Cars are increasingly becoming computers on wheels, yet they're still identified by stamped metal plates on the back. Reviver is out to change that with its Rplate Digital License Plates. They're available in two models, one that's powered by a battery and can be self-installed, and one that requires a hardwired connection. The former has a monochromatic HD display, Bluetooth and low-power LTE, while the latter adds front lighting for the display and built-in GPS for mileage tracking, vehicle location, and park/valet modes. Both models offer light and dark modes, personalized banner messages, and in-app registration renewal, and are approved for use in Arizona, California, and Michigan, with more states coming soon.
