In our state, we just update our registration online, no need for stickers etc on the car or it printed on the plate. If a cop needs to check the rego, it comes up on their in-car TARDIS system. I can't see why having to increase the complexity of a license plate is better than that.
I always found whole system so weird. Living in country with plates staying same for whole lifetime of vehicle(or at least until it is moved to "veteran vehicle" status, but that brings new limitations). Just get pay the tax online and handle MOT and everything is fine.
