Utilising the latest technologies in hardware/software and manufacturing,
PrehKeyTec has the ability to design solutions to meet your own
specifications in a timely and cost effective manner.


Our readers support the full RFID frequency range from 125 kHz through to 2.4 GHz and depending on the requirement we can support both NFC and Bluetooth connectivity. Typical applications include identication, security, loyalty recognition, logistics and smart phone connectivity.


NFC offers a contactless exchange of data at a frequency of 13.56 MHz. Working to ISO 14443, ISO 15693 and ISO 18092 standards a fully enabled NFC solution can be offered. NFC is widely used in communicating with NFC enabled mobile devices typically smart phones, as well as other mobile devices and NFC tags.


Our smart card technology supports current standards such as ISO 7816, EMV 2000, Microsoft WHQL, USB CCID and PC/ SC. WE also support the application interface CT-API, which is typically used in the health insurance card / eGK environments. Typical uses include online banking, electronic ID cards, logical access control systems and digital signature applications.


Our ability to offer biometric finger print reading technology allows us to engineer secure systems. Being able to provide both optical as well as capacitive technologies and having the ability to read dry, damp and rough finger prints. Enhanced FBI recognition (FIPS-201 compliant) can also be provided, offering a greater level of security and compliance. For complete system integration an SDK is offered providing support for varying environments and operating systems. Typical applications include access control and identification.


With the ability to offer capture of 1D and 2D barcodes as well as reading travel documents conforming to ICAO 9303. The additional ability to take a photograph of a document is also available, along with the ability to scan paper documents and documents displayed on a smart phone. With the addition of RFID reader a full ePassport or eID can be read. Typical applications include banking, airport check– in and general identification applications.


Encryption of sensitive data is possible with our internal encryption hardware and software. Whether magnetic card data or data from travel documents, encryption takes place within the reading device. This increases security and provides the user with protection from key loggers or similar spy software. Different algorithms (eg AES, TDES) and methods (PKI, HASH, ECDH) are supported, offering a fexible and diverse approach.

[Translate to english:] Custom Input Solutions for HMI


Within the OEM solutions division, PrehKeyTec are able to offer customers a full design and manufacturing service for any data input solution they may need.

With extensive experience designing solutions for demanding applications, extreme climatic conditions, high vibration and for use within rugged harsh industrial environments, PrehKeyTec has the capability to offer an individual, customer-specific design and production service for demanding “Input and HMI” solutions.

Utilising the latest embedded microcontrollers and software, PrehKeyTec has the ability to design solutions against your specifications in a timely and cost effective manner. With experience across Windows, Linux and Android operating systems, as well as with custom drivers and software, as well as extensive experience with a range of programming languages, to include C, C ++, C#, Java, XML, HTML, Scripts, APPs & SDK’s.

With evolving as well as legacy communications systems in use, PrehKeyTec is able to demonstrate competence in a varying number of different interfaces , including serial RS232/485, USB, LAN, WLAN, RFID, NFC & Bluetooth, so whatever communications protocol you require, we have the necessary capability to provide the most suitable for your application and requirements.

Security of data is also an aspect of design which PrehKeyTec can cater for, having capabilities in data encryption using the latest industry standards and government requirements. With a structured approach to all design elements and utilising modern materials (plastic, silicon, metal, glass) as well as alternative assembly and production methods i.e. specialist & industrial adhesive assembly, 3D printing, die casting moulding, specialist silicon’s) , PrehKeyTec is able to recommend the best way forward. With our own in-house production and assembly, we provide multi stage quality control, resulting in highly reliable and durable solutions.

Our services in detail are:
