ABOUT SPINTAG

SPINTag is a geospatial photography app built for field surveys, site inspections, project monitoring, infrastructure documentation, compliance reporting, and geospatial data collection. Capture high-quality photos with GPS coordinates, timestamp, reverse-geocoded address, and an on-device DigiPIN generated from GPS coordinates.

DigiPIN is India’s official digital addressing system from the Department of Posts / India Post. Any DigiPIN shown in SPINTag is generated locally from the device's GPS coordinates using the publicly available DigiPIN specification published by the Department of Posts.
