Current passbook is universal deposit and withdrawal in any ICBC in the same city, but a card is required for deposit and withdrawal in different places. Because now the ICBC system cannot handle any business in different places by upgrading the current passbook in different places, it needs a card, which is stipulated in the ICBC documents. Due to the new regulations of ICBC, it is no longer possible to apply for a passbook, nor can it be used with a card. Moreover, the passbook itself cannot be used on ATM machines, so cards are the main ones. Now promote the e-era card. A card can be stored for a fixed period of time, can survive, as well as financial management, funds, withholding. It is more convenient and the future trend is that cards will replace passbooks, so passbooks will be gradually eliminated. At present, many banks are also the main push cards, and they are not worthy of passbooks. Because the passbook has few functions and is not practical, it is actually inconvenient.
