I used visa, a dual-currency card of China Bank, to do daily shopping. I received a short message and the price of the goods I bought was 1 yen. What is that? Is it a handling fee?

1 yen is to test whether your credit card can be used, and it will not actually enter the bill.

1, Bank of China has no UnionPay logo in all currencies, Japanese yen is a lucky cat, and others should be US dollars.

2. If the US dollar dual-currency card uses Japanese yen, there is a handling fee for converting Japanese yen into US dollars, which is different for each bank. You should ask the issuing bank about this.
