Why the attendance is showing different addresses even though users check in at the same location?

The GPS accuracy can vary depending on a number of factors, such as the device being used, location accuracy settings, the strength of GPS signal, weather conditions, nearby buildings, network connectivity and many more. This can result in slightly different GPS coordinates for users who are located in close proximity to each other and slight differences in the GPS coordinates may cause variations in addresses translated by different geocoding services.

Different mapping services or applications may use different data source and algorithms to perform the translation or conversion of GPS coordinates to a readable address which result in variations in the addresses returned.

Overall, while the reasons why users might get different addresses even though they check in at the same location can vary, it is important to note that these variations are typically minor and should not impact the overall accuracy of the attendance data.
