After the ID card of the Postal Savings Bank expires, there are several ways to update it:

1. Cardholders bring their bank cards and new ID cards to the counter of postal bank outlets to update their retained ID cards.

2. Update your ID card through mobile banking: log in to the Postal Savings Bank APP, select mine, click Personal Information-Settings, click on customer identity information to query and modify, and then upload the existing ID card information for approval. After approval, the update is completed.
