Wallet

Register

If the user's login result loginStatus is pinRequired or registerRequired, proceed with the registration process.

loginStatus	Description
pinRequired	Creates the user's wallet and registers the app.. Requires the user to input a PIN for the initial wallet creation. It is recommended to request the PIN input twice for verification.
registerRequired	Since this process registers the account of an already created wallet with the app, one PIN input is required for existing PIN verification.

Wepin provides a UI Library for receiving the user's PIN input. Use this library to receive the PIN from the user, and then use the result to proceed with the registration process. Refer to the PIN pad library list for each platform on the API overview page.
