>500,000 Square card readers shipped, 1 million Square transactions in May

So, half a million card readers have been shipped and they've each been used, on average, twice in this month? That seems really low to me. Do a lot of merchants get the reader and not use it at all?

A lot of people asked for a reader simply because it's a neat gadget and it's free, never intending to use it in a business.

Yes, we have one and use it infrequently to process event sales, whereas the vast majority of our sales are online.
