The differences are as follows:

Two different international credit card organizations provide you with their own clearing networks, just like China Mobile and China Unicom, which provide you with their own mobile phone networks.

As the merchants of these two international organizations are widely distributed all over the world, it makes almost no difference to our general credit card users.

the VISA logo is blue on the back of the card. This is VISA Electron, a sub-brand of VISA's debit card. These cards all start with 42, or if there is no visa logo, they are UnionPay standard cards starting with 62. Both cards are issued by CCB, but for compatibility reasons, Beifen mainly issues VISA Electron cards. There is no difference between the two cards in use.

if it is a credit card, it is the difference between a dual-currency card and a single-currency card.
