# Mobile Pass Mobile passes for Apple and Google Wallet can be linked to either a crypto wallet or an NFT, which allows for a broad range of use cases, such as in-person offers, tickets, and reservations. The provided API endpoints for generating and validating passes enables you to communicate with users through location-based notifications and real-time updates. Additionally, for passes linked to NFTs, we monitor ownership changes through token transfer events and cancel passes if an NFT is transferred. Our top priority is security and safety, and we do not monitor any user data. Although we allow passes to send location or date-based push notifications, this feature interacts directly with the Apple Wallet and Google Wallet APIs, and we do not have access to any user information. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
