The document discusses using NFC (Near Field Communication) and the Salesforce Mobile SDK to build a mobile application that uploads contact information from an NFC tag to Salesforce. It provides an overview of NFC, demonstrates a use case of uploading a business card to Salesforce, and does a deep dive into the source code used to implement the application. Key aspects covered include using a PhoneGap plugin to access NFC on Android devices, parsing the NFC tag data, and using the Mobile SDK to upsert the contact record into Salesforce.
