1. Available line refers to foreign currency overdraft line+foreign currency deposit.
For example, if the secondary card (USD card) needs to pay overseas tuition, the total cost is $20,000, and the credit line of the main card is $654.38+$00,000 (no arrears), then the user needs to close the RMB bookkeeping and deposit $654.38+$00,000 to conduct the transaction. At this time, if it is useless to deposit RMB, you must close RMB bookkeeping and deposit the corresponding foreign currency. By controlling the flow and available quota, we can smoothly brush out large overseas consumption. Of course, there are also some overseas transactions that are forbidden, such as: buying a house and buying insurance; Some transactions are restricted, such as renting a house: equivalent to RMB 50,000/day and RMB 200,000/year; There is also a limit for overseas cash withdrawal: 1 10,000 yuan/day, 1 10,000 yuan/year (all bank cards under the name, including credit cards/debit cards of domestic users' banks).
2. Currency exchange fee refers to the handling fee rate set by the card organization in the process of converting local currency into clearing currency through the card organization.
The handling fee for ordinary currency exchange is about 65438+ 0.5% of the transaction amount. For example, when spending in Canada: currency exchange fee 1.5%: consumption amount = Canadian dollar consumption amount * card organization exchange rate * 1.0 15: when there is no currency exchange fee: consumption amount = Canadian dollar consumption amount * card organization exchange rate and there is no currency exchange fee, which is very important for long-term overseas use.
To sum up, it is suggested that students who want to go abroad or have plans to go abroad must prepare foreign currency deposits.
