Square, Inc. has been announced as the exclusive point-of-sale for LouFest 2016 Sept. 10-11 in Forest Park, providing 200 Square Stands to festival vendors, allowing for faster transactions and shorter lines.

For the first time, festival-goers will be able to pay with their phones and credit cards for food and merchandise.

In a statement, Square co-founder Jim McKelvey said: “We’re excited to bring our new reader home to LouFest, so attendees can leave their cash and even their wallet at home, pay with their phones and get back to the music faster.”

McKelvey, a St. Louis native, founded Square with fellow St. Louis developer Jack Dorsey, who of course also co-founded Twitter.

Square, Inc. has already been used at Coachella and other music festivals.
