Can you add more info to this?
I searched google for hacks and everything I found was not something targeting a merchant but, rather misusing the square device as a card skimmer, etc.
Your comments lead me to believe that If I were a merchant using square- that somehow a hacker would be able to exploit my square device / software to take advantage of me, or my customers.
