Users can have up to 4 documents:

- ID front
- ID back

If all 4 documents are verified, user is verified else user is unverified.

User can resubmit for documents that have been rejected.

### **Database Design**

Design tables to store user documents

table:users
(id,username,hash_password,etc)

table:user_documents
(id,user_id,document_name, document_path, document_type, status,etc)

document_type -> selfie
document_name -> fullname
document_path -> path
status - > need to resubmit from admin
