These days, there are a lot of innovative options when it comes to luggage tags. Aside from "traditional" tags, there are electronic options as well. Some of these come with barcodes that will allow airport workers to scan your tag to reveal your information; this is a great way to better protect your privacy and prevent your personal information from ending up in the wrong hands. Some other luggage tags will pair with an app on your phone and actually use GPS so you can see where your luggage is at all times.
