QR Code

A QR Code (Quick Response Code) is a matrix two-dimensional barcode that can store information such as URLs, text, and contact details, and is widely used in foreign trade. Use cases include: printing QR codes on product packaging to link to electronic manuals or official websites; adding QR codes to exhibition business cards and brochures so customers can scan to get company information or place orders directly; using QR codes on logistics labels to track goods; and completing cross-border payments via QR codes. Precautions: ensure the QR code is clear and scannable, avoiding blurry printing; scanning habits vary by country—European and American customers are more used to scanning to jump directly to web pages, while Southeast Asia may prefer scan-to-pay; QR code content should support multiple languages, and links must be stable and accessible. Difference from Barcode: a barcode can only store numbers or letters, has limited information capacity, and is mainly used for product identification; a QR code has larger storage capacity, can contain URLs, text, etc., and has strong error tolerance. Compared with RFID, QR codes are low-cost but require close-range scanning, while RFID can read multiple items at a distance. In foreign trade, QR codes are commonly used to improve customer interaction and transaction efficiency.
