RFID Tag

RFID tag (Radio Frequency Identification Tag) is an electronic tag that uses radio frequency signals for contactless automatic identification, typically composed of a chip and an antenna, capable of storing unique identification information. In foreign trade, RFID tags are widely used for cargo tracking, inventory management, supply chain visibility, and anti-counterfeiting traceability, especially suitable for high-value goods, electronics, apparel, and pharmaceuticals. Usage scenarios include: exporters affixing RFID tags to containers or individual items so that customs, ports, and warehouses can read them quickly; cross-border e-commerce using RFID for automated sorting and inventory counting. Precautions: frequency bands differ by country (e.g., 902-928MHz in the US, 865-868MHz in Europe), so compliance in the target market must be confirmed before export; tag costs are relatively high, so return on investment must be evaluated; metal and liquid environments can affect read rates, so anti-interference tags should be selected. Compared with barcodes, RFID enables batch reading, requires no line of sight, and allows data to be read and written, but costs more; compared with NFC tags, RFID has a longer read range and is suitable for logistics links. Foreign trade practitioners should pay attention to international standards (such as ISO 18000-6C) and customers' requirements for tag data formats.
