I will travel to Italy with my wife. I'm afraid it's not safe and troublesome to bring a lot of cash. Can I use my domestic bank card to spend money there? There are others.

The general savings card is only UnionPay. Some merchants in Italy can use UnionPay cards, but not all, especially small supermarkets and convenience stores.

Most credit cards are dual-currency. It would be much better to bring a credit card. It is more cost-effective to use UnionPay wherever it can be used. It is better to use UnionPay without VISA or MASTER, which is better than nothing. But if the foreign currency of your credit card is USD or JPY, the bank will charge a foreign currency conversion fee, mostly 1.0%, which is not cost-effective. Therefore, it is best to use the euro card to handle the dual-currency card.

Of course, you still need to bring some cash. It is best to bring euro cash directly. The face value of the euro is relatively large, so you don't need to bring a few. Just hide a lot of it tightly.
