This is typically needed during the early integration phase before PreProd / Production Environment gets ready. Mobile SDK sandbox allows you to perform D1 API calls using D1 SDK services in order to fine-tune the Application UI/UX in case you are using one of our Secure Card Display or NFC Payment use cases. ### Configuration In order to use Thales Sample Application please contact to your Thales representative in order to provide complete set of [**configuration parameters**](https://github.com/ThalesGroup/dp-d1-sample-android#configuration) and test **card data** to allow your connectivity towards Mobile SDK Sandbox. ### Supported use cases * Login * NFC Payment service * Secure Card Display service * Physical Issuance service --- # Agent Instructions This documentation is published with GitBook.
