What needs to be reminded is that you should keep the signing form for going abroad so that you can compare the statements carefully. In addition, there are some tips for using international cards abroad. For example, in foreign countries, payment is authorized by signature instead of password or certificate, so the first thing to do after handling an international card is to sign your name in the signature column above the magnetic stripe behind the card, which is not easy to be imitated. Write down the service phone number of the credit card. If you find the card lost, you should report it as soon as possible to avoid being stolen.
When shopping abroad, you can usually get a tax refund. If a credit card is used, the tax refund will be directly credited to the credit card account, which is simpler than the tax refund procedure after cash consumption. Pay attention to the currency of consumption when using cards abroad, and the price difference between different currencies is very large. When filling in the purchase order, pay attention to the amount under each column. Generally, there are three columns: basic consumption amount, tip and total amount. When signing, you must carefully check the total amount and calculate it correctly. In addition, when traveling abroad, try to separate credit cards from identity documents (including passports, identity cards or Hong Kong and Macao passes) to avoid the trouble of reporting the loss after loss.
