Tools for the Control Enthusiast • Rental Tracker℠ provides you with timely and important information about your rental when you need it. • Manage your Emerald Club profile, view your progress to the next Emerald Club tier and credits toward free rental days. • Extend your rental directly from the app by simply choosing a new return date. Virtually everything you need to get on the road • With Emerald Checkout℠, you can take control to a whole new level at Emerald Aisle locations. Scan a vehicle in the aisle (and view details like mileage and features), confirm your rental options and accelerate your exit process with a Virtual Pass barcode. • Choose your vehicle from virtually anywhere with Virtual Aisle℠ (available at select locations). Upon arrival, use the app to choose a specific vehicle (with details like mileage and features) and we’ll hold it for 15 minutes so you can show your Virtual Pass, get the keys and go.
