My sister, her husband, and his brother are in a band. I recently went to one of their concerts. During a break, I mentioned Square, and showed them my reader.

My sister, her husband, and his brother are in a band. I recently went to one of their concerts. During a break, I mentioned Square, and showed them my reader. My sister handed me her phone, I installed the square app, registered an account for them and 5 minutes later they were taking credit card payments. Anecdotally, they sell 10-12 more CDs at a show when they are able to take credit card payments.
