You can apply for a credit card on your mobile phone, fill in the information, upload photos of the front and back of your ID card, then fill in the address and deliver it directly to your home. If you want to apply for a bank card, you must bring your ID card to the bank lobby. If you can't do it on your mobile phone, it's much more convenient to get a card now. There is no such thing as 100 deposit. There is a machine in the lobby that can handle it automatically. It's easy. I hope I can help you.
