Security, access control & retail tech

Roll one SKU into 400 stores and a single weak component becomes 400 service calls. The mechanical specification decides that rate, not the electronics.

R-01

An estate multiplies one defect

One SKU across hundreds of doors turns a single weak component into hundreds of field failures, so the cable is specified in pulls, not in words.

Identity hardware lives on production records

IC burn-in, key injection, and firmware and MAC version records must be wired into the line. None can be added after production.

Counterfeit exposure is quantified

EUIPO and OECD research finds most counterfeits originate in mainland China and Hong Kong, and that infringed SMEs survive less often.

04Trust layer · standards that apply

What each mark covers, and what it does not.

No holder namesNo certificate numbersNo bare CE claim

01 CE is a manufacturer's declaration It is supported by an EU Declaration of Conformity — EMC 2014/30/EU, the Low Voltage Directive and RoHS. The Commission states the mark is not an approval that the product is safe.

02 FCC Part 15 turns on where it is sold Class A is for commercial and industrial sale and excludes residential; Class B is the residential class. A shelf-edge radio sold into homes needs Class B.

03 National marks are not interchangeable The KC and NCC marks published by the site cover Korea and Taiwan. Other markets need their own approvals; a CB certificate is an input to those, never the approval.

04 RoHS restricts ten substances; REACH has no mark Cadmium is limited to 0.01% and nine other substances to 0.1% in homogeneous materials, file kept ten years. REACH carries an information duty above 0.1% w/w, not a certificate.

05 A terminal battery brings a second scheme A terminal with a lithium battery sold inside China meets CCC under GB 31241—2022 from 1 August 2024 — a different scheme from CE and from the CQC voluntary mark.

Digital calipers closed around a machined aluminium housing beside a blank inspection checklist and a sealed sample bag — Fig. 04Evidence over marks. A measurement with a record outlives a logo on a wall.

A finished populated circuit board assembly standing upright on edge with a matte black heatsink across its upper half — Fig. 05RoHS applies to materials. Ten restricted substances, measured in homogeneous materials.

A finished CRPS server power supply module with a perforated intake face and a gold edge connector — Fig. 06Safety is one standard, EMC another. IEC and UL 62368-1 cover safety; interference is a separate file.

A finished cabinet battery storage unit beside a wall-mounted home storage unit with slim light strips — Fig. 07Batteries carry a second rule set. UN 38.3 transport reports, IEC 62619 and EU 2023/1542 duties.

Five finished objects in one level row on a plain pale surface: a rack battery shelf, a machined coupling pair, a wall storage unit and two further finished units — Fig. 08Every mark has a scope. A scope names a site and a product family, not a catalogue.

Three items on a plain background: a microscope eyepiece, a sealed sample bag with a blank label and a plain laboratory courier box — Fig. 09Verify, do not assume. Standard name, issuing body, scope and site address are the four things to compare.

A Group D line-up on a pale ground: a delivery robot, a thin display panel, smart glasses on a riser and an enclosed 3D printer — AA retail estate programme. 29 models across five families from one 10,000 m² Shenzhen factory that has shipped retail fixtures since 2003, so the estate buys one specification instead of five.

Pick-and-place heads and feeder reels aligned along a single SMT line, seen close down the line — BAn identity terminal programme. 150+ catalogued models and 48-hour FAE support, with firmware, key injection and serial records written per unit on the line.

Two finished industrial computers side by side on a pale bench, one a slim fanless Mini-ITX enclosure, the other a rack-mount unit — CA kiosk programme. A control board specified for a closed cabinet on 9–36 V DC, paired with a 300–5,000 nit display module at MOQ 500 pcs.
