The Vega Guest Tagging app is an iOS app targeted at the iPhone 5s in combination with the Linear Pro 5 (https://ipcmobile.com/products/ios-peripherals/linea-pro-5/) from Infinite Peripherals.
The app provides the ability to document and tag photos taken by a given camera / camera man at a given location by specifying the start and end photos of a given photo sequence. Each photo sequence can then be associated with zero or more clients by either manually adding a unique identifier for the client (such as a room or cabin number) or by scanning an Mifare C RFID card in the clients possession (such as their room key) before being added to the system.
The photos sessions, along with the tags can then be synchronised back to System Insight servers via the sync service.
