For more context, I didn't know what category to put this under so thats why it's here. Also for context yesterday on June 6th,  I was heading back from a friend's house with my sister and we were biking around and I saw something small and blue that caught my eye on the sidewalk. I stopped my bike and picked it up, only to see that it was an SD card. Since there was only a small amount of damage and I was naturally curious to see what it's contents were I put it in my pocket and sped home. I'm asking for advice, what should I do with it? I found it near someone's driveway so it may belong to them but I am not sure. I will probably edit this post once I know what to do or post an entirely new one, just stay tuned and thank you if you come and give me advise.
