BALTIMORE — PayRange chief executive Paresh Patel spoke at Vistar’s annual sales conference at the Hilton Baltimore on Aug. 13, building excitement over a freshly inked distribution pact between the payments tech company and supply warehouse.

Vistar, the vend product distribution arm of the Performance Food Group, will distribute PayRange’s mobile payment technology to vending operators nationwide. It’s taking preorders for the Bluetooth wireless devices that are installed inside vending machines and communicate with an app on patrons’ smartphones. They will ship this fall.
