Select Pi is used by golfers at driving ranges to register, add value to member accounts and dispense balls in a contactless manner. The app also tracks your account balance across multiple practice facilities. Golfers with a preexisting range card/key will have their balance synced automatically when registering with the same email address on file with the pro shop. Select Pi is a powerful, simple-to-use tool that golfers love. Can be used at any golf driving range with a Select Pi enabled Range Servant dispenser.
