Yes, for a car, it's a Velcro system, so there are 2 small patches for the front plate and 2 others for the rear plate. You stick one patch on the plate and the other on the car. It holds very well.
I ordered this product and it is for an exchangeable plate. So Velcro with loops for the number plate (front + rear) and two sets of Velcro with barbs for each vehicle (2x front + rear). That's how you get the 6 pieces in the picture.
This is quite possible. However, it depends on the duration of use and the installation. There may also be a slight difference in colour. Depending on the colour, this should be able to be corrected with polishing.
