A place that is Attended will show with a blue pin. It means that you provided a photo showing that you were at that place at that time. Preferably a photo you took yourself standing in that location.
If the photo is relatively new, and from your phone, it is likely to have embedded GPS coordinates and a timestamp. This will allow us to verify your visit to the location.
Sample pin popup status:
✖ Unattended (Photo with No GPS data)
✓ Attended (Photo With GPS data)
