Intercom systems are the keystone of a drive-thru operation, allowing staff to communicate with a remote menu board, and internally with each other. A wireless headset intercom system means orders can be heard by multiple employees, without creating or being affect by ambient noise. The base stations can often be interfaced to drive-thru timer to provide additional timing data in the form of staff response time.

Communication from the paypoint to fuel dispenser sand other remote areas can be crucial to employee security and safe operation in a service station. A standard wired intercom system will typically consist of a base controller at the paypoint, and call stations with a mic/speaker and a call button in or near each dispenser, with additional stations located in a manager's office, beverage cooler, carwash, cash window, storage areas, or outbuildings.
