If you insist on getting an ICBC card, there are two options among the three.
First, only one credit card, one card with even numbers, debit card and credit card are handled, which is convenient to carry and saves space. But I don't know if I can hang a single chip card.
The second is to run a peony RMB credit card, that is, a UnionPay single-brand credit card. At the beginning of 6222, you can choose to hang a special-shaped single-chip card (around, about the size of a one-yuan coin) as an accessory card, sign an automatic deposit agreement, and automatically deposit electronic cash from the credit card when the electronic cash balance of the chip card is insufficient. This special-shaped chip card has not been widely accepted in most areas, but it will be very convenient soon. For example, the bus system in Shenzhen has now fully accepted this special-shaped chip card.
Do not handle a single chip card separately. For the above reasons, the equipment that can accept single-chip cards is still limited at present, so we have to wait until the terminals are widely rolled out.
