Square and Whole Foods announced a deal that will see Square handle payment and checkout at “food venues” within select Whole Foods locations. That would include sandwich counters, juice or coffee bars, pizzerias, or any other type of food establishment within the store. Each of the in-store venues will have an iPad and Square stand where you can swipe your card for immediate checkout. Thus Square users can skip the long checkout lines; indeed those with Square Wallets will be able to pay even more conveniently via mobile. The partnership is Square’s first with a national grocer and represents a big step forward in Square’s trajectory: if it can get into the consciousness of the average shopper, it’s got a very good chance of making itself the mobile payments solution of choice for the foreseeable future.
