Dynamic QR Codes are able to collect scan statistics due to their short URLs.
The different scan statistics collected are:
scans over time (customizable)
scans by operating system
location (country & city)
Visually, this is what scan statistics look like in the QR Code Generator app, which can be accessed by clicking 'Details' from a Dynamic QR Code tile. You can adjust by day, week, or month for more granular reporting and download a CSV of the information for additional analysis.
Static QR Codes do not collect scan statistics.
All data is collected in real-time, meaning you get the most recent data when you check statistics.
