AI-Powered supplier vetting

SummaryQuanzhou Jianghe Technology Co., Ltd. is identified as a Chinese manufacturer/factory specializing in RFID cards, stickers, labels, and readers. The supplier reports more than 15 years of RFID hardware production, design, and R&D experience, over 6,000 customers, more than 300 employees, multiple production lines, ISO9001 factory certification, and CE/RoHS product compliance. It also reports RFID sticker/label output of 200 million pieces and broad export-market coverage. However, the records contain major inconsistencies: one profile lists only 8 employees, while another states over 300; quality assurance and traceability status are unknown, with zero quality-control test equipment recorded; no written complaint-handling or corrective-action procedures are available; and no SDK, overseas warehouse, or overseas showroom capability is reported. Financial evidence is represented only by years, not assessable financial metrics.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company in Fujian, China. Its stated business and product scope includes RFID cards, stickers, and readers, supported by a company description focused on RFID hardware production and IoT solutions.

CertificationsThe company states that its factory has passed ISO9001 and its products have passed CE and RoHS. An SGS audit record is also provided for the supplier, but the audit result is recorded as 0 and the meaning of that value is not explained, so certification evidence is positive while audit standing is not fully clear.

After-Sales capabilityThe supplier has no written procedures or records for corrective and preventive actions or customer complaint handling. It reports in-stock service capability, but has no overseas warehouse or showroom, and the absence of documented service controls indicates insufficient evidence of a robust after-sales system.

R&D capabilityThe supplier reports more than 15 years of RFID hardware production, design, and R&D experience, which supports established technical development capability. However, it explicitly has no available SDK, limiting evidence of software-development or integration support.

Production capacityThe supplier describes five smart-card lines, ten RFID sticker lines, four RFID industrial-tag lines, and four RFID equipment lines, with reported RFID sticker/label output of 200 million pieces and one-month off-peak lead time. The employee count is inconsistent across records—over 300 in the company description versus 8 elsewhere—so capacity claims should be verified, although the production-line and output evidence supports substantial manufacturing capability.

Customization capabilityThe supplier explicitly provides OEM services for well-known brands and reports production, design, and R&D capabilities in RFID hardware, supporting product customization. No SDK is available, and outsourcing procedures and manufacturing contracts are listed as unknown, so the evidence is stronger for hardware OEM than for software or outsourced customization.

Client casesThe company states that it serves more than 6,000 customers, providing direct evidence of a broad customer base. The records do not identify customer names, industries, order details, or independently verifiable case studies, so the breadth of claimed experience is clear but specific customer-case quality cannot be assessed.
