As for the types of bank cards, they can generally be divided into two categories, debit cards (savings cards) and credit cards (credit cards), both of which can be used for capital transactions (or LZ didn't make it clear? As long as the relevant services are handled, it is easy to apply for a savings card, and there is no restriction, as long as the ID card is ready. But it seems that I haven't heard that the savings card will provide door-to-door service, so if you don't want to go to the bank, you can apply for a credit card (many bank employees try to accommodate customers to provide convenient door-to-door service in order to increase business volume and complete tasks).
Credit card application conditions:
At least 18 years old.
Have full capacity for civil conduct.
Stable income and certain ability to pay.
Good reputation.
Most banks have this condition. However, the rigor of operation varies from bank to bank. Another thing to note is that all credit cards must pay an annual fee, which varies according to the types of cards. General credit cards are divided into gold cards, ordinary cards, gold cards and ordinary cards, and there are two kinds of main cards and auxiliary cards respectively. Each bank charges different fees. But personally, I don't think you need a credit card, because the functional savings card you want will suffice. There is really no need to increase expenditure.
I hope my answer is helpful to you.
