In Texas we don't put registration stickers on the license plates anymore. Instead they issue stickers for the inside of the front windshield. They used to be well made but the new ones are obviously printed out on inkjet printers and would be super easy to fake. The red ink in my official one faded to nothing in a few months. I don't think they considered what would happen when such stickers were used on windows without any anti-UV coating in them.
