Instead of the Access Code, Wavespot allows you to configure access to the Internet by asking the customers to input their email addresses, on the splash page.
Here's an example.
In the above splash page, the customer needs only to enter his email ID, and he shall be able to access the Internet at your Wavespot location.
Setting it up
Navigate to User Settings → Splash Template on the top menu bar and select the option "Optional Login with Email Address".
Accessing the Email IDs
The Email IDs collected by the above procedure can also be collated together and downloaded in a single file.
Navigate to Usage Details → Export Patrons' Email IDs on the top menu bar.
Using the drop down menu at the left, select the locations for which you'd like to download the Email IDs. The page gives you option to download the Email IDs, in a CSV (comma-separated values) file. Just click on the corresponding "Download as CSV" hyperlink.
