## 根因

菲律宾中央银行（BSP）规定，超过100,000比索的支票需要双重背书（收款人和第二位授权签字人）以防止欺诈；单一背书的支票将被退回。

## 解决方案

1. ```
   Ensure the check has two signatures: the payee's endorsement on the back and a second authorized signatory (e.g., a co-director) on the front; example: 'Pay to the order of [Partner Org]' on back, second signature on front.
   ```
2. ```
   Use electronic fund transfer (PESONet or InstaPay) instead of checks for amounts over PHP 100,000; these do not require endorsements.
   ```
3. ```
   Pre-register the check with the issuing bank's branch manager for a single-endorsement exception, but this requires prior approval and is rare.
   ```

## 无效尝试

- **** — BSP aggregates related checks issued within 7 business days; multiple checks for the same purpose are treated as one transaction. (90% 失败率)
- **** — BSP requires two distinct signatures (not stamps) from authorized signatories; stamps are not accepted. (95% 失败率)
- **** — Philippine banks strictly enforce the endorsement rule at the teller; no exceptions for known customers. (100% 失败率)
