Capabilities

From a protocol document to a production run, with one team owning the handoff.

Most remote programs fail at the seams: ID hands off to electronics, electronics hands off to tooling, and nobody owns the test plan. We keep those stages in one sequence with a named owner and a document at every gate.

How we work

Six stages. A decision and a document at each one.

The sequence is fixed; the duration is not. Each stage ends with something you can review — a spec, a prototype, a test report — before the next stage spends money.

01

Brief & feasibility

Control target, protocol, markets and volume. Gaps listed before quoting.

1–2 weeks
02

Design

Industrial design, mechanical structure, PCB and firmware architecture.

3–6 weeks
03

Prototype

Functional samples for key feel, RF range and firmware review.

3–5 weeks
04

Validation

Pre-scan, reliability tests and a signed test report.

2–4 weeks
05

Tooling

Molds, fixtures and production test equipment released.

4–8 weeks
06

Production

Pilot build, then mass production with lot traceability.

Per order

Ranges are typical for a program with a defined protocol and available samples. They are estimates, not commitments — the schedule is fixed in writing after the brief review.:

Evidence

Every claim has a document behind it.

A spec sheet is a promise. A test report is evidence. We try to keep the two visibly separate, because buyers are asked to sign off on both.

For each program we can provide the approved specification, the key-map drawing, the protocol test plan, the reliability test report and the production test record. Certification copies are provided when they exist for the exact model.

Every claim has a document behind it.
What you can request
  • Approved product specification with revision history
  • Key-map and legend drawing
  • Protocol test plan and result summary
  • Reliability test report for the tested sample
  • Certification copies for the exact model and market
  • Production test record for the shipped lot

What we do not do

The limits are part of the offer.

We are a custom OEM/ODM supplier, not a catalogue. Saying no early is cheaper than discovering a mismatch during validation.

Out of scope by default
  • Claims of compatibility with a brand we have not tested
  • Certification logos without a certificate for the exact model
  • IP ratings without a test report
  • Battery-life figures without a measured duty cycle
  • Retail packaging design as a standalone service
  • App development beyond the BLE interface definition

Tell us which stage you are at.

Some clients arrive with a finished ID. Others have a receiver and a launch date. Both are workable starting points.
