I don't quite understand which bank issued the "global payment credit card" you mentioned. At present, VISA has a wider scope of global payment acceptance, followed by MasterCard, and UnionPay can target China and Asia.

1. If your credit card has the logo of VISA and UnionPay (also known as double-label card), it means that it can be used by VISA merchants at home and around the world, and it should be the most widely used, such as the double-label card of China Merchants Bank VISA Classic Platinum Card.

2. If you only have the UnionPay logo on your card, you may only use merchants accepted by UnionPay in China and Asia. You can get a full-currency card with a single VISA label, which can be used in combination and is popular all over the world.

3. It would be a pity if you only have the VISA logo on your card. You have been abroad, but you can't swipe it at home. UnionPay monopolizes the domestic acceptance market.
