Card Box is a platform for credit card promotion and rebate similar to Card Bank and Shenka New World. Different from these two apps, Card Box also supports more rebate services such as loan application promotion, credit card points, new tasks, fuel economy, credit inquiry, etc. More banks are supported, and all of them are settled automatically.

although the card box has not been online for a long time, it has grown very fast, and it is a dark horse platform for credit card promotion and rebate. The platform revenue model has advantages over Kayinjia and Shenka New World Platform. The only drawback is that some banks' commissions are not as high as the above two platforms, but the difference is not big.
