I see this as a pretty viable alternative to cash. I don't like carrying any cash, and pretty much rely on my credit and debit cards alone. With this, I can simply Square Cash via e-mail the few establishments/recipients that don't accept credit card. And from what it looks like, it seems to be independent of the sender's e-mail service (unlike sending money via Gmail). Neat.
