 #### Methods
 
 - `canAddPasses(): boolean`: Check if the device can add passes.
-- `addPass(urlOrToken: string): Promise<boolean>`: Add a pass to the wallet. Returns `true` if the pass was added or if its already added. Returns `false` if the user cancelled the operation. `urlOrToken` should be the pkpass URL for iOS, and the pass JWT for Android.
+- `addPass(urlOrToken: string): Promise<boolean>`: Add a pass to the wallet. Returns `true` if the pass was added or if its already added. Returns `false` if the user cancelled the operation. `urlOrToken` should be the pkpass URL for iOS, and the **unsigned** pass JWT for Android. [Read more here](https://developers.google.com/wallet/generic/android#add-a-pass)
+- `addPassWithSignedJwt(signedJwt: string): Promise<boolean>`: Add a pass to the wallet using a signed JWT. Returns `true` if the pass was added or if its already added. Returns `false` if the user cancelled the operation. This is for Android only. [Read more here](https://developers.google.com/wallet/generic/android#add-a-pass)
 - `hasPass(urlOrToken: string): Promise<boolean>`: Check if a pass exists in the wallet. Returns `true` if the pass exists, `false` otherwise. On Android, this always returns `false`.
 - `removePass(urlOrToken: string): Promise<void>`: Remove a pass from the wallet. On Android, this is no-op. On iOS, make sure you have the correct entitlements. See [documentation](https://developer.apple.com/documentation/passkit/pkpasslibrary/1617083-removepass#discussion).
