SummaryThe supplier is identified as a trading company operating in electronic products and components, with stated import and export scope. It holds ISO 9001 certification and reports written procedures for supplier-service assessment, corrective and preventive actions, and customer complaints. The supplier reports recent new-product development and ODM availability, but no SDK, 3D software design service, or professional technical-supplier R&D capability. Production information lists 100,000 pieces annually for each of five access-control-related product categories, while finished-product inspection procedures are documented and consistently followed. Customization is available across sample-based, design-based, full, minor, and flexible formats. Financial records are referenced for 2022–2024, but no substantive financial results are provided. No customer cases or named customers are disclosed.
CertificationsThe supplier reports ISO 9001 certification for its management system. The slice does not provide the certificate number, validity period, or certification scope, but it is explicit evidence of certification holding.
After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, as well as documented corrective and preventive action procedures. These records directly support an established service-response process.
Production capacityAnnual productivity is listed as 100,000 pieces for each of magnetic locks, electric bolts, electric strikes, fingerprint time-attendance products, and access-control products.
