Tips: Many rich people have bound all bank cards in many channels, which can break through the limitation of single card and improve convenience, but sometimes it is necessary to do a good job in card security. You can use some bank cards that are not very easy to use as transit cards for subscription funds. Some extremely important cards still need to be protected by the rich.
