## 根因

自2022年中国人民银行收紧跨境卡规定以来，外国发行的银联卡店内消费每日硬性交易限额为10,000元人民币（约1,400美元），ATM取款每日单独限额5,000元，由中国银联清算系统强制执行

## 解决方案

1. ```
   Carry a backup Visa/Mastercard for purchases over ¥10,000; use the UnionPay card only for small daily expenses like taxis and convenience stores
   ```
2. ```
   Pre-load a Chinese bank account via SWIFT transfer (e.g., from HSBC to ICBC) and use local debit card which has no foreign card limits
   ```
3. ```
   Request a temporary limit increase from China UnionPay by visiting a branch with passport and proof of longer stay (e.g., work visa), but this requires a Chinese bank account
   ```

## 无效尝试

- **** — The limit is enforced by China UnionPay's domestic clearing system, not the issuing bank; the bank cannot override PBOC regulations (100% 失败率)
- **** — The cap is cumulative across all merchants in a rolling 24-hour window; once the total exceeds ¥10,000, all subsequent transactions are declined (95% 失败率)
- **** — Foreign-issued UnionPay cards registered in Chinese wallets are subject to the same ¥10,000 daily cap, plus an additional ¥5,000 wallet transfer limit (90% 失败率)
