03Decision layer · before the hardware matters

Three things the buyer
has to get right first.

SDKTemplatesInterface

An engineering bench under an inspection lamp with a finished circuit board assembly, a magnifier arm and sample connectors

The SDK and the licence

A module is only useful if the SDK is documented, the demo routines run and the licence allows your commercial model.

48-hour FAEFree SDKDevice manual

A single technical drawing sheet seen from above with a pen, folding dividers and one teal sticky tab

Where the template lives

On the device, on a card or in a cloud service. That choice sets your data-protection obligations, and it is yours to make.

Template storagePrivacyArchitecture first

Interface and power

The supply rail, UART or USB, and the wake behaviour drive the rest of the terminal design. Changing them after tooling is expensive.

04Trust layer · standards

What each rule covers,
and what it does not.

FCC Part 15REACHRoHSUN 38.3

FCC Part 15: the class is a marketing limit

A device sold for residential use is Class B. A commercial-only unit is Class A and cannot be marketed into the home.

REACH attaches to the article

Above 0.1% by weight of a substance of very high concern, Article 33 requires that information to travel with the article.

RoHS restricts ten substances

Cadmium at 0.01%, the other nine at 0.1% in homogeneous material, with the technical file retained for ten years.

In a store, the operator writes the spec

A loss-prevention specification usually matters more than a standard. Get it in writing before tooling, not after.

05Execution layer · how we carry it

One contract across
two separate factories.

6 service lines1 contract

SVC-01

Sourcing & matching

The identity side and the retail side are different factories.

We place both under one order, one inspection regime and one export motion.

SVC-04

Technical assessment

A module that arrives without a usable SDK.

We check the interface, the licence terms and the integration path before you commit to tooling.

SVC-05

Production follow-up & QC

A 500-store rollout needs spares, not apologies.

Pre-shipment inspection to ISO 2859-1 general level II: critical defects accepted at zero, major at 2.5, minor at 4.0.

SVC-06

Export execution

The wrong code on a terminal is a customs conversation.

FOB by default, FCA for inland stuffing. Apparatus with an individual function sits in 8543.70.98; telecom-function units in 8517.79.

4 inputsthen a quotation

A technical drawing flat on a pale bench with digital calipers, a drafting triangle and sample parts — Fig. C **The interface you have already designed around** is the constraint we quote against.

01Terminal or moduleDrawing, enclosure constraints, and whether you buy the module or the finished unit.

02Identity architectureWhere the template lives, and which matching mode you need at the door.

03Volume and marketFirst order, annual volume, destination market and the radio approvals it requires.

04Acceptance criteriaThe defect class you want written into the purchase order, and who tests it.

A finished coiled anti-theft retail display cable in close macro, with a matte grey recoiler housing and a machined connector shell at the top — Fig. D **30,000 pulls** is the durability number a store operator will ask for.

A blank unmarked form on a clipboard with a pen, abstract ruled lines and empty tick boxes — Fig. E **One page is enough to start.** The written assessment comes back first.
