Secure Firmware

Our development teams guarantee top-notch firmware level security by following secure coding guidelines adhering to the industry’s best practices. We have extensive experience working with various encryption standards (DES, TDES, AES, and RSA, etc.) to secure sensitive data, encryption key management techniques (DUKPT and Master/Session) and various secure key storage mechanisms.


We specialize in implementing key injection processes (Direct Key Injection TR-31 and Remote Key Injection TR-34) and certificate injection and management processes. We also help with optimizing existing algorithms to reduce firmware memory footprints to match physical memory availability.

We specialize in integrating card reader interfaces (Contact, Contactless, and Magstripe) and other secure peripherals (PIN pads, Pin-on-Glass touchscreens). Our team is experienced in strengthening security by configuring secure booting and tamper/security monitoring modules of the given processor/microcontroller.


We also assist in developing special algorithms to overcome hardware security limitations, for example; PIN pad protection using randomized keypad scanning and additional protection against DPA attacks.

Secure Hardware

Payment Kernel Integration

We specialize in integrating mainstream EMV and regional card association’s payment kernels to Linux based and firmware based payment terminals. Visa, MasterCard, AMEX, and Discover are some of the mainstream kernels and China UnionPay, Bancomat-Italy, Interac-Canada, and JCB-Japan are some of the regional kernels we have integrated into payment solutions in recent years.
We can help at different stages in the product development cycle. Starting from hardware evaluation and selection during the design stage, to board bring-up and hardware troubleshooting in the prototyping stage, and developing manufacturing and automated testing suits during the final manufacturing stage.

Product Development

Multi-Platform Development

Our development teams can support different product platforms from bare-metal firmware based on Linux/Android based payment terminals.
We help our clients to obtain PCI PTS, PCI PA-DSS and PCI DSS certifications for their products and systems. In the process, we help our clients to prepare and compile all of the necessary documentation to achieve PCI certification.

Secure Payment Standards
