Whole Foods Market (NASDAQ:WFM) is bringing a modern payment system into its stores. The grocery-chain operator announced that it has signed a deal with e-payments specialist Square to bring the latter's systems to some of its prepared food and beverage counters in select stores. These venues will use Square Register and Square Stand to accept payments from customers, allowing them to pay directly at the venues, as opposed to the traditional method of waiting in line at a checkout register.

The terms of the deal were not disclosed.

Whole Foods added that at select venues, customers will have the option to pay with their mobile device using Square Wallet, an app from the payments company.

Whole Foods is slated to release its latest quarterly figures on Wednesday. On average, analysts are expecting EPS of $0.44 on revenue of $4.3 billion.
