Is Square Cash the TKO Winner of the P2P Fight?

NEW YORK (MainStreet) — When comedian Dan Nainan found himself out of cash to tip the coat check person at Nobu 57 in midtown Manhattan, he had a epiphany. "What's your email address?" he asked her.

When he had it, he made a few clicks on his phone and just about that fast $1 rocketed off to her.

"It was that easy," said Nainan, who explained that the tool that powered that exchange is Square Cash.

Up in San Francisco, marketer Joel Goyette said he has used Square Cash to pay lots of bills, from settling up with Craigslist vendors to reimbursing friends for his share of weekend trip expenses. Did he encounter friction when he paid with an email?

"The reaction has been mostly positive, since I'll often just send the money without much explanation," he said. "When there's $375 waiting in your inbox, most people don't protest."

Getting the idea it's time to take a look at Square Cash?

From the Wall Street Journal to the New York Times, numerous outlets have rushed to declare Square Cash, a comparatively new offering from the company that invented a way for just about anybody to accept credit cards, the new winner in the person-to-person payment wars.

That's important because, frankly, maybe until right now, more words have been written about p2p - short for person to person payments - than there have been dollars exchanged.

That's not been for lack of cool competitors, from Google Wallet (which transforms Gmail into a money transfer tool) through PayPal and the startup favorite Dwolla.

But nobody much used any of them and loud as the buzz has been around p2p, the consumer indifference has been louder.

Until Square Cash, which has unlocked the secret of making it so easy to execute p2p, anybody with an email address and a United States issued debit card can send a payment to anybody else with a similar card.
