I am developing an iOS app that uses Core NFC to communicate with an ISO 14443 / ISO 7816 smart card. For security reasons, I would like to minimize or temporarily prevent other external communications while an NFC read/write session is active. My questions are: Is there any supported iOS API or entitlement that allows an app to temporarily disable or block Wi-Fi, cellular, or Bluetooth communication while a Core NFC session is active? If device-wide communication cannot be controlled by a third-party app, is there a supported way to guarantee that the app’s own process performs no network communication during that NFC session? Does Apple recommend any architecture or security practice for implementing an offline-only Core NFC read/write operation? The NFC communication itself must remain available during the operation. Thank you.
