I'll tell you my Streetpass story to help you out. On January 2013, I began to Streetpass, with no luck at all. Four months later, I got my first tag at a mall, and it turns out the person is not from my area. Then in August, I realized that the July 2013 update allowed me to get streetpasses in relay points in places like McDonald's, Home Depot, or Best Buy. (1/2)
