What are the functions of the RFID tag?

The RFID tag has 2 functions. 1. To arm/disarm the OBD unit. When RFID tag gets close to the tracker, the tracker will be disarmed automatically. When RFID tag is away from tracker, tracker will be armed automatically. 2. To manage different drivers' information. Each RFID tag has an ID. Every time the driver brings the tag close to the tracker and starts the car, the tag's ID will be sent to the platform, so you can know who is driving the vehicle, and how long he has been driving the vehicle.

AI-Powered supplier vetting

SummaryGuangzhou Topten Electronics Factory is a China-based limited company established in 2024, with 16 employees, a 200 m² manufacturing facility, and two production lines. It offers extensive customization, produces GPS trackers, GSM car alarms, and related security products, and reports CE compliance. The supplier states that finished products receive 100% inspection and that raw materials are traceable, although another record says finished products are checked by packing staff. Export activity is substantial at 90% of total sales, but the stated export experience is only one year. The supplier reports one R&D engineer, no new products launched in the previous year, no Fortune 500 collaborations, and only limited repeat-buyer preference. Evidence regarding after-sales capability and financial credibility is insufficient.

Supplier typeThe supplier is identified as Guangzhou Topten Electronics Factory, a Chinese limited company established in 2024 and operating in Guangdong. Its stated business covers electronics, security products, automotive accessories, and related industrial categories; a separate trade record names TOPTEN ELECTRONICS TECHNOLOGY LIMITED, indicating an associated or related entity, but the exact legal relationship is not fully established.

CertificationsThe supplier explicitly reports CE product compliance and describes production according to the ISO9001:2000 quality management system. However, the slices do not provide certificate numbers, issuing bodies, validity dates, or the specific products covered, so the evidence confirms stated certification/compliance but not its scope or current validity.

R&D capabilityThe supplier reports one R&D engineer and one year of R&D experience, while also stating that no new products were launched in the previous year. This provides explicit evidence of limited documented innovation output and a very small R&D resource.

Production capacityThe supplier operates a 200 m² facility with two production lines and reports 16 total employees, with stated order fulfillment within 15 working days in both peak and off-peak seasons. It also reports 100% finished-product inspection and raw-material traceability, although the separate statement that packing staff check finished products suggests that the inspection process and staffing structure require verification.

Customization capabilityThe supplier explicitly lists customization from samples, customization from designs, flexible and minor customization, and full customization. Its product scope includes GPS trackers, GSM car alarms, vehicle security products, and related tracking devices, supporting relevance to customized electronics and security-product requirements.

Client casesThe supplier states that it has not collaborated with Fortune 500 companies. The available trade record shows one transaction and one associated buyer name, while the repeat-buyer preference is reported at 10%–30%; these details provide limited customer evidence but do not demonstrate a strong portfolio of verified customer cases.
