Unless there’s a way to verify authenticity, which would require central registration of some sort (good luck with that), such a card would be easily faked. It’d impact legit owners more than actual thieves, since many people would probably lose theirs at some point.
Central registration exists already. The two big ones are Project 529 and Bike Index. I highly recommend them. Bike theft is down in Vancouver even while ridership has skyrocketed.
