The biggest selling point of China Merchants Bank One Fund Card is charity. That is, if you spend more than 20 yuan with the card, China Merchants Bank will make a donation. The more you spend, the more you donate. Let’s pool everyone’s efforts to donate to the Red Cross. Huiyi Foundation. Other functions are the same as those of all CMB credit cards, including card consumption, cash advance, online payment, overseas card swiping, and card swiping with password, etc. The so-called "applying a card with a card" specifically refers to using a credit card from another bank to apply for a CMB One Fund Card, or using a CMB One Gold Card to apply for a credit card from another bank. If it refers to using a CMB One Fund Card to apply for a credit card from another bank, , this is possible to be approved. I have applied for credit cards from Industrial Bank, Minsheng Bank and China Guangfa Bank by providing a copy of the credit card from China Merchants Bank. So whether you can apply for a card with a card mainly depends on whether the bank you apply for accepts it. In addition, I personally recommend that you hold the card for at least 3 or 6 months before trying to apply for a card, because sometimes it takes the bank to hold the card for 3 months before the bank can synchronize the card use records to the People's Bank of China. Other banks can check the card use records of China Merchants Bank. Only on the basis of "card application" will be recognized.
