1. You need to show your tax refund form, boarding pass and passport. Don't check it first, because the customs tax refund personnel may have to check your things, so you must apply for tax refund first, and follow the instructions of the security inspector, otherwise they will take all the forms away and send them to you, or they will tell you which mailbox to put them in.

2. High-value items, such as watches and high-grade leather goods, should be more than 2,000 euros. They shouldn't be checked. After being stamped by the tax refund office, they should be taken to the airport for security inspection. After passing the security check, you should be checked by the staff of the tax refund office in the boarding hall (to prove that you did take them out of the country), and then give them the stamped tax refund form.

3. the credit card used for tax refund must be an international credit card, such as visa. You can't use UnionPay cards (you can only save exchange fees by swiping UnionPay cards).

4. It doesn't matter if the credit card is not in my name, you can return it to anyone, but only if you meet all the conditions in the above point 1-3. Therefore, if you happen to have no international credit card, it is ok to charge the tax refund to the cards of relatives and colleagues.

5. Tax refund should be guaranteed by credit card.

I hope I can help you!
