American Express is an American financial group company, and its traveler's checks are widely used in major countries in the world. Traveler's checks are divided into convertible currencies such as USD, EUR, JPY and GBP. Therefore, when studying in France, it is best to use euro traveler's checks to avoid exchange rate losses. It is easier for domestic banks, such as Bank of China and China CITIC Bank, to buy traveler's checks. One thing to remind you is to go to a branch or above to buy, and too small a banking institution does not handle this business. Traveler's checks are mainly used by banks after being converted into local currency, or they can be used directly. Before use, you must leave a "reserved signature" on the check (usually above the check). When using, you must sign the cashier's signature column in front of the bank or merchant staff (generally under the check), which must be consistent with the "reserved signature"! The bank or merchant staff can only make payment after checking that the signatures of the two people are consistent and consistent with the passport and the person. The bank will deduct a handling fee of 7.5%. Traveler's checks are for my own use only. In addition to payment, traveler's checks can be transferred to others. The payee can't pay them directly, but only entrust the bank to collect the money (that's what the merchant does after receiving it). Traveler's checks generally do not expire, and those that are not used up can be returned to the bank where they can be purchased. When buying traveler's checks, you should bring your passport and other documents and full foreign exchange. I can handle it (I can handle it directly for less than $20,000, and I need proof of use for more than $20,000, such as written documents such as foreign admission notice and business invitation letter), and fill out the application form according to the requirements of the bank, which can usually be completed on the same day. After purchasing traveler's checks, you should sign them one by one in the reserved signature column in front of the bank staff. If you don't sign, you can go home and sign, but you must sign before use. Remember! If you don't sign in the reserved signature column before using it, and you can't prove that you are the real holder of the check, the bank can refuse to pay!
