# 主帳戶 🔖
當你有同一家銀行的多張信用卡時（例如玉山銀行的 U Bear / Only / Pi），銀行通常會合併成一份帳單給你繳納。你可以在**主帳戶**欄位新增一個主帳戶，再把這些信用卡帳戶都歸類到它底下。
建立好後，你就能在帳戶總覽看到主帳戶包含子帳戶的階層架構，可用額度也會自動合併計算。
點進主帳戶，可以看到所有信用卡的花費統計，也可以直接對帳和繳費。
點擊上方標題列，可以切換到各個子帳戶，查看對應的花費明細。
### 幾個操作建議
1. 一般帳戶的主帳戶跟信用帳戶的主帳戶彼此互斥：一般帳戶不能放進信用主帳戶下，信用帳戶也不能放進一般主帳戶下。
2. 信用主帳戶底下的子帳戶，建議幣種跟主帳戶一致。像常見的「熊本熊卡」或「幣倍卡」是以外幣為主幣種，就不建議跟台幣卡放在同一個主帳戶下，因為主帳戶計算時可能出現匯差，造成當月餘額跟下個月不一致。
3. 同一家銀行的外幣信用卡雖然不建議放進主帳戶，但你還是可以讓它跟同銀行的信用卡共用信用額度，不用擔心可用額度的計算會有問題。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.moze.app/credit-card/statement-combined.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
