Square Cash is a personal payment app from Squareup, the people who make those iPad credit card terminals ubiquitous at coffee shops and farmers markets. Once you've signed up for the Cash app, you can ask them for a debit card, so you can pay people who don't use the app and they can of course pay merchant processing fees and Square can encourage you to leave money in your account to fund the debit card.
I applied for the card, and as part of the process their web site gives you a rectangle in which you're supposed to write something with your finger, I suppose a signature or something. I don't want people messing with my card in case I lose it, so I wrote this:
We'll see how it works.
