The supplier reports three production lines, RFID and ear-tag output, broad export coverage, and order lead times within 15 working days in both peak and off-peak periods. Its descriptions indicate capabilities in RFID, smart cards, plastic and paper cards, supported by specialized printing and production equipment, dust-free workshops, CCTV monitoring, R&D staff, and quality-control personnel. Evidence confirms product and production capabilities, but does not establish formal certifications, after-sales performance, customer cases, or financial credibility. The supplier’s claimed output and manufacturing resources should be verified because the available information describes the entity as a trading company and provides limited operational detail.

R&D capabilityThe supplier reports experience in developing RFID, smart-card, plastic-card, and paper-card products, with three R&D engineers’ total experience stated. This indicates some development capability, but the slices provide no patents, proprietary technology, new-product examples, or measurable innovation outcomes.
