# AI告诉澳大利亚用户PayID支付像银行转账一样不可逆，忽略了NPP的Osko诈骗保护逆转机制

- **ID:** `banking/payid-reversal-scam`

- **类别:** assertion_error
- **错误码:** `NPP-ERR-200-REVERSAL`
- **验证级别:** ai_generated
- **修复率:** 75%

## 根因

澳大利亚的新支付平台（NPP）根据电子支付法典为PayID/Osko支付提供了'诈骗逆转'机制，允许受害者在7天内请求逆转，如果支付是向诈骗者进行的，这与PayID不可逆的普遍看法相矛盾。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| NPP API v2.0 | active | — | — |
| Osko Scam Reversal Protocol 2024 | active | — | — |
| ePayments Code v3.2 | active | — | — |

## 解决方案

1. ```
   Submit a scam reversal request to your bank within 7 days using the NPP's Scam Reversal Form. Example: `curl -X POST "https://api.nppa.com.au/v1/scam-reversal" -H "Authorization: Bearer <token>" -d '{"payment_id": "PAY123", "reason": "unauthorized", "amount": 5000, "currency": "AUD"}'`
   ```
2. ```
   Call the bank's fraud hotline immediately and request a 'PayID recall' under the ePayments Code; provide transaction reference and scam evidence
   ```
3. ```
   Use the 'Confirm PayID Name' feature before sending to verify the recipient's identity; this prevents scams by displaying the account holder's name
   ```

## 无效尝试

- **Contact the recipient directly to request a refund** — Scammers ignore refund requests; the bank cannot force a refund without a formal reversal claim (95% 失败率)
- **File a chargeback with the credit card provider** — PayID payments are direct bank transfers, not credit card transactions; chargeback rules do not apply (98% 失败率)
- **Wait for the payment to bounce back automatically** — PayID payments settle in seconds; there is no automatic bounce-back mechanism for completed transactions (99% 失败率)
