What is a financial security card? How can I change it?

When you manage your finances, you will be bound with a bank card, which is the financial security card. This is a security mechanism introduced by Licaitong to ensure the safety of users' funds. If you want to withdraw cash from Licaitong, you can only take it out to your own security card, which means that even if your mobile phone is lost, you don't have to be afraid of being stolen. As for how to change it, you can enter the wealth management service, click "My"-"Personal Information"-"My Security Card"-"Change Security Card" and follow the prompts.
