TAG™ is designed to allow first responders and others to turn their phone into an identity. At an incident scene TAG™ may create a Quick Response Code (QR Code) which can be read into existing Salamander emergency management software ensuring interoperability at any incident employing Salamander Intelligent Accountability™ products nationwide. TAG™ users with a SalamanderLive account may electronically join an in progress incident or event submitting their responder record to the acting incident commander to begin accountability tracking. While joined to an incident, the device will post accurate position updates which may be displayed in SalamanderLive™ on a map assisting with command operations such as: task assignment, communication, search, directions, and overall operating picture. Please note continued use of GPS running in the background can dramatically decrease battery life. Users with a SalamanderLive™ account will have the capability to download the following first responder information: rank/title, organization affiliation, National Incident Management System (NIMS) qualifications, and baseline medical information. Additionally, search and download other responder and equipment information as needed from SalamanderLive™ to form crews or teams. A SalamanderLive™ account is purchased separately and validates the responder information by providing a secure token to be downloaded into the smartphone. This ensures that the responder’s organization, rank, and qualifications are secure, current and up to date. TAG™ users without a SalamanderLive account may still create an identity from the following information: first name, last name, phone number and e-mail. The user can then collect the identities of other users to form a crew. The individual identity or the crew/team information can then be collected by other Salamander software applications for use at an incident.
