Innova Card and Wavecom have launched a hardware reference design for wireless EPOS (electronic point of sale) terminals. The flexible and robust solution provides the possibility to integrate multiple communications technologies without changing the payment and security software, and aims to simplify the design and certification process.
The payment and security core of the joint solution has been developed by Innova Card, a provider of secure hardware and software solutions. USIP is a secure 32-bit Flash microcontroller that has been tailored for the payment industry. It embeds an extended peripheral set including LCD interface, secure keypad controller, thermal printer interface, mag-stripe interface and multiple smartcard controllers.
Furthermore and in order to address PCI-PED 2.0 requirements, USIP provides a wide range of security features such as DPA/SPA resistant cryptographic functions (AES, 3DES, RSA, ECC), a patented on-the-fly external memory encryption engine (based on the industry standard NIST FIPS-197 AES), a secure realtime clock and a battery-backup memory with instant erase capability upon tampering. A full software development environment is available, which includes EMV payment libraries and Linux operating system.
The data communication element of the solution has been created by Wavecom, a provider of embedded wireless technology for M2M (machine-to-machine) communication. Unlike currently available designs which require separate physical interfaces to manage different data communication technologies, the new solution provides a virtualised communication interface.
A virtual communication port consists of placing a layer of abstraction between hardware units and the software running on them, abstracting available system resources from a single physical unit and making it act as multiple, independent logical entities. In the Innova/Wavecom reference design, this means that a single Wavecom wireless CPU (Q2686) can simultaneously manage multiple communication technologies. As a result, EPOS terminals can integrate data reception and transfer via any type of bearer, such as PSTN, WiFi, WiMax, Ethernet, GPRS, CDMA, EDGE, WCDMA or HSPA without any modification to the payment and security interface, thus eliminating the need for multiple certifications.
