"We felt Task was always looking towards the future as we were," said the club's CFO Warren Horton.
"Task's xchangexec solution is not just a POS system, but also offers the capability of the club to move to a fully integrated customer relationship management and loyalty management system, with a sophisticated and scalable POS solution and real-time inventory management."
The MRC's system will run on a dedicated server controlled by Task.
87 xchangexec POS terminals have already been installed at Caulfield Racecourse, and they will be followed by digital signage and menu boards in all restaurants, bars and other food service areas.
The next step will be an xchangexec rollout at Sandown Racecourse, also known as Sportingbet Park.
No indication was given about if or when the system will be extended to Mornington Racecourse.
"TASK was pleased to be invited to the tender process and we were able to demonstrate the superiority of xchangexec and emerge as the front runner," said Task CEO Daniel Houden.
"Our partnership with MRC is thriving and it is a pleasure to work, collaborate and innovate with the MRC team."
