I found this company advertised in this months MBR magazine. It looks like the system dog owners use where a hand scanner will pick up all the info on a hidden tag. I says that in Japan, where the product comes form, motorbikes that are tagged and have the datatag sticker on are TEN times less likely to be stolen. The ad in MBR said the hole kit and registration costs £15. I'm definitely going to register my bike.
