Modern industrial interfaces are much more than traditional keypads with buttons. At Qwerty, we transform them into intelligent communication systems by integrating advanced electronic components directly into the structure of the membrane keyboard. This approach enables the creation of compact solutions that combine control, identification, and signaling functions in one device.

Our advanced technologies for integrating electronics with flexible surfaces allow us to offer interfaces with built-in QR codes, NFC modules, and LED systems. These seemingly small additions radically change the way industrial control systems operate.

QR code technology within the foil structure

Printing QR codes directly onto the foil surface of the keyboard is a technology we continuously develop and improve. Unlike adhesive labels, our codes are an integral part of the graphic layer, produced using the same printing techniques as the button graphics.

Industrial durability

The use of specialized ceramic inks ensures consistent readability of the code throughout the entire service life of the keyboard. Intensive cleaning with industrial agents, UV exposure, or mechanical abrasion do not affect its functionality. Our laboratory tests confirm code readability even after thousands of industrial cleaning cycles.

Practical applications

Each QR code can store up to 4,000 characters of information, allowing complete device documentation to be embedded. A production line operator scans the code and instantly gains access to user instructions, technical parameters, or service history. A technician has immediate access to wiring diagrams and spare parts lists.

This is particularly valued by maintenance departments in large facilities. Instant access to technical documentation significantly reduces service response time—no more searching through binders or databases; everything is available on a smartphone.

NFC modules in everyday use

NFC (Near Field Communication) modules integrated with the keyboard open new possibilities for access control and process automation. Unlike QR codes, NFC enables two-way communication and can be programmed in real time.

Integration with management systems

Keyboards with NFC modules automatically recognize authorized users when a company card or smartphone is brought near. The system can then adjust the interface to the operator’s privilege level—from basic functions for production staff to advanced diagnostics for engineers.

Security and access control

NFC technology also enables encrypted storage of configuration data directly in the keyboard. Machine settings can be transferred between workstations simply by tapping an NFC card. This solution is ideal for serial production, where different product variants require specific technological parameters.

LEDs embedded in the flexible surface

Traditional indicator lamps take up space and require dedicated mounting holes. An alternative is integrating LEDs directly into the membrane structure, significantly saving space and simplifying construction.

Technology of printed conductive traces

This process uses special conductive inks to create precise electrical paths on the foil surface. LEDs are mounted using SMT (surface-mount technology) and secured with a transparent protective coating. The entire structure retains the flexibility typical of membrane keyboards.

Multicolour status signaling

Each LED can emit various colours, indicating machine status or process progress. Red means an alarm, green indicates correct operation, blue signals standby mode. Adjustable light intensity allows brightness to be adapted to changing lighting conditions in the production hall.

Modern LEDs offer a lifespan exceeding 50,000 hours while maintaining their original brightness. Appropriate construction protects them against moisture, dust, and vibrations typical of industrial environments.

The power of all technologies in one interface

The real strength of innovative solutions emerges when all technologies are combined in a single interface. A keyboard with built-in QR code, NFC module, and LEDs becomes an autonomous communication center between human and machine.

Imagine an operator bringing an NFC card close to the keyboard—the system automatically loads their profile and adjusts the interface functions. LEDs signal machine readiness. At the end of the shift, the operator scans the QR code to submit a production report. All data is sent directly to the plant management system.

In such a scenario, integration eliminates the need for separate NFC readers, signal lamps, or code-scanning terminals. One interface replaces several devices, simplifying wiring and reducing the risk of failure.

Qwerty on the path to the smart interfaces of the future

Integrating electronic components with membrane keyboards is only the beginning. The future may bring solutions combining interfaces with augmented-reality systems and AI-based analytics platforms.

We anticipate the development of adaptive interfaces that automatically adjust to the operator’s preferences and experience. The combination of biometric sensors with machine learning algorithms will make it possible to create personalized working environments in which the keyboard suggests optimal settings or reminds users of safety procedures. Such solutions may significantly reduce operator errors and increase production efficiency, especially in processes requiring high precision.

Even today, we know that by combining the traditional durability of our keyboards with modern communication technologies, we can create interfaces that not only control machines but actively support operators in decision-making. This is a natural evolution of industrial control systems toward fully digital factories and smart interfaces of the future.
