We cover the full stack — from driver-level firmware to high-level application design, and from greenfield implementations to security audits of existing systems.
What we do
Low-level driver and protocol work
When off-the-shelf readers don't match your hardware or use case, we can implement custom drivers and daemons. We have shipped a TTY/serial-based UHF RFID daemon (C++20, JSON protocol, drop-in compatible with existing NFC tooling) to bridge UHF readers into a unified tag-reading stack.
If you are picking chips or modules for a new product, we can advise on what to use and what to avoid — antenna design, protocol support, power budgets, and firmware pitfalls included.
Custom analysis tooling
We maintain a custom tooling for reading, writing, and analysing NFC/RFID tag content. It handles:
- Tag import/export across common formats (Proxmark3, Flipper Zero, Chameleon Ultra)
- NDEF packing/unpacking and block-level inspection
- Pattern identification, XOR analysis, and visual annotation
- Hardware reader integration via daemon processes or direct serial protocols
If you need to understand what is actually on your tags — or debug why two readers disagree — this is the tooling we reach for.
High-level system design
We design and review application-layer architectures around RFID/NFC: tag data models, authentication flows, offline/online validation strategies, and integration with back-end systems. If you are building access control, product authentication, or supply-chain tracking, we can help you get the design right before you commit to hardware.
Validation and security auditing
We have the lab equipment to test real-world implementations:
- RFID/NFC analysis and emulation (Proxmark-class sniffers, Chameleon-class emulators)
- Wired access-control bus testing (Wiegand sniffers and injectors)
- UHF serial readers for long-range / industrial RFID
- Standard NFC readers (ACR122U, PN532-based modules)
We can verify both the hardware behavior (range, coupling, error handling) and the content security (data structures, authentication logic, replay resistance) of existing or planned systems.
Typical engagements
| Stage | What we deliver |
|---|---|
| Architecture review | Recommendations on reader modules, antenna layout, tag types, and protocol choices for new designs |
| Implementation | Custom daemons, drivers, or host-side tooling to integrate RFID into your product or pipeline |
| Security audit | Hardware and content-level testing of deployed or prototype systems, with concrete findings and remediation advice |
| Knowledge transfer | Documentation and training so your team can maintain or extend what we built |
