For international trade, products must meet CE, FCC, and RoHS certifications to ensure electronic safety and environmental compliance. Key technical specs include fingerprint capacity (standard models support 10-20 prints), battery longevity (look for units providing 3,000+ unlocks per charge), and the presence of an emergency USB charging port to prevent lockouts when batteries fail. For office furniture manufacturers, verify that the lock dimensions are compatible with standard 16mm or 19mm drill holes.
