I recommend a new platform for everyone, which is much more useful than Smart Mi Yuan. It's called Card World. It is a very reliable credit card repayment and swiping software. At present, Peng has used this platform for more than a year and it has always been very easy to use. Card World's repayment principle is easy to understand, that is, the remaining amount in our credit card is swiped out and returned many times to pay off the current bill, and the newly swiped amount is included in the next bill, which is equivalent to safely delaying the bill with a little handling fee.
if you don't understand anything, you can refer to the detailed video teaching provided in the "Instructions for Use".
