Square vs. Groupon- who will win?

Before the much anticipated Facebook IPO later this week, let's take a look at the new phenomenon in the mobile space. Leading the way is mobile payment system, Square. I also got a sneak peak at the competing Groupon, which looks like a bulky iPhone cover with a slit to slide a credit card, now on beta.

What do Square, Groupon as well as Paypal and Intuit have to do with the food industry? Well, this new form of point-of-sale system has created traction from SMBs- food trucks, farmer's market vendors, mom-and-pop cafes, etc. Is it really time to throw away the traditional cash register and credit card machine? One thing is for sure- Visa, Mastercard and Amex are still happy campers.  The Cash Only signs at food trucks, for example, will soon be a thing of the past.
