Hi,
Easy Profile does not manage badges natively but there are different ways to make this.
For example you can add a condition to show/hide a field of type HTML delimiter:
1) Create a field of type HTML delimiter (
http://docs.easy-profile.com/index.php/article/html-delimiter-field-type) hat contain a badge called "badge". Se this field to be available only profile page
2) Create another field of radio type with 2 options "Yes" and "No" called "show_badge"
3) in the field show_badge add a condition like this: if equal to custom value "Yes" then show field "badge"
Another way is to add a badge in the views by using Joomla template override feature:
1) Create another field of radio type with 2 options "Yes" and "No" called "show_badge"
2) copy file from /components/com_jsn/views/profile/tmpl/default.php to /templates/your-theme-folder/html/com_jsn/profile/default.php
3) Add a code like this where you want to show the badge:
if( $this->user->getValue("show_badge") == "Yes" ) echo('<img src="/url_of_badge" />')
NOTE: this code is not tested and not supported, it is only for example purpose.
