When combined, 收款码 (shōukuǎnmǎ) literally translates to “receive money code,” a perfectly descriptive name for its function.
The 收款码 is more than just a piece of technology; it's a symbol of China's “cashless revolution.” In the West, the transition from cash went through a long and established credit card era. China, however, largely leapfrogged this stage, moving directly from a cash-heavy society to a mobile-first payment ecosystem.
You will encounter the 收款码 in virtually every transactional situation in China.
The term itself is used neutrally and informally in daily conversation.
