# SenseCrypt Mobile SDKs The SenseCrypt Mobile SDKs allow a mobile app to read and decrypt SensePrint eID QR codes. The SDKs have two flavours - online, offline. The online SDK is small in size, but it needs to connect with the server for SensePrint eID verification/decryption. The offline SDK is larger in size, but it can be used to verify/decrypt SensePrint eIDs with no network connectivity and completely on a mobile device. The choice between online and offline versions will depend on your use-case and deployment scenario. Both online and offline SDKs are offered for Android and iOS (offline version coming soon). --- # 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.
