on top of your existing data and run the migration through a controlled transition plan. We review your data structure first and produce a clear roadmap.
We work with widely deployed brands and models. Send us the terminal model you plan to use and we will tell you our support status for it, plus the development time it needs.
Contactless card reading is our core solution. Depending on the machine's payment infrastructure, card, mobile wallet and QR-based alternatives can also be evaluated; we present options based on machine model and expected transaction volume.
We evaluate wired and low-cost short-range wireless options together, depending on the scope. Technology selection happens after we understand the layout of the measurement points and how often data needs to be collected.
We have experience developing applications at EMV L2 level, and we can provide technical support during L3 certification testing. Certification itself is your bank's and the test laboratory's process — we develop the application, verify it on the device and carry the technical load during testing.
No. Closed-loop applications keep the balance and the points on the card itself and never connect to an external payment network, so there is no EMV certification process to go through. The application is also easy to update as the scope changes, which shortens time to market considerably.
Card data is processed on the terminals and never transferred to our servers. At project start we document which personal data is processed, where it is stored and how long it is kept; we prepare the information notice and retention policy together with you.
